INDOT’s Reference Post System

In 1999, the Indiana Department of Transportation decided that it was time to come up with a system that would help better keep track of features along the roads that for which it was responsible. While is would be based, according to INDOT, on the mileage of the road, it was not a milepost system. It was a locator for maintenance items, other than signs, on the state highway system.

There are many parts to the system. The one that most people would have seen, but not really noticed, were the signs that were put up for use with the system. These consisted of small blue signs with a mile number on it, with a smaller sign, if needed, below it with an offset to that mile on it. The signs themselves were barely wider than the post they were on. Very small in relation to most highway signs. Since they are technically only for INDOT use, their size wasn’t a concern. The public wouldn’t notice them, lessening the sign pollution that departments of transportation have been trying to keep under control forever.

I really wish I could have had a better snippet for the offset post, but then, the idea was to give the reader the image of what they roughly look like, so the reader would know what to look for.

The RPS manual is very detailed in its information. For instance, the picture to the left is listed as “RP_U_40_Post_86,” meaning “Reference Post, US 40, Post 86.” The one on the right is listed as “CUMBERLAND CORP. LINE BR 4588 O BUCK CREEK,” at least in the 2004 manual.

US 40 is a very prime example of why this system isn’t to be used as a mileage post system. The system was setup prior to the 1 July 1999 decommissioning of US 31, SR 37 and US 40 inside the Interstate 465 loop. What was, in 1999, marked as mile 86 on US 40 is, in 2020, at mile 92.37 on that very same road in 2004. In 2016, the last update from INDOT, it was listed as US 40 mile 65.179. The legal definition of US 40 was lengthened when it was rerouted along the southside of Indianapolis on I-465 in 2004. By a little over six miles. By 2016, the extra mileage along I-465 was removed to show a more accurate road mileage count towards INDOT’s limit of 12,000 miles.

But there is a bit more to the reference post system that comes into play. Each highway listed in the RPS not only includes the complete mileage for the road in Indiana, but they are also listed by the mileage per county, as well. For instance, reference post 86 above is listed as Marion County mile 24.06 in 2004. In the 2016 manual, that mileage is 5.027.

Then, the reference post system records almost everything along the road. This includes EVERY village/town/city street that intersects with the posted road. For instance, near reference post 86 is, in the 2004 manual, “86 + 0.21 24.52 IR 4193 LT (DELBRICK LN).” At reference post location 86.21, 24.52 route miles into Marion County, Delbrick Lane connects to Washington Street (US 40) on the left (north) side of the road. Directions are listed from the increasing number of the reference post. Every street is listed, although almost none of them have a reference post sign.

Also, the corporation limits of towns and cities are listed by the reference post location, although there is no reference post installed most of the time. This even includes old corporation limits. For instance, in the 2016 manual, reference post 85+0.686 is listed as “City or Town Limit – Indianapolis.” Post Road is reference post 86+0.668. Legally, Indianapolis continues for another at least two miles (the sign welcoming one to Indianapolis is west of German Church Road, the county line is another mile east of that, but that is in the town of Cumberland. And even legally, Cumberland is part of Indianapolis. It is as confusing as all get out, but suffice it to say, for the past 50 years, the city limits of Indianapolis have been the county limits of Marion County, with some exceptions. Certainly not Post Road.

But the idea of the legal multiplex of I-465 with almost every INDOT road in Marion County (there are two that don’t mix with I-465: US 136 and SR 135) that brings up another question. What about multiplexes of state roads?

When the system was created in 1999, it was designed with a hierarchy of roads. That hierarchy was interstate, US highway, then state road, in that order. INDOT does not use the term “multiplex” officially. It is called “travel over” in Indiana. The following picture comes from the INDOT RPS guide of 1999 showing how “travel overs” are handled when it comes to marking the mileage of the road.

Indiana Department of Transportation Reference Post System Users Guide, May 1999.

As you can see, near Frankfort, US 421 takes precedence with the little blue signs. SR 39 is junior to SR 38 when it comes to the signs, only due to the fact that 38 is before 39 numerically.

The system underwent some changes between 2004 and 2015. In 2015, it was made perfectly clear that the manual may contain some mistakes, but that every effort was taken to avoid them.

There was also a special note involving US 40 in Vigo County. When US 40 was removed from most of Vigo County, and rerouted along I-70 and SR 46, the RPS system was not changed to reflect that. The section of US 40 that “travels over” SR 46 is still labelled as SR 46. Here is INDOT’s explanation: “US 40 in Vigo County has a special issue that needs to be addressed. Due to relinquishments and creating a travel over for US 40, the alignment does not follow the historic path. US 40 now traverses where SR 46 has traditionally been and SR 46 is considered the Travel Over on US 40. However, the existing reference posts are still for the SR 46 route and are running in a contrary direction to the increasing direction of US 40. Therefore, for the purposes of this book, RP and Offset for the first 3 miles of US are based on the State Log Measure until it reaches the traditional location for US 40 and then jumps to RP 11 + 00 at the intersection of SR 46 and US 40.”

I mentioned above about the original system being put in place prior to the decommissioning of routes in Marion County. It is important to note that there were more routes affected than just those that were moved to I-465. Those routes were US 31, SR 37 and US 40. The mileage on those roads got weird, yes. But there were two others that were affected by the change…and one most people didn’t even realize.

SR 135 was rerouted from Troy Avenue to Thompson Road, cutting two miles out of the official route. This just required moving the little blue signs from north of Thompson Road, and surveying what else would need signs. And what wouldn’t.

The other route affect wasn’t even marked when it was decommissioned. Shadeland Avenue on the east side of Marion County was still legally SR 100 from I-465 to US 40 (Washington Street) until 1 July 1999. For the longest time, the only marker on SR 100 was a smaller blue sign below the reference post signs that read “100.”

INDOT has available on their website the RPS manuals for 2004, 2015 and 2016. Also available is the users guide from 1999. Here are the links for each: Users Guide200420152016

1930’s Indianapolis Street Name Changes

Street name changes in Indianapolis have been a constant thing. Major renamings have occurred several times. But minor changes were made throughout the history of the city. Today, I want to look at some of the minor changes that happened, or would have happened, in the 1930’s. There is no particular reason I chose the 1930’s, other than the fact that was the time period that I was researching for something that didn’t pan out.

