The Oak Hill Parkway project, a proposed expansion of US Highway 290 and State Highway 71, recently received environmental clearance following the completion of a six year study evaluating the potential impact of construction along the two highways. The Final Environment Impact Statement, released on December 21st, concluded that Alternative A – a non-tolled 12-lane project – has “fewer social, economic and environmental impacts,” than other proposed construction alternatives for the highways.
More specifically, the Oak Hill Parkway project consists of three main lanes for through traffic and three frontage-road lanes in each direction on both highways. An overpass for the US 290 main lanes over William Cannon Drive would also be built, in addition to flyovers between US 290 and SH 71. Bicycle and pedestrian accommodations would also be incorporated throughout the corridor. The estimated construction cost of the Oak Hill Parkway project is $440 million, and the earliest the project could break ground is 2020. The project is expected to take four years to complete.
