Interstates 40 and 81 Corridor Feasibility Study (2008)
The I-40/I-81 Corridor Feasibility Study is complete and available online in the I-40/I-81 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 40/Interstate 81 is part of this system and classification.
Completed in 2008, the I-40/I-81 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-40/I-81 Corridor Feasibility Study extends from Bristol to Memphis, a distance of about 550 miles, and traverses 27 of state’s 95 counties. This area includes 9 of the 12 Rural Planning Organizations (RPOs) and 8 of the 11 Metropolitan Planning Organizations (MPOs) / Transportation Planning Organizations (TPOs) statewide.
TDOT is dedicated to managing congestion and improving safety along the I-40/I-81 corridor. Both technical analysis and input from local officials and individuals was used to provide as much data as possible for the corridor study.
