Indiana Highway Ends

SR 431

State Road 431 The most recent route of SR 431 went from US 31 in Carmel south to I-465 in northern Indianapolis. The route was decommissioned and turned over to the City of Carmel. Under the control of Carmel, unlike while under the control INDOT, is building a series of interesting interchanges. This section was a divided highway with controlled access though it had more than its share of stoplights causing long travel times. This section used to go to old SR 37 in Indianapolis near the state fairgrounds. For a long while, SR 431 had a single long section going from Carmel to Greenwood, but it eventually was broken up into two sections. The resulting southern SR 431 southern section went from Indianapolis to Greenwood. Background: At one time, before the building of the SR 431 on Keystone Avenue, SR 431 ran from the connection of Range Line Road and US 31 ( near current SR 431 and US 31 come together) to what is now Meridian Street and Westfield Blvd on the northside. All of the sections of SR 431 that existed originally were US 31. The northern section was rerouted mainly due to narrow space in Broad Ripple. Westfield Blvd (formerly SR 1, US 31 and SR 431) is a nice drive, but is very narrow. The southern section became SR 431 in 1948 with the building of the US 31 "bypass". The City of Greenwood, whose downtown area is at Madison and Main, had buildings built right up to the sidewalk. There was no way to expand the road there, so the state just bypassed it. The photos below show the new post-INDOT interchanges on what once was SR 431.
