Project Overview

Level Up 31 is the interchange modification project for US 31 and I-465 in Hamilton County. It includes the modification of the I-465/US 31 north interchange, seven bridge deck overlays, and related work on US 31 from I-465 to 116th Street in Carmel. The project will increase capacity for west to north and east to north movements to create better traffic flow and enhance safety.
