The route is 7.5 miles (12.1 km) long and is located entirely in Bradley County.

Approximately one mile later, the road turns sharp east, crossing Candies Creek Ridge a short distance later before coming to an intersection with Old Lower River Road, the former route of SR 308, almost two miles later.

Approximately one mile later, it meets its eastern terminus in southern Charleston with US 11 (North Lee Highway/Hiwassee Street/SR 2).

[1][3] The route originally continued to Charleston along the Hiwassee on what is now Old Lower River Road.

[5] For this reason, part of the highway was moved to its current location in the late 1960s and early 1970s when the interstate was built.
