Terre Haute. The building of the Terre Haute Airport along SR 42 east of the city helped create one of the shortest state roads in Indiana history: SR 342. And given that part of its history includes a span of existence of less than a decade, it could have gone down as one of the shortest lived state roads in Indiana, as well.
The Terre Haute airport (Hulman Field) began to appear on Indiana Official maps in 1946. The airport was located east of SR 46 and west of Chamberlain Street on SR 42. The red circular object on the 1946 map to the right shows the location of the air field. Also notice, at the time, SR 46 does not continue to US 40 as it does today (actually, the road IS US 40 today, but I digress). SR 46 either ends at, or multiplexes with, SR 42, which enters Terre Haute as Poplar Street.
Between 1953 and 1956 (I am looking for maps to nail the exact date down), a new state road was created: SR 342. It was a very short road, only about one half mile long. A notice in the Terre Haute Tribune of 29 July 1964 states that “the Bituminous Materials Co., 444 S. 6th St., was awarded a $116,893.50 contract to repave 5.5 miles of State Road 42 from State Road 342 east to 1.96 miles east of the Clay County line, and State Road 342 south from State Road 42 for a half mile.”
By 1959, the official map showed that Terre Haute had annexed the territory out to the airport along SR 42 (SR 46), with SR 342 being the eastern edge of the city. The 1959 also shows that SR 342 might have moved to the east to be along Chamberlain Street. Looking at a current map, this makes sense. But until 1959, it looked like SR 342 connected to what is now the terminal at the airport.
By 1963, SR 342 would be removed from state official maps. This means that this state road had existed less than a decade. Again, looking at a current map of the area, the former SR 342 does, or more to the point did, connect to both the Indiana Air National Guard and the Indiana Wing Civil Air Patrol. That would, in theory, warrant a state road designation. Or would have at that time.
As an aside, the part of Chamberlain Street south of SR 42 is closed, being blocked by a large barricade. And the road being narrow past that barricade. Yet someone thought far enough ahead to make sure that this ~100 feet long road had a brand new stop sign (installed in 2014 by INDOT). Want to see Google’s image of it, click the link here. There is also another abandoned road just to the east of this location. SR 42 turns to the southeast to connect to a roundabout that allows access to the IANG/Civil Air Patrol area, but a quick glance at a map shows an old road that connected in a straight east/west line to SR 42.
And just when you thought it was over, 1969 shows the return of SR 342. First mention of this return of SR 342 was in the Terre Haute Tribune of 29 March 1967. The legal notice of condemnation of land was published, mentioning that the land was being condemned for use by the United States Department of the Air Force, and that one boundary of said land was the “west right-of-way line of the proposed State Road 342.” This second incarnation of SR 342 would exist around 45 to 50 years, being removed in the mid-2010s. With the rerouting of the entrance to the Indiana Air National Guard facility, the old road was blocked off and the new road never got the state road designation.
In the end, SR 342 existed from 1956 to 1963, and from 1969 to roughly 2015.
