'Corridor K' Improvements

​​​​​​​​​​​​​​Project Overview

The N.C. Department of Transportation is studying improvement options from Andrews to Stecoah in Cherokee and Graham Counties as part of a proposed project to provide the transportation infrastructure necessary for the well-being of local residents and regional traffic.

The upgrades would improve mobility and reliability between U.S. 129 in Robbinsville and the existing four-lane section on N.C. 28 at Stecoah.​

This region is known as Corridor K of the Appalachian Development Highway System – a network of road corridors established by Congress ​in 1965 to provide a safe, efficient transportation system for the Appalachian Region.

Corridor K extends from I-75 in Cleveland, Tennessee, to Dillsboro in Jackson County. Because of the challenges associated with the region's mountainous terrain and sensitive natural habitat, the proposed project is among the last of the Appalachian Development Highway System's corridors to be completed.
