The Oak Hill Parkway project will reconstruct and widen roughly seven miles of US 290 from the east end of Circle Drive to Loop 1 (MoPac Expressway) and SH 71 from US 290 to Silvermine Drive in Travis County, west of downtown Austin. This portion of interstate highway will be transformed to improve long-term mobility, safety and reduce traffic for 29th most congested roadways in the state of Texas*.
In a joint venture, Balfour Beatty will design and construct an upgraded interstate highway that will consist of constructing two to three mainlanes as well as adding two to three frontage-road lanes in each direction. An overpass for the US 290 main lanes over William Cannon Drive will be built, along with direct-connect flyovers between US 290 and SH 71.
Additional project components include bicycle and pedestrian accommodations along the entire corridor, cross-street intersection improvements, U-turn lanes, upstream water detention, storm water detention and water quality treatment ponds.
Construction commences in early 2021 with an expected completion scheduled for 2026.
