All northbound and southbound lanes of US 31 (Meridian Street) between 136th Street and Old Meridian Street will be closed for construction starting this week (April 7, 2014). The project is expected to finish up by November.

Plan now for alternate routes, delays, and detours in the area.

See a map here, and get project updates.

The posted detour will be along Keystone Avenue and I-465 with access to local businesses and medical facilities made through local streets. Medical patients should contact doctors and facilities to find the best way to access those locations. Traffic will be able to cross 136th Street for access to St. Vincent Hospital during the construction.

US 31 will be closed throughout the spring and summer with an expectation that the work will be completed and the road open by Thanksgiving.

On or after Monday, April 7, crews expect to begin shifting all lanes of US 31 to the east side of the roadway between 169th Street and SR 38. Once this traffic shift is complete, crews will begin construction on the west side of US 31 through the remainder of 2014 and the following restrictions will be in place:

•Southbound US 31 reduced to one lane between SR 38 and SR 32

•Northbound US 31 reduced to one lane between 181st Street and SR 38

•Access to/from 203rd Street at US 31 permanently removed

Once the traffic shift between 169th Street and SR 38 begins, left turns to/from US 31 will only be permitted at the following cross-streets:

•181st Street/Hoover Street

•196th Street

•SR 32

•169th Street

As part of the traffic shift on or after April 7, INDOT plans to install a new flashing yellow left-turn signal on US 31 at the temporary traffic signal at 196th Street. This type of turn signal allows left-turning traffic to yield the right-of-way to oncoming traffic and pedestrians and turn when a suitable gap is available.

National research has shown that the flashing yellow signal is more intuitive for drivers, resulting in fewer crashes and the more efficient movement of traffic at an intersection. The signals are being introduced nationwide and have been adopted by most states.
