The Indiana Department of Transportation says preliminary work could begin this fall on upgrading U.S. 31 north of Indianapolis to interstate standards.
INDOT said Wednesday it has awarded a $141 million contract for freeway upgrades between 96th and 136th streets in Carmel to a joint venture between E&B Paving Inc. of Anderson and Gradex Inc. of Indianapolis.
The contract includes U.S. 31 interchange improvements at Interstate 465 and new roundabout interchanges at 106th, 116th, 131st and 136th streets.
INDOT says contractors will provide a general schedule later, but preliminary work could begin as early as this fall. All improvements for that section of the U.S. 31 upgrade are expected to be open to traffic by the end of 2015.
Upgrading or bypassing congested sections of U.S. 31, when completed, are expected to cut a half-hour off travel time between Indianapolis and South Bend.
