State Route 115 (US 129) Alcoa Highway Maloney Road to Woodson DriveKnox County
On Monday, September 11, 2017, contract crews will begin work on the collector road at Maloney Road. Motorists should expect to see detours to Ginn Drive during construction.
The project along State Route 115 (US 129/Alcoa Highway), from south of Maloney Road to Woodson Drive in Knox County, includes widening the roadway for approximately 1.4 miles. Improvements follow the existing alignment and consist of widening the existing roadway to six lanes (three lanes in each direction). A new interchange will be also constructed at Maloney Road as part of the project.
The improvements currently under construction are part of a larger effort to widen Alcoa Highway in Blount and Knox Counties. Due to the significant size of the overall project, the proposed improvements have been separated into four smaller sections or phases.

Purpose and Need
SR 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 along the corridor are intended to address transportation needs, which have been identified through coordination with local officials, agencies and the public. Those transportation needs are as follows:
- Increase the capacity of Alcoa Highway and the level of service
- Correct roadway deficiencies
- Reduce crashes/improve safety
The portion of Alcoa Highway from Maloney Road to Woodson Drive is Phase 1 of 4 planned for the corridor. Improvements in this phase will widen the roadway to three lanes in each direction, separated by a median barrier wall. Construction will include 10 retaining walls and three bridges to provide connection for new collector roads that parallel the highway. Roundabouts will be installed at East Maloney Road, West Maloney Road, and Montlake Drive.
A greenway is also part of the project. It will also be constructed along the southbound section, from Montlake Drive to south of Alcoa Way Shopping Center, and will eventually provide a connection between the Knoxville and Blount County Greenways.
September 2017 - The picture above is a panoramic view of the site of Wall #8, including the cuts near Barber HIll and the fills at Mt. Vernon. Vegetation is starting to grow in these areas, as well as above the wall.
Contract crews continue to work on the wall, which is critical to the project. Work is also underway on storm drain installation and utility relocation.
