About the Oak Hill Parkway

Oak Hill Parkway

The Texas Department of Transportation is working to improve long-term mobility at the intersection of US 290 and SH 71. In 2012, we launched our 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. We anticipate an environmental decision in 2018.


  • US 290 in Oak Hill is the 64th most congested roadway in the state of Texas (Texas Transportation Institute, 2017)
  • Travis County’s population has grown from 212,000 in 1960 to just over 1 million in 2010, increasing congestion (US Census Data, 2013)
  • 868 crashes occurred on US 290/SH 71 between 2010 and 2014, resulting in five fatalities, 20 incapacitating injuries, plus other injuries and property damage (TxDOT, 2015)
  • Drivers wasted more than 454,000 hours per year stuck in traffic on US 290/SH 71 in 2014 (Texas Transportation Institute, 2015)
  • Traffic demand at the US 290/SH 71 intersection will more than double by 2040 (RTG using CAMPO’s travel demand model)


  • TxDOT proposes an upgraded, state-of-the-art roadway consisting of three mainlanes for through traffic in each direction, as well as two-to-three frontage-road lanes in each direction.
  • An overpass for the US 290 mainlanes over William Cannon Drive would be built, along with flyovers between US 290 and SH 71. At this location, the US 290 mainlanes would be depressed, or go under, SH 71.
  • The westbound US 290 mainlanes and frontage roads would be north of Williamson Creek.
  • Intersections would be constructed along US 290 at Convict Hill Road, RM 1826, Scenic Brook Drive, and Circle Drive (South View Road) where the highway would go below ground and the cross street would be at ground level.
  • U-turn lanes would 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 would extend past Scenic Brook Drive where the mainlanes would transition to a five-lane (three lanes northbound, two lanes southbound) rural highway with U-turns for local access.
  • Significant bicycle and pedestrian accommodations would be built along the entire corridor, including a seven-mile shared-use path, sidewalks, and a trailhead at Williamson Creek on William Cannon Drive.
  • Upstream water detention ponds would be built to reduce potential flooding, and multiple stormwater detention and water quality treatment ponds would be built within the corridor.
  • Additionally,  new landscaping, tree plantings, and corridor aesthetics are proposed.
