Indiana has always been known as the “Crossroads of America.” For the most part, highways connecting Indiana to the rest of the United States have been through routes. But in the beginning of the US highway system (i.e. that on 1 October 1926, when it came to life in Indiana), there was one that ended near the western edge of the city of Indianapolis: US 36.
Let’s step back quite a bit before October 1926. What is now US 36 began life as the Indianapolis-Rockville State Road, basically a wagon trail connecting the capital city to the county seat of Parke County. Along the way, it also connected to the county seat of Hendricks County, Danville. What is currently US 36 west of Hendricks County is part of the original road. However, there were several sections that were straightened out by the state over the years.
When the Auto Route era started, the Rockville Road (now a series of county gravel roads) was included as part of the Pikes Peak Ocean to Ocean Highway. I have copies of maps spanning 1918 to 1920 showing this. Also, the Federal Highway Administration shows this in a series of strip maps. This link shows the section from Indianapolis to Chrisman, IL.: https://www.fhwa.dot.gov/infrastructure/ppmap05.cfm
(East of Indianapolis, at this time, the PPOO followed the National Old Trails Road, including the Eaton Cut-off, towards Dayton, OH.)
By 1923, the PPOO had moved, according to the website http://www.ppoo.org. The 1923 route was moved to come into Indiana along what was original SR 33 across Indiana. OSR 33 became SR 34 (and, later, US 136) from the Illinois-Indiana state line to Crawfordsville, then became SR 32 through Lebanon, Noblesville, Anderson, Muncie and Winchester to the Indiana-Ohio State Line at Union City.
The old PPOO, Rockville Road, by 1923, became SR 31 from SR 10 (future SR 63) to its connection with OSR 3 (the National Road) at what is now Holt Road and Washington Street. (To use the original road, either east or west, requires a journey through a Steak ‘n Shake parking lot. This is a fact that I have repeatedly used throughout the existence of both this blog and the Facebook group that spawned it.)

The “Great Renumbering” is about to occur in Indiana.
This snippet shows the pending US 36 description.
With the Great Renumbering of 1 October 1926, US highways were added to the state, and US 36 was among them. The route of the original PPOO, the one that became SR 31, became the route of US 36. However, the section that connected Chrisman, IL, to SR 63 was incomplete and under construction. Since, at the time, it had not been a section of the state highway system, the ISHC was playing catch up to get it up to speed. Also, at the time, the original US 36 connected to the National Road at the above mentioned Steak ‘n Shake (i.e. Washington Street and Holt Road). Holt Road originally came from the south and ended at this intersection. It would be many years later, even after the removal of US 36 to I-465’s south leg, that Holt Road would be built to the dead end (more or less) that it is today.

That’s right. US 36 ended in Indianapolis. It followed US 40 downtown, but most maps I have seen from the era aren’t detailed enough to show that. The only proof I have of that is a picture from the Indianapolis News of 28 April 1928. It shows a “highway totem pole” at the corner of West Washington Street and Meridian Street. (That point was a multiplex consisting, in the order the state put them, US 40, US 52, US 36 and SR 29. US 36 stayed in that status for at least the next five years.
I am doing further research into the location of US 36 along the Rockville Road/Rockville Avenue corridor. For the longest time, the section that is Rockville Road now from Washington Street to what is called Rockville Avenue didn’t exist. As a matter of fact, official Indiana State Highway Commission maps show that Rockville Avenue was US 36 all the way up to 1930. What is now Rockville Road east of Rockville Avenue, apparently was the dream of the E. L. Cothrell Realty Company. In 1925, they started building a new neighborhood, which could be reached by going “out West Washington street to the 3500 block.” By 1927, it would finally list the Rockville Road as part of the marketing, as all houses would front either Creston (the name of the development) or Rockville. As shown in the map below, it would seem that the “new” Rockville Road was built expressly for the Creston development.

By 1932, the extension of US 36 started. The signs marking US 36 were extended along what was then SR 67 (Massachusetts Avenue/Pendleton Pike) and, when near Pendleton, along SR 9/SR 67 to Huntsville, where a road was authorized to connect Huntsville to Ohio SR 200 at the state line west of Palestine, OH. At that time, the designation US 36 entered Ohio as the cross state line continuation of SR 32 at Union City. That US 36 connected Union City to Greenville, OH.

By 1933, the state had under its jurisdiction the complete route that would be US 36 in Indiana. There were some changes along the way, with sections moved and bypassed here and there. The first bypass was being built in 1935, which would be a replacement for the section through downtown Indianapolis. By 1936, US 36, and SR 67, would be turned north along SR 29 (later US 421, today West Street/Martin Luther King Jr. Street) to 38th Street. Then east along 38th Street to its connection to Pendleton Pike. (BTW – officially, this is the beginning of what is now called Pendleton Pike. 38th Street, at the time, was the edge of the city most of the way. As such, inside 38th Street, the old Pendleton Pike is called Massachusetts Avenue. That will be the subject of a later post…I promise.)
The major bypass would also be in Marion County. In the late 1970’s, the Indiana Highway Department, and its successor, the Indiana Department of Transportation, would start handing state roads back to the counties. In Marion County, as far as US 36 was concerned, that would mean that the designation US 36 would turn onto I-465, using the road from Rockville Road on the west side, along the south leg, to Pendleton Pike on the northeast side.
