State Route 115 (US 129) Alcoa Highway Hall Road to Tyson Boulevard InterchangeBlount County
The project along State Route 115 (US 129/Alcoa Highway), from State Route 35 (Hall Road) to the proposed interchange at Tyson Boulevard in Blount County, includes realignment and reconstruction for approximately 1.5 miles. A new interchange will provide access to McGhee Tyson West Aviation area, Hunt Road, and the City of Alcoa’s planned development, Springbrook Farm.
This project is part of a larger effort to reconstruct and widen Alcoa Highway from 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 all improvements for the corridor, visit the Alcoa Highway project website.
Purpose and Need
Alcoa Highway is a major connection between the City of Knoxville and the Cities of Alcoa and Maryville, as well as providing a route to McGhee Tyson Airport and the Great Smoky Mountains National Park.
The proposed improvements for the heavily-traveled corridor are intended to increase capacity, correct roadway deficiencies, and reduce crashes in order to address transportation needs by improving the safety, efficiency, and operation of the roadway.
Alcoa Highway from SR 35 (Hall Road) to SR 335 (Hunt Road) is one of three sections that will realign the corridor, referred to as Relocated Alcoa Highway, and one of seven sections that will improve the corridor in Blount and Knox Counties. (See Alcoa Highway project website)
The section between Hall Road and Hunt Road will be reconstructed, shifting the alignment to the east of the existing roadway. The new alignment will be a four-lane, controlled-access facility, allowing for two lanes in each direction with no signals or intersections.
A new interchange will provide access to McGhee Tyson West Aviation area, Hunt Road, and the City of Alcoa’s planned development, Springbrook Farm. Traffic traveling from these areas, including Hunt Road, will access both the Relocated Alcoa Highway and the existing Alcoa Highway by way of the newly constructed Tyson Boulevard interchange.
The Hunt Road overpass bridge will be reconstructed in the same footprint of the current structure.
A new pedestrian greenway will be constructed along the new Hunt Road bridge, connecting Mills Street, Hunt Road, and Ambrose Street.
The reconstructed section of Alcoa Highway, between Hall Road and Hunt Road, will connect with the existing Alcoa Highway, north of Hunt Road. Once all Relocated Alcoa Highway sections are complete, the new facility will separate local traffic from commuter through-traffic, while the existing facility, referred to as the Motor Mile, will continue to provide access to local businesses.
