State Route 115 (US 129/Alcoa Highway), from Woodson Drive to Cherokee Trail

Overview

The project along State Route 115 (US 129/Alcoa Highway), from Woodson Drive to Cherokee Trail, includes widening the existing roadway for approximately 1.6 miles.  Improvements follow the existing alignment and consist of widening the existing roadway to six lanes (three in each direction).  A modified interchange will be included at Cherokee Trail and the entrance to UT Medical Center.

This project is part of a larger effort to reconstruct and widen Alcoa Highway from State Route 35 (Hall Road) to Cherokee Trail in Blount and Knox Counties.  Due to the significant size of the overall project, the proposed improvements have been separated into seven smaller sections or phases.  To read more about the improvements for the corridor, visit https://www.tn.gov/tdot/projects/projects-region-1/sr115-us-129-alcoa-highway.html