In June 2019, I wrote an article called “Why Do Indianapolis Street Numbers Start at 9?” Originally, it was planned that 10th would be the first numbered street. But right before Christmas 1931, the City Council decided that the new lowest street number would be Nine. Pratt Street, a historic name in the city, would be changed to Ninth Street. The street had been named after Julius Pratt, a prominent citizen in the early days of the area. “Somebody conceived the idea that the name was not sufficiently dignified and, naturally, it was not difficult to get an array of signatures on a petition to change it.’ (Indianapolis Star, 23 December 1931, pp 8)

A street extension, mostly by the city, but would be taken over by the state later, called for a street name change. Daisy Avenue, a street that connected Raymond Street just east of the White River to Bluff Road was changed to West Street. This was in preparation for the city to complete West Street from 16th Street to Bluff Road. The ordinance making the street name change was passed by the City Council on 15 October 1934. Eventually, the entire section of West Street mentioned (from Bluff Road to 16th Street) would find itself part of the state highway system. South of Washington Street, it became SR 37, replacing Bluff Avenue (Road) and Meridian Street. (SR 37 ended in downtown Indianapolis at the time.)

In April 1937, a “discussion” between the City of Indianapolis and residents of Irvington were started, and finished, about the changing of street names in the neighborhood. The biggest fear was that Julian Avenue, named after one of the founders of the town, would be changed to Maryland Street in an effort to keep street names consistent through the city. The City Council announced that very few changes would be recommended…and there would be public meetings about them as they were announced.

There was a post in one of the newsgroups on Facebook to which I subscribe. The poster was asking about a relative that lived on Manlove Street. What happened to Manlove Street? May 1939, a series of 11 name changes were urged on the northside. These name changes would be between 42nd and 52nd Streets. The names were to be changed to the names of roughly the same streets north of 59th Street.

These name changes were: Arsenal to Indianola; Sheldon to Rosslyn; Hovey to Primrose; Ralston Avenue to Ralston Drive; Schofield to Buckingham Avenue; Sangster to Norwaldo; Manlove to Crittenden; Baltimore to Evanston; Caroline to Burlington; Hillside to Cambridge and Brouse to Allenby. Not all of these proposed changes were actually done.

There weren’t many. Street name changes are not taken lightly due to all of the things that go along with it: new street signs; address changes with the post office; property records; etc. But I plan to cover more as time goes on.

1917: Main Roads to Fort Benjamin Harrison Need Work

When Fort Benjamin Harrison was built in Lawrence Township, in northeastern Marion County, getting there was quite the chore. It has been built along the Big Four’s Bellefontaine, or Bee, line. This allowed steam locomotives to pass by the new Army post on a regular basis. The Big Four, with its affiliation with the New York Central, could get Army traffic to and from the fort to almost any place in the United States without much effort.

The workforce for the new fort would come on either the Bee line, or the new Indiana Union Traction line that connected Indianapolis to Anderson, Muncie and Fort Wayne. Although it didn’t last much more than three decades, this was an important way to access the fort. The station for that interurban line still exists…and is open to the public as a Mexican restaurant (as of this writing) called the Hacienda.

But automobile traffic was becoming more and more important. Even more important was the transit of Army vehicles to and from Fort Benjamin Harrison. To that end, in the spring of 1917, the commander of the station, General Edwin F. Glenn, sought to get improvements to the road system to the fort. With this in mind, he held a conference with Marion County government and business leaders to share what he had in mind.

The Indianapolis Star, 10 June 1917. Map of the north east side of Marion County, showing improvements needed to access Fort Benjamin Harrison.

First and foremost in the General’s mind was the main road to the fort – the Pendleton Pike. Technically, the Pendleton Pike started at the limits of the City of Indianapolis at Bee Line connection to the Indianapolis Belt Railway just east of Brightwood Avenue (Sherman Drive). West of that point, it was called Massachusetts Avenue. The county had taken over the Pendleton Toll Road in the late 1880s. But little was done for its improvement or maintenance. By the time the Army created the fort, the road was little more than a connection to other roads in rural Marion County and downtown Indianapolis. Many battles were fought about the improvement of the road, lasting past the end of World War I, when such improvements were vital.

The Pendleton Pike, in 1917, was being improved…slowly but surely. The plan was to concrete the road from the Indianapolis City Limits to 38th Street, just west of what is now Shadeland Avenue. From there, the first of the two sections to the fort’s main north-south entrance, would be improved with heavy stone. This would take the heavy stone from 38th Street to the old Noblesville-Franklin State Road, or Franklin Road. The next section would be graveled. This section ran from Franklin Road to the Yerger or Acre Free Gravel Road, now known as Post Road. The section of the Post Road, connecting Pendleton Pike to the interior of Fort Benjamin Harrison, was being hard surfaced with a “special preparation,” according to the Indianapolis Star of 10 June 1917.

The next road to get attention was the “54th Street Road,” connecting west from the fort to Millersville. Those of you from the area might be a little confused. The village of Millersville was along the Fall Creek, just inside the Washington Township border at what is now Emerson Way. The main drag from Fort Benjamin Harrison is now called 56th Street, not 54th. That road was built along the half-survey line starting where the Millersville and Fall Creek Free Gravel Roads come together near what is now Emerson Way at Millersville Road. The highlighted section of the following MapIndy photo, from 1952, shows the original route connecting the Millersville Road to the old Fall Creek & Mud Creek Road. (At the time, what is now Rucker Road continued south of what is now Fall Creek Road. It would be that way until sometime before 1962, when two lakes were built. The Rucker Road extension would finally be taken out sometime between 1979 and 1986.)

The Millersville Road, according to the Indianapolis Star “is by no means a direct route to the fort. It begins at Thirty-eighth street and Fall Creek and meanders northeast about eight miles to the famous Baker’s bridge and thence southeast a quarter of a mile to the fort grounds.” Baker’s Bridge is along the old Noblesville-Franklin State Road, now called Boy Scout Road, in the northwest corner of the Fort Benjamin Harrison grounds. General Glenn wanted the entirety of the Millersville Road covered with gravel…a job that, according to the General, with five wagons in two days. The first three miles of the Millersville Road had already been improved with asphalt. The next half mile being oiled gravel. The rest of the road was gravel…and work was being done at the time to repair damage done by large, heavy, loads transiting the road.

