TxDOT Oak Hill Parkway

Fluor’s joint venture with Balfour Beatty was selected by the Texas Department of Transportation (TxDOT) to reconstruct and widen US 290 from approximately the east end of Circle Drive to Loop 1 and SH 71 from US 290 to Silvermine Drive in Travis County, west of downtown Austin, Texas.

The approximately seven-mile design-build project will widen and improve US 290 and SH 71 through Oak Hill and act as a gateway to the hill country. It will also serve as a key route to Austin for the residents of Oak Hill, Lakeway, Bee Cave, Dripping Springs and other growing communities west of Austin.



Client's Challenge

The Oak Hill Parkway project is part of TxDOT’s long-term plan to promote congestion management in one of the state’s most congested corridors. When completed, the project will help improve mobility and operational efficiency as well as improve safety and emergency response.



Fluor's Solution

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.



Conclusion

Construction is scheduled to begin in 2021 with project completion slated for 2025.
