US 64 (Corridor K)

Polk County

TDOT released its 10-Year Project Plan on December 18. Project information included on this webpage is subject to change.

A series of projects have been identified for US 64, commonly referred to as Corridor K. The proposed spot improvements would cover approximately 20 miles of the corridor, from west of the Ocoee River to State Route (SR) 68 near Ducktown. The purpose of the proposed projects is to improve the safety and efficiency of the route, as well as regional mobility and connectivity. The improvements would preserve environmental quality and support economic development.

Proposed design improvements include roadway widening, guardrail installation, and curve correction, as well as intersection and recreational access improvements. Proposed rockfall mitigation includes rock excavation and catch fence installation. Additionally, a bridge-and-tunnel option is being considered on the south end of the project area. Due to the size of the proposed improvements, TDOT has split the project into several segments.

One segment, from west of Welcome Valley Road to east of the bridge over Cloud Branch, is identified for funding in TDOT's 10-Year Project Plan, with construction scheduled for Fiscal Year 2025.

Current Status: TDOT is currently working with the Appalachian Regional Commission (ARC) on a targeted approach. Both financial and environmental challenges at the federal, state and local levels have delayed the development of the corridor.

Estimated construction start: Fiscal Year 2025

Estimated completion: TBD

History and Background

Corridor K is part of the Appalachian Development Highway System (ADHS), which stretches 127 miles between Cleveland, Tennessee, and Dillsboro, North Carolina. The section of Corridor K, known as the Ocoee River Gorge section, includes 20 miles of US 64 between the Ocoee River and Ducktown.

The Ocoee River Gorge section of Corridor K is part of the Ocoee Scenic Byway and is a Tennessee Scenic Parkway. It is also the only east-west arterial in the region and serves through, local, and recreational traffic.

The existing two-lane highway does not meet current design standards. The corridor contains numerous roadway deficiencies and safety issues with limited shoulder widths, lack of guardrails, inadequate sight distance, and sharp curves. The windy, rocky terrain also presents a major barrier to development with increased susceptibility to rockslides and lack of convenient detours.