Other roads being worked on for access to the fort were the National Road from Irvington to Acre Road, Emerson Avenue, Arlington Avenue, 34th Street and the Acre Road itself.

At the time, National Road was the actual name of the Washington Street extension outside the limits of the City of Indianapolis at Sheridan Avenue in Irvington. West of Sheridan, it was Washington. East of that point, it was the National Road. The first mile of the National Road, from Sheridan Avenue, was being concreted. That would end near what is now Shortridge Road and Washington Street. The next two miles from Shortridge Road east were already concreted at that time. That would take it to a point east of Acre (Post) Road. The Acre Road, as of 10 June 1917, was closed for construction of a stone road stretching five miles north to the Pendleton Pike and into the fort.

Emerson and Arlington Avenues were also under construction at the time. Both were being concreted from Washington Street (both are west of Sheridan Avenue) to the Pendleton Pike. Emerson Avenue met Pendleton Pike at roughly 30th Street. Emerson Avenue, at least the southern section of said, ended at the Bee Line. Neither 30th Street nor Emerson Avenue crossed the railroad tracks, and passage past those tracks was done at an underpass on 32nd Street.

Arlington Avenue meets Pendleton Pike (now Massachusetts Avenue) at 34th Street. Improvements along 34th Street included asphalt paving from the Lake Erie & Western (Nickel Plate) Railroad crossing for three miles to the east to what was the northern section of Emerson Avenue. From there to Arlington Avenue, 34th Street was a stone road. Prior to being called 34th Street, the road was the Fall Creek & Warren Township Free Gravel Road.

It would take some time until the roads were improved for to the General’s liking. With the creation of the Indiana State Highway Commission in 1917, the National Road was taken over as Main Market Road #3. It wouldn’t be until 1923 that the Pendleton Pike would find itself part of the state highway system, entering that system as Original State Road 37. By then, the war was over, and traffic to Fort Benjamin Harrison had, while not stopping completely, had slowed considerably as it normally does after the completion of a war. The fort would, eventually, get its connections to the road system other than SR 67/US 36 (Pendleton Pike). In 1941, 56th Street west out of the fort would become part of SR 534, a designation it would only hold for a few years before that state road was routed straight down Shadeland Avenue. With the building of the Interstate system, which was technically built for the defense of the United States, Fort Benjamin Harrison would find itself with two exits from I-465 (Pendleton Pike and 56th Street) and one on I-70 (Post Road). I suppose the Post Road exit on I-74 could technically be listed as part of that…but it is quite a distance from the Fort.

The Status of Indiana Road Building, 1928

Within the first decade of the second creation of the Indiana State Highway Commission, the state found itself building, maintaining and upgrading roads at a furious pace. Up to that point, the ISHC was taking over roads slowly. This also meant that paving of those roads was slowly creeping forward. But 1928 saw the biggest improvement in state highways to that time. The Indianapolis Star of 16 January 1929 had an entire section called the “Good Roads Review” that covered the feat.

After the passing of the second ISHC act in 1919, the state started adding to the highway system as it could. A limiting factor, at the time, was money. The ISHC finances were slow in coming together. But it was also important to hold to the mandate of connecting the seats of government for each of the 92 Indiana counties to each other via state highways. A program of road and bridge building was pushed by Governor Harry Leslie in 1928. To that end, the ISHC was hoping for a large infusion of money to further the program, and to put Indiana on par with its neighbors when it came to good quality roads. Governor Leslie addressed the General Assembly to pass a bill to give the ISHC an additional 5 to 6 million dollars for the goal.

At the time, the state highway system consisted of 5,000 miles of roads, 2,800 of which were still in need of improvement. Most state highways at the time were gravel. But maintenance costs were skyrocketing due to major increases in traffic. This led the ISHC to believe that paving, instead of maintaining, these roads was both more cost effective and beneficial to the motorist of the Hoosier State.

At the close of the 1928 fiscal year, Indiana had improved 1,060.1 miles of its Federal aid highway system. Most of that was spent towards paving the roads, not just maintaining them. To put it into perspective, Indiana had 4,701.5 miles of Federal aid roads at the end of the same fiscal year. That meant that only 22.5 percent of those road had been improved. This put Indiana 31st in the Union when it came to the mileage of those roads. Most other states were gravelling roads as Indiana was pushing concrete road surfaces. Texas, for example, had completed as much as 50% of their Federal aid roads, much of that in gravel.

The government of the state had placed a higher priority on the “more bang for the buck” idea of infrastructure improvements. This stemmed from when the state would just throw money at projects, and almost had to file for bankruptcy. That in turn led to the Indiana Constitution of 1851, which forced financial responsibility on the government.

But that didn’t help Indiana in the sheer numbers of paved mileage. Illinois and Michigan both had 6,000 miles of paved road. Ohio had 11,000. Kentucky, at the end of 1928, had 4,000.

The plan for 1929 called for 220 miles of paved roads to be added to the state highway system. The Star listed those projects in the collection of articles. US 24 (called State Road 24 in the newspaper – there is no difference, really) would have 75 miles of paving done in 1929: 35 miles between Monticello and Huntington; and 40 miles at the eastern end of the road. US 50 between Vincennes and Aurora would add 50 miles of pavement. SR 29 between Greensburg and Shelbyville, 27 miles, would also get the same treatment. Another planned project was 27 miles of SR 37 between Bloomington and Bedford.

Two gaps in US 27 between Fort Wayne and Richmond would be completed during the summer of 1929. One, a 12 mile stretch north of Winchester. The other, 10 miles south of Berne. SR 16 was planned for 15 miles of paving between Rensselaer and Remington. The last project listed included US 150, with about two miles near West Baden on the list.

The Beginning, and End, of SR 534

As the Indiana State Highway Commission’s inventory of state roads was growing, the thought of putting a bypass around the city of Indianapolis hit the planning sheets. The original plan started appearing on official highway maps in 1932. But little would be done for almost a decade. In 1941, the start of a bypass road was contracted…and built. But there was more to it than just a section along the east side from Fort Harrison to Nora.

