Alcoa Highway: SR-115 (US-129) - Knox and Blount Counties

Project Description

On March 7, 2014, the Federal Highway Administration (FHWA) approved the Finding of No Significant Impact (FONSI) for this project, completing the process in compliance with the National Environmental Policy Act (NEPA).

State Route 115 (US 129/Alcoa Highway) is an urban principal arterial roadway, which is on the National Highway System. It is responsible for moving traffic efficiently throughout the region, particularly between the City of Alcoa and the City of Knoxville.

The proposed projects are intended to address transportation needs, which have been identified through coordination with local officials, agencies and the public. The purpose of the proposed projects is to:

  • Increase the capacity of SR-115 and the level of service
  • Correct roadway deficiencies and
  • Reduce crashes/improve safety

The roadway projects follow the existing alignment and consist of widening the existing roadway to six lanes (three lanes in each direction), except for the section between Singleton Station Road and Topside Road in Blount County (SR-333), where it will be widened to accommodate three travel lanes in each direction and two auxiliary lanes.  Seven interchanges and a center median barrier will be constructed or reconstructed along the route.  In Knox County there are two new interchanges (at Topside Road and Maloney Road) and two rebuilt interchanges (at SR-168/John Sevier Highway and Cherokee Trail). In Blount County there are three new interchanges (Topside Road/SR-333, Hillside Drive and Singleton Station Road).  Frontage/collector roads are also proposed at select locations along the route to provide access to properties and local roadways.
