Project Description:  The project included the complete reconstruction of the system to system interchange at I-465 and I-74.  It also reconstructed the interchange access from I-465 to Brookville Road and Shadeland Avenue.  The interchange configuration involved extensive coordination with geotechnical to determine the most cost-effective solutions for the fly-over ramps.  It was determined in that longer bridges were more economical than walls due to the existing soil conditions.  Maintenance of Traffic was a major component of the design due to the urban environment.  Additionally, detention and lift station designs were completed as part of the project to facilitate drainage.

Approximate Project Cost:  $74,000,000

Breadth of Services Provided:  Regulatory Permit Applications, Roadway Design, and Bridge Design