Yes, that’s right. From Fort Harrison to Nora. The original road that was started in 1941 followed 56th Street from Fort Harrison out to a new construction road along what was, and still is, the Shadeland corridor. At the time, it was Shadeland Road. But that corridor only ran from 10th Street to 56th Street, creating a dead end road north of 56th Street into the Woolen Gardens. A complete history of the road is available as “SR 100: How did it come to be?

The Indianapolis News, 24 July 1941
Legal notice for contract to build SR 534 from
56th Street to Castleton.

Things started happening on the bypass route in 1941, when the first contracts were let. As is typical of the ISHC at the time, the road was contracted separately from the bridges. The first contracts for the road were let in July 1941. The legal notices were published for the contract, as shown on the left. The bids were to be in the hands of the ISHC by 5 August 1941 at 10 AM Central Standard Time (the time zone Indianapolis was in at the time). The plan was for a reinforced concrete road surface north from 56th Street to the old state road that turned west along what is now 82nd Street.

The bridge over Fall Creek was let out for contract in September 1941, with the description “structure on State Road 534” details as a five span arch bridge “over Fall Creek, 2.7 Mi. North of Lawrence.” Those spans were to be, in order: one at 40 feet; three at 80 feet, and one at 40 feet. The bridge was to be of reinforced concrete arch design. Bids were to be at the ISHC by 10 AM CST on 7 October 1941.

The next leg of the road was published for contract in December 1941, with a due date of 16 December 1941. It was to include 4.578 miles of reinforced concrete from Nora to Castleton. (For the route prior to SR 534 construction, check out 82nd and 86th Street Before SR 534 (SR 100).) This would complete the first opened section of SR 534 in Indiana.

Then World War II started.

The Indianapolis News, of 21 December 1942, opined that the ISHC was in a holding pattern when it came to the building of the bypass road. The road was not mentioned by number, but the route was discussed. “One link, approaching Ft. Benjamin Harrison by way of Allisonville and Castleton, has been completed and is in use. The belt highway, discussed for years, will extend south, intersection Roads 40, 52 and 29, until it reaches the Thompson Road, where it will continue west, intersecting Roads 31, 37 and 67.” With the Shadeland Road corridor only extending as far as 10th Street, this would require the acquisition of right-of-way and building of four miles of new road from 10th Street to Troy Avenue/Southeastern Avenue/SR 29. South from here, the road was already in place as the Five Points Road.

“At Valley Mills it will turn north, crossing roads 40, 36 and 34, eventually intersecting Road 52, where it will join the northern east-and-west link that has been built.” This would put the road along the High School Road corridor on the west side. This would also include a state road that connected US 40 to the Indianapolis Municipal Airport. That state road was designated SR 100 when it was commissioned.

“The practical value of such a construction program has long been recognized, both for ordinary traffic and for commercial vehicles that will be enabled to by-pass Indianapolis without contributing to traffic congestion be traversing the downtown streets.”

The article concluded as follows: “A belt line around Indianapolis has been considered ever since the old days of the “Dandy Trail” when gravel roads were marked and motorists wore linen dusters. The successor to that trail is one of the numerous tasks that are being held in abeyance until the war is won.”

The designation of SR 534 would be applied to the east leg from Washington Street north to 82nd Street, then along the 82nd/86th Street corridor to SR 29, Michigan Road. In the summer of 1949, the following was published in the Indianapolis News: “Some of our highways are known by name as well as number. Thus the route called State Road 534 could be more easily found if you called it Shadeland Drive. This road, leading north from Road 40, east of Indianapolis, intersects with Roads 31, 431, 37, 52 and 29 and is part of what, some day, will be a belt line around the city. But what we started out to say is that on the new Indiana highway maps it is 534 no longer. The new number is 100.”

And with that, the ISHC removed one of the “daughters” of State Road 34, stretching the SR 100 designation from a short section of High School Road to the entire bypass. Or, at least, the sections that would be completed before it was entirely replaced by Interstate 465.

End of Year 1940: ISHC Projects and Contract Bidding

On 13 December 1940, it was announced that the Indiana State Highway Commission was about to open some bidding on projects, and that the bidding would be received by 31 December. These projects included four grade separations, eight bridges and thirty miles of paving and resurfacing.

Sherman Drive and Big Four, 1937
Sherman Drive and Big Four, 1962

One of the biggest projects on the bidding list involved a city street in Indianapolis. Sherman Drive, a major thoroughfare three miles east of the center of Indianapolis, crossed the Big Four Railroad northeast of the railroad’s major yards at Beech Grove. That yard is just over one mile southeast of the Sherman Drive. According to the press release from the ISHC, “among the grade separations to be built are a 13-span structure on Sherman Drive southeast of Indianapolis, to carry traffic over the CCC & St. Louis Railroad yard.” As shown in the picture to the left, this was an at grade crossing of multiple tracks. The picture at the right shows the same area of Sherman Drive in 1962.

Another bridge project opened for bidding at this time was grade separation on the Marion State Road 9 Bypass, crossing over the Chesapeake & Ohio and the Pennsylvania Railroads. That bridge was planned to be a seven span structure. Another bridge to be built in the Marion area was a 392-foot structure over the Mississinewa River on the same SR 9 bypass. The bridge was to have a 28 foot roadway and sidewalks.

Paving projects included in this round of bidding were: 1.291 miles of US 50 realignment in Washington, Daviess County; 4.938 of SR 1 paving from Leo north to Allen-Dekalb County Line in Allen County; and paving 2.391 miles of SR 9 bypass (Baldwin Avenue) from Second Street in Marion, Grant County.

Another SR 9 project in Grant (and Huntington) County included widening and resurfacing 21.30 miles of SR 9 from 1/2 mile north of Marion to Huntington. The road was to be widened to 22-foot wide. Also in Madison County would be the widening of three miles SR 9 from SR 67 north to the Anderson city limits.

The last road project would be the widening and resurfacing of US 31 from the north edge of Franklin to the south edge of Greenwood, through Whiteland and New Whiteland. This contract would include 9.1 miles of highway.

