I-465 and I-70, Marion County East Side, A Pictorial History

Today, I want to take a look at the interchange between Interstates 70 and 465 on the east side of Marion County…in pictorial form. This history will cover from 1962 to 1993, with what aerial photographs are available from MapIndy, the official mapping application of Indianapolis/Marion County. It will also cover the interchange between Interstate 70 and Shadeland Avenue, which was SR 100 before, and for some time after, the building of its replacement, I-465.

Two of the constrictions at the location of this interchange were both 21st Street and Franklin Road. Franklin Road had been in place since it was created as the Noblesville-Franklin State Road early in the state’s history. As you can tell from the photos, the routing of Franklin Road was changed between 21st Street and around 25th Street. The original routing of the road is still in place, but contains two dead end sections at the interstate.

21st Street has been around for a whole lot of years, as well. Maps show that it was added to the county sometime between 1870 and 1889. In 1889, there was a toll house for the Pleasant Run Pike on the northwest corner of 21st Street and Shadeland Avenue. From what I can tell, the only part of the road that was a toll road was from Arlington Avenue to Mitthoeffer Road. Today, 21st Street can be followed from Massachusetts Avenue at the Bee Line (Big Four – Conrail – CSX) Railroad to a point just northwest of Charlottesville.

The ramp from I-70 West to I-465 South was under construction in 1978, and would be completed in 1979. Prior to this, that traffic movement was handled by a loop ramp, as the interchange was originally built as a 3/4 cloverleaf. By 1993, the current collector/distributor system connecting Shadeland Avenue to both I-70 and I-465 was completed.

The ramps to Shadeland Avenue have always been a very tight fit into the area allowed.
