US 64 Corridor K

Polk County

Corridor K Tunnel Preliminary Evaluation (.pdf)


US 64/Corridor K is a route on the Appalachian Development Highway System, which starts at I-75 near Cleveland, Tennessee, and ends near Dillsboro, North Carolina. TDOT is proposing to make improvements along the corridor, specifically the section of the road from west of the Ocoee River to SR 68 near Ducktown. This portion of Corridor K is part of the Ocoee Scenic Byway, which was designated as the nation’s first National Forest Scenic Byway. It is also a Tennessee Scenic Parkway.

Within the project study area, Corridor K has numerous transportation problems, including roadway deficiencies (e.g., lack of shoulders and guardrails, susceptibility to rockslides) and safety issues (e.g., inadequate sight distance, sharp curves). The proposed project is needed to address these issues and facilitate a safer and more reliable and efficient east-west transportation route.

A Draft Environmental Impact Statement (DEIS) is being prepared in accordance with federal requirements.  The DEIS will provide comprehensive information about the purpose and need for the project, proposed plans, and potential environmental, social, and economic effects.

The DEIS is scheduled to be available for review in Winter 2015.

DEIS Alternatives

Five build alternatives have been identified to be studied in detail in the DEIS (also referred to as the DEIS alternatives).

  • Alternative 2 – Improve Existing US 64
  • Alternative 4 –New Location/Improve Existing US 64
  • Alternative 5 – New Location/Improve Existing US 64
  • Alternative 8A – New Location/Improve Existing US 64
  • Alternative 9 – New Location/Improve Existing US 64 (with or without Tunnel)

A No-Build Alternative will also be evaluated. These alternatives were determined following intensive coordination with the regulatory/resource agencies and through public input. The DEIS will include detailed descriptions of each of these alternatives and the potential impacts that could result. Once completed, the DEIS will be made available for public review and comment.