Guard rail projects were also part of the bidding. Those installations would be in Adams, Allen, Dekalb, Elkhart, Floyd, Franklin, Grant, Hamilton, Hancock, Henry, Huntington, Jackson, Jennings, Johnson, LaGrange, Lawrence, Madison, Marion, Miami, Monroe, Morgan, Noble, Randolph, Steuben, Union, Wabash and Whitley Counties. These were on roads 3, 6, 9, 13, 15, 18, 20, 22, 24, 27, 29, 31, 37, 44, 50, 52, 67, 109, 128, 150, 209, 327, 427 and 434.

SR 37, A Review

One of the blogs that I follow everyday is that of Jim Grey. I started reading his blog over a year before I created the Indiana Transportation History Facebook page. It was because of that blog that I asked him to help me admin that group. He was also the one that encouraged me to start this blog…telling me, correctly, that it would be easier to keep track of the information I have been sharing in blog form than in a Facebook group. His blog is called “Down The Road.”

Jim had been sharing his passion for photography and road trips in the Facebook group. His topic has been that of SR 37. Due to those posts, I decided to put together a collection of posts that I have shared over the past 16 months that cover the same subject. Check out his photos on the subject at his blog, or through links on the Facebook group.

Waverly

In the early years of the state of Indiana, a small village located at the Bluffs of the White River became the meeting place for commissioners that set out to determine the location of the new state capital. Two years before that, in 1818, a trail was cut through the wilderness from Brookville that came to be known as the Whetzel Trace. Later on, a road was built north to the new state capital at Indianapolis. Because it went to the Bluffs of the White River, it was called Bluff Road.

Paoli State Road

When the Bluff Road was built, it was included in a longer “state” road that stretched from Indianapolis, through Martinsville, Bloomington and Bedford to Paoli. It would become the basis for original state road 22, and later, the original path of State Road 37.

White River on Indianapolis’ South Side, and its Effects

This article focused more on the effects of the Indianapolis Southern/Illinois Central Railroad, but it DID affect the routing of State Road 37. When SR 37 came into being, it ended at Washington and Meridian Streets, following Meridian Street south to Bluff Avenue (now Road) for its journey out of Marion County. The White River was moved, and the state built a new SR 37 over the old river.

Road Trip 1926: SR 37

On 1 October 1926, the entire state road system was renumbered. State Road 37 was given to what had been State Road 22 from Indianapolis south. The new State Road 37 was designated only south of the capital city.

Winners and Losers, Routing the Dixie Highway Through Indiana

When the committees met to create Carl Fisher’s Dixie Highway, political and personal gain played a part. Especially south of Indianapolis. While Fisher wanted the route to go directly from Indianapolis to Louisville, someone else wanted the same thing…just with a detour through Paoli. The latter won.

Original SR 22 – The “Fight” For the Way to Martinsville

The fastest way to Martinsville from Indianapolis wasn’t always the Bluff Road. When the state started taking over roads, a discussion was had to decide what road would be taken over to get to Martinsville. The choice was between the Vincennes Road and the Bluff Road. Eventually, it would be both.

Removing the Bluff Road Bridge Over the Illinois Central/Indiana Railroad

The Indianapolis Southern Railroad was chartered in 1902, and it crossed the old Bluff Road at an odd angle. The Dixie Highway used the route starting in 1914. In 1923, it became State Road 22. In 1925, a bridge was built over the railroad due to increased traffic on both the road and the railroad.

The Dixie Highway In Morgan County

One of the most bypassed roads in the state is SR 37. And very few more so than SR 37 in Morgan County. But this article focuses on the Dixie Highway through the county…and how it was originally routed through the area.

State Highway Department Construction Plans for 1963-1965

This article is included because part of the plan was to build a new SR 37 through the west side of Indianapolis, and connect it to I-465 at Harding Street. The Harding Street connection would be made. It would be a complete reroute of SR 37 from I-465 south to Martinsville. It ended up that SR 37 would be routed along I-465 from Harding Street to East Street (US 31), and be multiplexed with US 31 all the way to 38th Street on the northside of the city.

Expanding SR 37 from Martinsville to Oolitic

The last article about the routing of SR 37 I want to share is the latest one posted. In the 1970s, SR 37 was being moved and widened from Martinsville to Bedford. The section north of Martinsville had already been moved and widened…in conjunction with the construction of I-465 around Indianapolis.

Expanding SR 37 from Martinsville to Oolitic

20 December 1970. The Sunday Herald-Times (Sunday edition of the Bloomington Herald-Telephone and the Bedford Times-Mail) has as the lead story at the top of page one, “All Four-Lane 37 To Be Started In 1971.” It discusses the last projects that would make SR 37 a divided highway from the Martinsville Bypass to Oolitic. It was the beginning of the projects…all scheduled to start before the end of 1971.

Chairman of the Indiana State Highway Commission at the time, Ruel W. Steele, stated that the ISHC had let eight contracts, totaling over $22.5 million, along the highway corridor. The section between Bloomington and Martinsville was under going right of way purchasing, with construction projected to start in the fall of 1971. Right of way purchasing would consist of one contract. Construction would be divided into two contracts.

“We expect to clear the right of way on the south half of the Bloomington-Martinsville project by some time in July of next year,” said Steele, “and on the north half by September. We expect to have both sections under contract next year – the south half by September, and the north portion before the end of the year.” Construction of this section should go quickly, the newspaper mentions, because it will mostly be widening the current road from two to four lanes in place. “There will be some places along the corridor where the new lanes will be west of the present road, and some where it will be to the east.”

One section was already under construction. A new northbound SR 37 bridge over Indian Creek, south of Martinsville, was being built 60 feet east of the then current two lane bridge. Once the new bridge was completed, traffic would be rerouted to the new facility while the old bridge was rebuilt. In Indiana, most contracts for road construction are let separately for roads and bridges.

Included with the discussions with Mr. Steele was a status report on all of SR 37 from south of Bedford to the south end of the Martinsville bypass. The Bedford bypass was anticipated to start construction in Spring 1972. Due to rough terrain and three sets of bridges having to be built, the Bedford bypass was to be the most expensive part of the entire project. It will be the last project to be put under contract.

