About the Oak Hill Parkway

Oak Hill Parkway

The Texas Department of Transportation (TxDOT) and the Central Texas Regional Mobility Authority (Mobility Authority) have partnered together to improve long-term mobility at 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 55th most congested roadway in the state of Texas (Texas Transportation Institute, 2016)
  • 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)
