Interchange Modifications at I-465 and I-74
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
