About the Oak Hill Parkway


The intersection of US 290 and SH 71 serves as a gateway to southwest Travis County and is a key route between central Austin and fast-growing suburban and rural communities such as Lakeway, Bee Cave, Dripping Springs, and Johnson City. However, congestion at this intersection has reduced mobility, reliability, and quality of life for the Oak Hill community and corridor travelers. The Oak Hill Parkway Project will increase safety and mobility in the area.

In 2012, we launched an environmental study so that we could collaboratively propose a solution that effectively addresses congestion, respects the environment, and adds value to the Oak Hill community. Through extensive community outreach and engineering analysis, a recommended build alternative was determined, received public comment and final approval from the TxDOT Environmental Affairs Division in 2018.

The Oak Hill Parkway Project is anticipated to break ground in late 2020, bringing an end to a decades-long journey to bring congestion relief to southwest Travis County. Construction is expected to begin in late 2020 and last for 5 years. We welcome you to sign up for updates here.


  • TxDOT will build an upgraded, state-of-the-art roadway consisting of three mainlanes for through traffic in each direction, as well as 2-to-3 frontage-road lanes in each direction.
  • An overpass for the US 290 mainlanes over William Cannon Drive will be built, along with flyovers between US 290 and SH 71. At this location, the US 290 mainlanes will be depressed, or go under, SH 71.
  • From Old Bee Caves Road to William Cannon Drive, the westbound US 290 mainlanes and frontage roads will be north of Williamson Creek, with the eastbound US 290 mainlanes and frontage roads south of Williamson Creek.
  • Intersections will be constructed along US 290 at Convict Hill Road, RM 1826, Scenic Brook Drive, and Circle Drive (South View Road) where the highway will go below ground and the cross street will be at ground level.
  • U-turn lanes will be constructed at intersections along US 290 and SH 71 to allow vehicles traveling on frontage roads to U-turn to access the opposite direction frontage road.
  • Along SH 71, the flyover ramps will extend past Scenic Brook Drive where the mainlanes will transition to a five-lane (three lanes northbound, two lanes southbound) rural highway with U-turns for local access.
  • Significant bicycle and pedestrian accommodations will be built along the entire corridor, including 14 miles of shared-use path and 1 1/2 miles of sidewalks.
  • An offsite stormwater detention pond will be built upstream of Williamson Creek on Old Bee Caves Road to reduce potential flooding, and multiple water quality treatment ponds would be built within the corridor.
  • Additionally, new landscaping, tree plantings, and corridor aesthetics will be part of the construction plan.
