The Tennessee Department of Transportation (TDOT) plays a vital role in maintaining and improving the state’s transportation infrastructure, ensuring safe and efficient travel for Tennesseans. In Blount County, TDOT is currently involved in several important projects aimed at road enhancements, safety improvements, and increasing transportation capacity. These projects are essential for accommodating growth and ensuring our roadways meet the needs of the community.
- Alcoa Highway (State Route 115, US 129) Improvements
Alcoa Highway is a key route connecting Knoxville to Alcoa and Maryville, providing access to McGhee Tyson Airport and the Great Smoky Mountains National Park. To address growing traffic volumes and safety concerns, TDOT is undertaking major improvements on this 13-mile stretch of highway. The project involves widening the highway and converting it into a controlled-access facility with grade-separated interchanges. This transformation will improve traffic flow, reduce congestion, and make travel safer for both local commuters and travelers passing through the area. Learn More: Tennessee Government
- Pellissippi Parkway (State Route 162 Extension)
The extension of Pellissippi Parkway is a critical project designed to improve connectivity between Blount County and the surrounding areas. TDOT is extending State Route 162 from its current terminus at State Route 33 to State Route 73, which will include the completion of the SR 33 interchange. The new controlled-access, four-lane highway will feature a concrete median barrier wall and grade-separated interchanges to enhance safety and alleviate traffic congestion.

- State Route 334 (Proffitt Springs Road Improvements)
The proposed improvements to State Route 334, running from near Proffitt Springs Road to just past SR 333 (Topside Road), aim to accommodate increasing traffic, particularly due to the Smith & Wesson Headquarters. The project widens the existing two 11-foot lanes to two 12-foot lanes, with six-foot paved shoulders and curb and gutter along each side of the road. This upgrade will help meet the growing needs of passenger and truck traffic generated by the new facility. Currently in the preliminary engineering phase, the project is expected to begin construction in 2027 and will take approximately two to two-and-a-half years to complete. The project is fully state-funded and will contribute to Blount County’s continued growth. Learn More: Tennessee Government