4.8 miles of the new highway from Oolitic to south of the Monroe County line was, at this time, 40 percent complete and 15 percent ahead of schedule. Completion was scheduled for December 1971. The next 3.3 mile section, to just north of the Monroe County line, was scheduled for completion by 1 June 1972.

The next 2.5 mile section from 1.5 miles north of the Monroe County line to three miles south of Dillman Road had been let to contract the previous week. This included an interchange at Monroe Dam Road, allowing access to Lake Monroe, and bridges over the Monon and Clear Creek. This section was scheduled for completion by December 1972.

Right of way problems were being resolved for the next 2.5 miles, all south of Dillman Road. Most property had been acquired, but some condemnation suits would have to be filed. The right of way was expected to be cleared within the next two weeks from the publication of this article, except for the condemnation suits which would be filed by 15 January 1971. The new Bloomington bypass would start at the end of this section, one half mile south of Dillman Road.

March 1971 was the scheduled date for the start of right of way purchasing for the south four miles, from south of Dillman Road to SR 45, of the new Bloomington bypass. The Commission expected to have the right of way cleared by August 1971, and contracts to be let by the end of that year.

Four miles of the middle section of the Bloomington bypass, from SR 45 to SR 46, as shown in the newspaper photo above, was progressing quickly. This section was anticipated completed by 1 September 1971. The next section, however, was being re-let when the bids for the first round of contracts came in over engineer’s estimates. The second round of contract letting would commence on 26 January 1971, with “hopefully the contract will be let January 28.”

“Steele said eight separate projects – five highway and three bridge – are now under contract, including the Ind. 46 companion project which extends from the new four-lane Ind. 37 to Indiana University. There are six more projects to be let to contract in the entire relocation from White River to Martinsville.”

In October, 1971, contracts were opened for four projects as part of the new SR 37: the south section of the Bloomington Bypass; additional two lanes on the Martinsville bypass; bridges over Clear Creek and the Monon; and bridges over the Illinois Central Railroad. The Clear Creek/Monon bridge is a twin bridge, each with five spans. The IC bridge consisted of two bridges each with three spans. With these contracts, the only part of the new SR 37 that still needed to be opened to contract bidding included the Bedford bypass and from the north end of the Bloomington bypass to near the Morgan-Monroe County line.

Removing the Bluff Road Bridge Over the Illinois Central/Indiana Railroad

The year is 1902, and the Indianapolis Southern Railroad has just been chartered to enter the city of Indianapolis and rumble through the Marion County countryside south of the city. Once the railroad entered Perry Township from Center Township (at what is now Troy Avenue), the railroad right of way followed the survey line one mile west of the Three Notch Road (Meridian Street) and two miles west of the Range Line (Shelby Street). Just south of what would become Stop 8 Road, now Edgewood Avenue, the railroad crossed the Bluff Free Gravel Road.

Rail and road traffic near this intersection of the Indianapolis Southern and the Bluff Road wasn’t a real problem for several years after the building of the railroad. In 1914, the Bluff Road was to become part of the Dixie Highway. This highway, connecting south Florida to Chicago and northern Michigan, actually connected to Indianapolis, the hometown of its creator, in four different directions. This led to a traffic increase along the Bluff Road, creating more problems at the railroad crossing which was at a very bad angle to begin with.

The problem was made worse when the state took over the Bluff Road in 1923, making it original State Road 22. This made the Indiana State Highway Commission responsible for the maintenance of the very old road. In 1925, the state decided that enough was enough, and a bridge was built over the Indianapolis Southern railroad, which had become part of the Illinois Central.

The bridge that was built was a very narrow facility. Two lanes wide, at best. But it would serve its purpose, creating a safe crossing of the Illinois Central by SR 22, or as it would soon become, SR 37. And it did just that until the state started moving SR 37 to the west in 1964, and completing the job in 1965. The overpass then became property of Marion County. And here is where it went downhill.

Reconstruction work on the deteriorating span was scheduled in both 1971 and 1977. The Indianapolis Transportation Board posted a long list of bridge projects for that year in newspapers in mid May 1971 and early April 1977. By 1984, the city was looking at removing the bridge all together. Unfortunately, getting the right of way to do this proved troublesome. The bridge was built with very little clearance when it came to the actual right-of-way used. It was suggested by John Willen, DOT Chief Engineer, that land acquisition was a problem, and that the bridge would not be replaced due to decreased rail traffic at that location.

Legal notice was published in the newspapers in December 1984 that the Indianapolis Department of Transportation, with the cooperation of the Federal Highway Administration and the Indiana Department of Highways, had decided that the overpass on Bluff Road over what was then the Illinois Central Gulf Railroad would be removed and an at-grade crossing would be put in its place. “The proposed project begins at a point approximately 210 feet south of Banta Road, then extends in a northerly direction mostly along the existing alignment of Bluff Road, and terminates at a point about 750 feet south of Edgewood Avenue for a total project length of 0.42 mile (2,210 feet).” In addition to the removal of the overpass, the following was listed as part of the project: “The portion of Bluff Crest Drive between Bluff Road and Bluff Crest Lane, approximately 280 feet will be removed and Bluff Crest Drive access to Bluff Road will be terminated.”

In September 1986, the city of Indianapolis introduced a resolution to implement a five ton weight limit on the overpass. The notification of the resolution in the newspapers of the time stated “whereas, the Indianapolis Department of Transportation Street Engineering Division was notified that certain portions of this structure had a stage of deterioration.” Prior to this, the bridge had had a ten ton weight limit. In May 1987, the bridge was closed completely as the city of Indianapolis decided it would be better off replacing the structure with an at-grade crossing. The city reported that the work would be completed by 15 July 1987. The original plan to remove Bluff Crest Drive was apparently just dropped along the way. That residential street still connects to Bluff Road in the same location as it had before the removal of the overpass.

On 29 July 1987, the Indianapolis Star announced that “Bluff Road, closed since April from Banta Road to Edgewood Avenue for extensive reconstruction, was reopened for traffic Tuesday (28 July 1987).” The project cost the city $540,000 and involved the removal of the “severely deteriorated Indianapolis Southern Railroad overpass built in 1925.” Even in the end of the overpass’ life, the newspaper still called it the Indianapolis Southern instead of the company that had taken it over just the year before, the Indiana Railroad.

