About the Project

The New US 31 Hamilton County project will upgrade US 31 to freeway standards from I-465 at the Marion-Hamilton County line, through Carmel and Westfield to State Road 38. Upgrading the 13 miles of existing highway between I-465 and SR 38 to Federal freeway standards will be, in terms of dollars, the largest and most aggressive road project ever attempted in Hamilton County. The New US 31 Hamilton County project is intended to reduce congestion, improve safety and provide continuity of commerce and regional travel for a US highway that stretches from Michigan to Alabama. Work on three congested sections of US 31 is underway, and when completed, travel time between Indianapolis and South Bend is expected to decrease by about 30 minutes. Construction began in 2011 and, with the accelerted schedule, the entire corridor is expected to open to traffic between I-465 and SR 38 by December 2015.
