The project will widen from two to three mainlanes for through traffic in each direction, as well as add three frontage-road lanes in each direction. An overpass for the US 290 mainlanes over William Cannon Drive will be built, along with direct-connect flyovers between US 290 and SH 71.
Along SH 71, the flyover ramps will extend past Scenic Brook Drive where the mainlanes will transition to a five-lane rural highway with U-turns for local access.
Bicycle and pedestrian accommodations will be built along the entire corridor, including a seven-mile shared-use path, sidewalks, new landscaping, tree plantings and corridor aesthetics.
Additional project components include cross-street intersection improvements, U-turn lanes, an offsite ~67 acre-feet storm water detention pond complete with a dam and spillway as well as multiple water quality treatment ponds along the corridor.
