West Knoxville Corridor

The Tennessee Department of Transportation (TDOT) plans to study, design, and prioritize improvements to the Interstate 40/Interstate 75 corridor west of Knoxville, from the I-40/I-75 Interchange in Loudon County to the I-640 Interchange just west of downtown. TDOT’s 10-Year Project Plan, released in December 2023, identified funding for several projects along the corridor. Instead of treating those projects as isolated segments, TDOT plans to develop a holistic strategy for improving the corridor as a whole. 

During the next 18 to 24 months, TDOT will invest in preliminary engineering to determine what corridor improvements need to be made to increase throughput and reduce travel times. Preliminary engineering will focus on significant enhancements to the 17-mile corridor where I-40 and I-75 are joined and includes the interchanges at Watt Road and Campbell Station Road, both weigh stations, and the potential for future Choice Lanes. The work will include data collection, an assessment of previous studies, an existing conditions analysis of both engineering and environmental features, a traffic analysis, and an operations assessment.
