State Route 186 (US 45 Bypass) Southern Extension

Madison County


Transportation projects are developed in four phases: Planning and Environmental, Design, Right-of-Way (ROW), and Construction. The following is a reflection of various aspects of these phases as they have occurred or will occur on the State Route 186 (US 45 Bypass) Southern Extension.

*Forecasted dates are subject to change.

In 2005, $4 million in federal funds became available for an extension of the existing US 45 Bypass, from Airways Boulevard to US 45 south of Jackson, as part of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) High Priority Projects (HPP) Program.   

In July 2007, the City of Jackson formally contacted TDOT requesting assistance from the Department's Local Program Development Office and permission to fund a Transportation Planning Report (TPR) and associated studies with HPP funds. In September 2007, TDOT agreed to match funds for the early portions of project development. The TPR was approved by TDOT in March 2009.

Because the project is proposed to be constructed with federal funds, a National Environmental Policy Act (NEPA) Environmental Assessment (EA) document is currently being prepared for the project. During the NEPA process, alignments will be developed within the corridors and environmental technical studies will be completed.
