1920-1960: Adams County Roads

Today, I want to start a series, with a lot of maps, that shows the evolution of the state highway system in each county from 1920 to 1960. Starting with the first county, alphabetically.

First, let’s start with the creation of Adams County. Dated 7 February 1835, “formation by statute, effective on publication. The formation affected territory attached to Allen and Randolph counties. Adams was organized under an act of January 23, 1836, effective March 1, 1836.” The county was legally described as follows: “Commencing at the south east corner of Allen county, thence west with the southerly border of said county, to the north east corner of section five in township twenty eight range thirteen, thence south with the section lines to the township line between townships twenty four and twenty five, thence east with the said township line to the eastern boundary line of the state, thence north with the state line to the place of beginning.” This information was included on page 44 of the Laws of Indiana, 1834-35.

The county seat was also included in my source: “Commissioners appointed under the organization act reported to county commissioners on May 18, 1836, their choice of a site in section 3, township 27 north, range 14 east of the second principal meridian, where Decatur now stands.”

When the state highway system was officially created in 1919, state roads were being all over Indiana. The major purpose of the system was to connect to each county seat. To that purpose, the first of the new state roads to be added in Adams County was known as State Road 21. It was laid out, as shown on the 1920 map to the right, in a not so straight path connecting Geneva, Berne, Monroe and Decatur. From Decatur, it aimed off towards Fort Wayne.

I have access, through the state library online, to two different maps from 1923. The state did two things in that year. First, it issued the first official highway map since 1920, and two, the reason it was issued was due to the fact that the Indiana State Highway Commission was going through what I have referred to as the “Little Renumbering.” The other map, one that I use quite a bit, lists the state roads prior to the renumbering.

The non-official map included the state road numbers in use at the time, as well as the Auto Trails that were in place. That map uses circles with numbers for the state roads. As shown on the map to the right, state road 21 is still the only state road in the county. But it was also known as the “Ohio, Indiana and Michigan Way” Auto Trail.

The other road marked on that map, shown as “GG” is the “Huntington, Manitou, Culver Trail.” While the title cities were on the trail, it did connect to someplace in Ohio and possibly beyond. I am trying to find any information I can to figure it out. At the west end, the road went at least as far as Chicago.

The first renumbering of state highways in September 1923 didn’t affect Adams County at all. The former state road 21 remained the same afterwards.

1926 Indiana Official State Highway Map

The number of state roads in Adams County doubled with the Great Renumbering on 1 October 1926. The new SR 16 would cross through the county west to east, connecting Decatur to Huntington. What is now County Road 600 North east of Decatur was, at that time, SR 16. The road ended abruptly at the state line. There was a state road in Ohio (Ohio SR 109) that ended at the state line, as well. But it was one mile north of the new SR 16.

The old state road 21 would become part of the United States Highway system, given the number 27. The original route of OSR 21 was still followed across Adams County as US 27, including the curvy route from Geneva to Berne. Today, that route is known as County Road 150 West.

By 1930, State Road 16 was moved one mile north east of Decatur, to connect to what was Ohio State Road 17 (formerly Ohio SR 109). (Ohio changed state road numbers quite a bit…and have done that since.)

1931 brought another state road to Adams County: SR 118. But there were also authorized additions to the state highway system crossing from Bluffton, in Wells County, through Monroe, to the Ohio state line near Willshire, Ohio. Another authorized addition, also starting near Willshire, crossed northwest bound to end in Decatur.

SR 118 started at SR 5 along the Huntington-Wells County line, due east through Berne to end at a county road at the Indiana-Ohio state line in Mercer County, Ohio.

The two authorized additions to the state highway system were given designations in 1932. The east-west route through Monroe was called SR 124. The northwest/southeast route was made a daughter of US 27, given the name SR 527.

1933 made another change to the state highway numbers in Adams County. State Road 16 would be removed from the county, with the road redesignated part of the United States Highway system as US 224.

1935 Indiana Official State Highway Map

Changes kept occurring in the connections to Adams County. In 1935, an authorized addition to the highway system was added to maps as SR 101. This road would start at the new US 224 (old SR 16), going north toward Monroeville in Allen County.

Another state road to US highway change was made in 1938, when the US 33 designation replaced SR 527.

By 1941, a US 27 Decatur bypass, moving outside the town to the west, would be in operation. US 33 still traversed Decatur, meeting US 27 north of the town. The new US 27 would also bypass Monmouth to the west, while US 33 still used the old route of US 27 to northwest of Monmouth.

Also that year, another state road was added to Adams County. That road, starting in Geneva and working its way west, north, and northwest towards Bluffton. It would be designated SR 116.

Changes continued during World War II…but mainly with just marking the roads. According to the Indiana Official State Highway map of 1945, SR 101 was extended in its line from US 224 to SR 124. SR 116 was extended through Geneva, down to New Corydon and along the south county line.

Along the way, US 33 would connect to US 224, then “travel over” US 224 to US 27, where US 27 and US 33 would join forces again like they did when US 33 was created.

No changes were made for the next nearly decade and a half. By 1959, SR 101 between US 224 and SR 124 was moved to the east one mile. to its current location.

I hope that you like this possible series of articles. I look forward to your opinions and comments about it.