Indianapolis Interstates, Planning and Replanning

EDITOR’S NOTE: This entry is for reporting of history, not to choose sides in the planning of the interstate system in downtown Indianapolis. It is merely my intention to report on what happened.

When the first vestiges of the interstate system was being laid down, the plan to connect downtown Indianapolis to the entire system came up immediately. As I covered in the post “Interstate Plans in Indianapolis,” it was already decided, and approved by local, state and federal officials, that the two “major” interstates (65 and 70) would come downtown, while the two “minor” interstates (69 and 74) would connect to the outer loop interstate (465). All that was left were the details.

And as they say, nothing is set in stone until it is set in concrete. Such is the case with the “Inner Loop,” that section of the downtown interstate which is shared by both I-65 and I-70. The rough route of Interstate 70 has basically been decided through the city. Exact details would come later. But Interstate 65 would be a sticking point in the whole plan. The plan approved by local, state and federal officials would be debated for several years.

It came to a head in summer of 1965, when politicians started becoming involved in the routing of I-65…and the building of the inner loop. And the concern that federal funds would run out before the plan was completed.

Indianapolis News, 20 September 1965. The routing of the interstate system through Marion County had already been approved by local, state and federal officials. But that didn’t stop some people from trying to change them.

Up until the point of the summer of 1965, nine years of planning had already gone into the creation of the interstate system in Marion County. Delay after delay, mainly caused by slight variations in the planning, were in the process of being overcome. The whole plan found itself against a hard “drop dead” date, or what was thought to be a hard cap on said date, of 1972. Part of the legislation financing the entire nation’s interstate system stated that the Federal government would continue to pay 90% of the cost until 1972. “The chance that Congress, about five years from now, will extend the 1972 deadline is a gamble state officials cannot and dare not take.” (Indianapolis News, 20 September 1965)

The latest oppositions (in summer of 1965) came from Congressman Andrew Jacobs and City Councilman Max Brydenthal. Their major hang up with the plans was simply that I-65 should turn north on the west side of the White River, and that the inner loop should be completely depressed from multiplex section (where 65 and 70 share the same pavement) west to White River.

The Interstate 65 reroute from West Street west to 38th Street would, according to the proponents, would accomplish five things: 1) the original plan would dead end 40 streets through the west side, and the new plan would require no closing of streets; 2) the new I-65 route could be combined with the already planned SR 37/Harding Street expressway plans for the west side, lowering the cost of building both roads; 3) more interchanges could be worked in, allowing better access, especially to what would become IUPUI and its assorted facilities; 4) historic landmarks would be preserved (mentioned were Taggart Riverside Park, Belmont Park, and Lake Sullivan); and 5) there would be no delay in construction.

From the other side, the proponents of the original plan responded with six points of their own: 1) the original plans were already in the hands of the State Highway Department’s land acquisition office; 2) Construction design plans were already 85% complete; 3) designs for a bridge north of the Naval Armory were nearly completed; 4) the state already spent, or was in process of spending, $2.4 million for right of way; 5) preliminary planning and design fees had already cost the state hundreds of thousands of dollars; and 6) relocation would set the project back three years.

The other bone of contention was the inner loop…and the prospect of making it a below grade facility. As with the actual constructed facility, the depressed section of the interstate project would be from south of Washington Street to Morris/Prospect Street. The desired change would depress the entire center section, and both I-65 and I-70 from West Street to the combined corridor.

Part of the reasoning, used by those that wanted the highway depressed, was quite simply that an elevated expressway would add to the “blighting” of the area where that elevated was built. “In city after city, past experience demonstrated the blighting effect of elevated roadways (most of which are railroad) and we now have evidence that the depressed roadways actually enhance the value of property in their neighborhoods.”

Another bonus point in the depression of the interstate, say the proponents, is that Indianapolis would have a chance to install new sewers, bigger than the ones that were already in place. This included the possibility of the city/state buying snow melting machinery because the new sewers would be able to handle the increase in volume.

The people that had already done the planning pointed out that each section of the planned inner loop had to considered in sections, and not as a whole. Each section of the entire project had been studied and restudied. There was a study done for depressing the north leg of the project (I-65 from West Street to I-70). It had been discarded. The south leg would be partially depressed (at the east end) as would the east leg (at the south end).

One change in the routing of I-65 had already been put in place. On the south side of Indianapolis, the interstate was originally planned to go through Garfield Park. Now, it goes east of that facility.

In the end, the drop dead date of October 1972 came and went without the completion of the expressways downtown. It would be 1976 until they were opened to traffic. The new SR 37 expressway was never built…and now SR 37 doesn’t even connect to downtown Indianapolis. The original routing and elevation, planned in the early 1960’s, was followed as approved.

Indianapolis and the Original ISHC State Road System

I have posted much about the creation of the Indiana State Highway Commission. As of the posting of this article, the age of the Commission is either 103 or 101 years old. The original ISHC was established in 1917…but met with a lot of problems. It was finally nailed down in 1919 and made permanent.

This also creates a dating problem when it comes to the state highways. The first five state highways, then known as Main Market Roads, were established in 1917 with the original ISHC. Two of those original Main Market Highways connected to Indianapolis. The original National Road had been given the number Main Market Road 3. The Range Line Road, connecting Indianapolis to Peru, and through further connections, to South Bend, was given the Main Market Road 1 label.

When it was finally established, the ISHC changed the name of the Main Market Road to State Road, in keeping with other states surrounding Indiana. The markers used along the roads, painted onto utility poles like the old Auto Trail markers were, resembled the image to the left…the state shape with the words “STATE ROAD” and the route number. In this case, as of 1920, State Road 2 was the original route of the Lincoln Highway through northern Indiana.

The state highway system was designed to, eventually, connect every county seat and town of over 5,000 population, to each other. Indianapolis, as the state capital and the largest city in the state, would have connections aiming in every direction. Most of those roads marked with the original numbers would still be state roads into the 1970s and early 1980s, before the Indiana Department of Highways started removing state roads inside the Interstate 465 loop…and INDOT finishing the job on 1 July 1999. These road were removed for state statutory limitation reasons, and I have discussed that in a previous blog entry. So I won’t do it here.

