Interstate 75 Interchange at Interstate 24

Hamilton County

Timeline

Transportation projects are developed in four phases: Planning and Environmental, Design, Right-of-Way (ROW), and Construction. In an effort to expedite project delivery, the Interstate 75 Interchange at Interstate 24 modifications will be completed under a Design-Build contract. The Design-Build project delivery method combines all or some portions of the design and construction phases of a project - including design, regulatory permit approvals, utility relocation, and construction – into a single contract.

The following is a reflection of various aspects of the project phases as they have occurred or will occur for the planned I-75/I-24 Interchange improvements.

Contract Award

On Friday, December 21, 2018, TDOT officially announced the award of the contract for the I‑75/I‑24 interchange modification project to C.W. Matthews Contracting Co. Inc. at a cost of $132,644,398.00.

Using the Design-Build project delivery method, design and construction will be completed in less than three years.

Following the contract award, the design will be finalized and the necessary permits acquired. In spring 2019, geotechnical improvements will begin in the project area, with construction expected in late fall 2019. Once construction begins, every effort will be made to minimize impacts to drivers.

The I-75/I-24 interchange modification project is one of 962 critical transportation projects included in the 2017 IMPROVE Act legislation. For more information on IMPROVE Act projects, visit the Statewide Project Overview Tracker, or SPOT.
