U.S. 31 to southbound Keystone closes April 9


The U.S. 31 ramp to southbound Keystone Parkway will close on or after Monday, April 9 to rebuild a bridge over Cool Creek and the Hagan-Burke Trail as part of U.S. 31 Hamilton County construction. Southbound traffic will be detoured over U.S. 31 and I-465 for approximately 90 days.

Earlier this month, the state announced its intent to speed up U.S. 31 Hamilton County construction and open the project to traffic three years earlier than expected. The Indiana Department of Transportation (INDOT) will provide updated design, schedule and construction information at an open house on Thursday, March 29. Community members will have the opportunity to speak one-on-one with project team members. A presentation is scheduled for 6 p.m.

On or after Wednesday, April 11, both directions of U.S. 31 will share the northbound lanes between 136th Street and 151st Street.
