Interstate 75 Corridor Feasibility Study

The I-75 Corridor Feasibility Study is complete and available online in the I-75 Corridor Study Library.

As identified in the Tennessee Long-Range Transportation Plan, known as PLAN Go, the strategic highway system includes routes the state considers critical to statewide mobility and regional connectivity. The transportation plan classified routes needing improvement, while protecting and maximizing capacity over the next decade. Interstate 75 is part of this system and classification.

Completed in 2009, the I-75 Corridor Feasibility Study identified short- and long-term solutions for improving problem spots along the entire corridor. The study also investigated a range of multi-modal solutions to address future travel demands, with emphases on managing congestion, improving safety, maximizing the potential for freight diversion, and preserving/enhancing the corridor's economic benefits.

The study area for the I-75 Corridor Feasibility Study extends from the Georgia state line in Chattanooga to the Kentucky state line, a distance of approximately 160 miles. The corridor includes I-75, parallel Class I railroads, and parallel major arterial routes. The corridor traverses seven counties, three Rural Planning Organization (RPO) areas, and three Metropolitan Planning Organization (MPO) areas. Cities along the route, such as Chattanooga, Cleveland, Athens, and Knoxville, depend on this corridor for commerce, tourism, and daily commuting.

TDOT is dedicated to managing congestion and improving safety along the I-75 corridor. Both technical analysis and input from local officials and individuals were used to provide as much data as possible for the corridor study. The results of the study provided a prioritized listing of potential multi-modal projects that can be considered by TDOT or by local planning organizations.
