US 31 additional travel lanes

US 31 Added Travel Lanes

The US 31 Added Travel Lanes Improvement Project included upgrading US 31 to a fully controlled access freeway consisting of nine new interchanges and an additional five over/under passes. The project upgraded US 31 to freeway standards from I-465, at the Marion-Hamilton county line, through Carmel, to 216th St. in Westfield, a distance of approximately 12.5 miles.

IEI’s responsibility on the project included the design of the new 191st Street Interchange and the storm water management and drainage design for the 3.5 mile section of the freeway. IEI’s storm water management scope includes a location drainage study of 8.3 square miles of watershed, field data collection, analysis of flooding problem areas, design of ditches and channels, 10 major culverts for crossing streams and storm water detention. Detention is designed to detain the 50-year post-development peak runoff and release it at the 10-year pre-development peak runoff rate.

IEI also performed Hydrologic Engineering Center’s River Analysis System (HEC RAS) hydraulic modeling, including scour evaluations, for the Jones Creek and Lindley Creek watersheds and developing hydraulic reports. IEI applied for the IDNR Permit for the Jones Creek and Lindley Creek bridge reconstruction.
