The TxDOT Austin District is overseeing the design and construction of Oak Hill Parkway. Atkins serves as TxDOT’s general engineering consultant, and Atlas will provide owner verification testing and inspection.
The Austin District plans, designs, builds, operates, and maintains the state transportation system in the following counties: Bastrop, Blanco, Burnet, Caldwell, Gillespie, Hays, Lee, Llano, Mason, Travis, and Williamson.
The Texas Department of Transportation is responsible for maintaining 80,000 miles of road and supporting aviation, maritime, rail, and public transportation across the state.
Through collaboration and leadership, TxDOT delivers a safe, reliable, and integrated transportation system that enables the movement of people and goods. Visit TxDOT.gov.

WHAT WILL BE BUILT & WHAT DOES THE PROJECT ENTAIL
Oak Hill Parkway Project Location Map | Courtesy of TxDOT
TxDOT is building an upgraded, state-of-the-art roadway consisting of 2-to-3 non-stop US 290 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 new flyovers between US 290 and SH 71. At this location, the US 290 mainlanes will be lowered under SH 71.
New 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 the existing ground level and the cross street will remain at ground level.
U-turns will be constructed at intersections along US 290 and SH 71 to allow vehicles traveling on frontage roads 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 5-lane (three lanes northbound, two lanes southbound) highway with U-turns for local access.
Oak Hill Parkway Bicycle and Pedestrian Routes | Courtesy of TxDOTSignificant 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 near Old Bee Caves Road and Sunset Ridge to reduce potential flooding, and multiple water quality treatment ponds will be built within the corridor.
New landscaping, tree plantings, and corridor aesthetics will be part of the construction plan.
CONSTRUCTION IMPACTS TO LAST ROUGHLY FIVE YEARS
July 1, 2021: Groundbreaking ceremony
Late 2021: Begin major activity on US 290 beginning at the far west and far east segments of the project
Mid-2022: Begin major activity on SH 71
Late 2022: Begin major activity at the US 290/SH 71 “Y” interchange segment
2026: Open to traffic
Activity will occur throughout the entire corridor simultaneously. The construction sequence that TxDOT will use for the Oak Hill Parkway project will be an “outside-in” approach. This prioritizes the construction of the new frontage roads (on the outside) prior to the reconstruction of the mainlanes.
The exact timing of traffic shifts and lane closures will be developed as the design of the project progresses. When information becomes available, TxDOT will distribute this information to businesses, residents, and drivers through multiple communication channels (e.g., e-blasts, tweets, website updates, and media alerts).
Construction schedules are fluid and intended to adapt to time, circumstances, and weather delays. The goal of the construction plan will be to keep as many lanes open as possible while the project is being built.
