US 31 Closure

US 31 closure between Old Meridian Street and 136th Street

Announced in 2012, INDOT planned to close US 31 between Old Meridian Street and 136th Street to accelerate the construction of an overpass at 126th Street/Carmel Drive and roundabout interchanges at 131st Street/Main Street and 136th Street. Early utility relocations and cleared right-of-way allowed the previously planned closure of US 31 between Old Meridian Street and 136th Street in Carmel to move up one year.

Crews closed US 31 between Old Meridian and 136th streets on April 4, 2014, and the road is expected to reopen before Thanksgiving.

Access to businesses and hospitals remains open during the US 31 closure via local roads. See below for hospital access maps.

Detour route

Note: Beginning in August 2014, Carmel Police will begin distributing tickets to drivers of large trucks who use local streets instead of following the signed detour route to Keystone Parkway during the US 31 closure. Drivers making local deliveries are exempt.

Since the closure started, INDOT is monitoring traffic patterns and congestion. Necessary signal timing adjustments will be made once traffic patterns stabilize.

The official detour route is Keystone Parkway. Pennsylvania and Illinois streets serve as alternate routes for local access. Click the image below for an enlarged view of the detour route.

Cross traffic access during the US 31 closure

136th Street

During the US 31 closure, motorists are able to cross US 31 at 136th Street at all times, and access to St. Vincent Carmel remains available. Motorists are able to access 136th Street from southbound US 31, and access is available to northbound US 31 from 136th Street.

126th Street/Carmel Drive

Access across US 31 at 126th Street/Carmel Drive closed on Sept. 12 to begin construction of the bridge over US 31. Upon completion of construction, no direct access to/from US 31 will be available at this location.

Old Meridian Street

Motorists are able to access Old Meridian Street from northbound US 31 through the duration of the US 31 closure. Old Meridian Street allows free-flowing access to southbound US 31.

131st Street/Main Street

Access across US 31 at 131st Street/Main Street reopened on Sept. 12. One lane of traffic is open eastbound and westbound as crews continue work on the roundabout interchange. Motorists should note that 131st Street/Main Street is closed east of Pennsylvania Street for the City of Carmel’s Main Street Improvement project. Therefore, motorists traveling eastbound across the new 131st Street/Main Street bridge must turn onto Pennsylvania Street. Direct access to/from US 31 via the new 131st Street/Main Street interchange will not be available until the US 31 closure ends later this fall (expected before Thanksgiving).

Benefits of closing US 31 in 2014

Closing the roadway in 2014 provides benefits to motorists and construction crews, including:

  • A shortened closure duration to approximately eight months, compared to approximately ten months if the closure were to happen in 2015
  • Improved work zone safety while elevation changes are made for new bridges at 126th Street/Carmel Drive, 131st Street/Main Street and 136th Street
  • The removal of traffic signals from eight miles of US 31 by December 2014
  • Allows INDOT to fulfill its commitment to open the US 31 freeway to traffic by December 2015
