Name of the Project
Oak Hill Parkway infrastructure project.
Location
Austin, Texas, in the US.
Project Owner/s
Texas Department of Transportation (TxDOT).
Project Description
This project is part of the TxDOT’s long-term plan to promote congestion management in one of Texas’ most congested corridors.
The estimated 11 km design-build project will widen and improve US 290 and State Highway 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.
The project will result in the widening of two main lanes to three for through-traffic in each direction, and in 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 State Highway 71.
Along Highway 71, the flyover ramps will extend past Scenic Brook drive, where the main lanes will transition to a five-lane (three lanes westbound; two lanes eastbound) rural highway with U-turns for local access.
Bicycle and pedestrian accommodations will be built along the entire corridor, including an 11 km shared-use path, sidewalks and a trailhead at Williamson Creek on William Cannon drive to accompany new landscaping, tree plantings and corridor aesthetics.
Additional project components include cross-street intersection improvements, U-turn lanes, an upstream water detention to reduce potential flooding, and stormwater detention and water-quality treatment ponds.