The original state road numbers that came to Indiana varied greatly, as did their directions. There were no set rules when it came to state road numbers. They were assigned as they came…and stayed that way until the first renumbering of 1923, or the Great Renumbering of 1926.

Let’s look at the original state roads in Marion County, some of which actually did not reach Indianapolis itself.

State Road 1: As mentioned before, State Road 1 was originally called Main Market Highway 1. North of Indianapolis, it followed the Range Line Road, a local Auto Trail, through Carmel, Westfield, to Kokomo and points north. The route north followed Meridian Street north to Westfield Boulevard, then Westfield Boulevard on out to Carmel and beyond. In Carmel, the old road is still called Range Line Road, and serves as the main north-south drag through the town, as it does in Westfield.

South of Indianapolis, State Road 1, like its Main Market Highway predecessor, followed the old Madison State Road out of the city to Southport, Greenwood, Franklin and Columbus. The original SR 1 route is still able to be driven through the south side of Indianapolis, with the exception of the section replaced in the 1950s by the Madison Avenue Expressway. But Old Madison Avenue exists, if you can find your way back there.

While the entirety of original State Road 1 became US 31 with the Great Renumbering, bypasses in Marion County were put in place very early. The northern section, through Broad Ripple, and Carmel was replaced as early as 1930. The southern section, including the Southport/Greenwood bypass, was put in place in the 1940s.

State Road 3: As mentioned above, Main Market Highway/State Road 3 followed the National Road through Marion County. One exception to this is the section of the 1830s National Road that crossed the White River downtown. That section of the old road was removed in 1904 with the demolition of the National Road covered bridge and its replacement with a new, and short lived, Washington Street bridge. With a couple of exceptions other than that (the Bridgeport straightening of the early 1930s, and the new Eagle Creek bridge built in the late 1930s), the old road was followed very accurately until the mid-1980s with the creation of White River State Park. The successor to original SR 3, US 40, was moved to make room for the park. Both US 40 and US 31 lost their designations on 1 July 1999 with the removal of those two routes inside the I-465 loop.

State Road 6: This old state road was a through route when it came to Marion County. From the north, it followed the route of the original Indianapolis-Lafayette State Road from Lebanon. After passing through downtown Indianapolis, it left the county using the original Michigan Road on its way to Shelbyville and Greensburg. The original State Road 6 followed the Michigan Road Auto Trail, not the Historic Michigan Road, meaning it still went to Madison, but it went by way of Versailles, which the historic road did not. With the Great Renumbering, the northern SR 6 became US 52, while the southern SR 6 became SR 29 – later to be renumbered again to US 421.

State Road 22: This road, as it was originally laid out, only lasted from 1920 to 1923. Out of Indianapolis, it followed the old Mooresville State Road through southwestern Marion County. It was designated the original route from Indianapolis to Martinsville, as described in this blog entry. This road will be discussed again a few paragraphs from now.

State Road 39: Another 1830s state road that was taken into the Indiana State Highway Commission’s custody in 1919. This road followed the old Brookville State Road from the National Road out of the county through New Palestine to Rushville and Brookville. The original end of that road, both the 1830s original and the 1919 state highway, is discussed here. The road would become, in October 1926, the other section of US 52 through Indianapolis. It would also eventually become the first state highway removed inside the I-465 loop in Marion County. And even then, it would be rerouted in the late 1990s to go the other way around the county.

That covers the 1919 highways. More would come to Marion County before 1923.

State Road 12: Originally, this road, north of Martinsville, was the old State Road 22 mentioned above. When a new SR 22 was created, the SR 12 number was continued from Martinsville to Indianapolis along the old Vincennes and Mooresville State Roads. This road, in October 1926, would become part of the new State Road 67.

State Road 15: While the southern route of the Michigan Road was State Road 6, the northern part, heading off to Logansport, was added later and given the number State Road 15. The entire route of the historic Michigan Road would never become a state highway, but major sections did…although late in the creation of the state highway system. With the Great Renumbering, this road became SR 29, and in 1951, redesignated, like its southern half, US 421.

State Road 22: Here we go again. State Road 22 was given to the route between Indianapolis and Paoli. In 1919, that included the route along the west bank of the White River from Martinsville to Indianapolis along the Mooresville Road. This was changed by 1923 to keep SR 22 on the east side of White River, where it followed the old Paoli State Road, and the Bluff Road, through Waverly to the south edge of downtown Indianapolis at Meridian and South Streets. This was one of the routes of the Dixie Highway through Indianapolis, and would later become part of SR 37 in 1926.

State Road 31: In 1920, when this road was originally created, it turned south to connect to the National Road west of Plainfield. It had followed the Rockville Road from Montezuma to Danville, then turned southeasterly to meet State Road 3. By 1923, the road was moved from what would later become part of what is now SR 39 to continuing on the Rockville Road into Marion County. State Road 31 would meet the National Road outside the city limits of Indianapolis at what is now the intersection of Holt Road and Washington Street. It would become US 36 before it was extended along the new section of what is now Rockville Road to the intersection at Eagle Creek with Washington Street.

State Road 37: One of two state road numbers that still served Indianapolis after the road numbers were changed in October 1926 (the other being State Road 31). The original State Road 37 left Marion County in a northeasterly direction on its way to Pendleton, Anderson and Muncie. Inside the city limits, the street name was Massachusetts Avenue. When it reached the city limits, the name of the road changed to Pendleton Pike. This still occurs today, with the name change at the old city limits at 38th Street. In October 1926, the number of this road would change to State Road 67.

There were two other major state roads in Marion County, but they weren’t part of the state highway system until after the Great Renumbering. One was the Crawfordsville State Road, part of the original Dixie Highway, connecting Indianapolis to Crawfordsville via Speedway, Clermont, Brownsburg, and half a dozen other towns. It would be added to the state highway system by 1929 as State Road 34. The number would change later to US 136.

The other road was the original Fort Wayne State Road, also known as the Noblesville State Road, but even more commonly called the Allisonville Road. It would be added to the state highway system in 1932 as State Road 13. Less than a decade later, its number would be changed to the more familiar State Road 37.
