PDF of TDOT’s proposed redesign of the intersection of Highway 46 with Livestock Road and Alexander Drive.
The fourth new traffic signal proposed to be added in the Tennessee Department of Transportation’s Traffic System Management plan for Highway 46 would be at a redesigned intersection with Livestock Road and Alexander Drive. The $8.3 million plan proposes to shift Livestock Road, which accesses the Dickson County Livestock Center and the truck parking lot for Pilot, slightly to the north of its current location so it aligns directly with Alexander Drive, the street between Alexander Chevrolet and Victory Nissan. This intersection was previously determined to be in need of a traffic signal because of the railroad crossing on Livestock Road. The projected cost of relocating Livestock Road is $674,000, which is included as a state-funded improvement and not part of the non-participating partnerships that are to be funded by the city of Dickson. The redesigned intersection would include a left-turn lane and combined through-traffic and right-turn lane for the Livestock Road approach with a preemption to shut down traffic when a train is crossing. Alexander Drive would have only one approaching lane and no changes would be made to Highway 46, which would have two through lanes and left-turn lanes in each direction. The signal at the intersection would be connected and coordinated with the signals at Christi Drive and the two Interstate 40 entrance and exit ramps. TDOT has already begun survey work to prepare for the design phase of the project.
