## State Road 431

The former State Road 431, now simply Keystone Parkway, remains a busy route connecting U.S. Route 31 with Interstate 465 at Exit 33. It passes through the Indianapolis suburb of Carmel, allowing traffic on U.S. 31 north of Carmel a shorter route to I-465 and the east side of Indianapolis.

Keystone Avenue to S.R. 37 at Fall Creek Parkway, North Drive in Indianapolis.
State Road 431 was officially decommissioned on October 19, 2007, with the portions north of 96th Street being turned over to the city of Carmel. Carmel Mayor James Brainard immediately proposed banning heavy trucks from the route, the Hamilton County portions of which lies within his city's corporate limits. He also pushed for a plan to build six roundabout-style interchanges on Keystone, built 2009–2010, in lieu of widening it to at least six travel lanes throughout.
Further south in Marion County, a former southern portion of S.R. 431 extended south along Madison Avenue from the south side of Indianapolis through Greenwood. Madison Avenue, which was the original routing of U.S. 31 on Indy's south side, does not have an interchange with I-465, however. The northern terminus of this section was at Madison's intersection with East Street, which used to carry U.S. 31 to the south.
