PROJECT SUMMARY
OAK HILL PKWY
COUNTY:
Travis, TX
ACQUIRING AUTHORITY:
TXDOT
PARAMETERS:
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.
SCHEDULE:
They received environmental clearance in December 2018, so it looks like everything’s a go. They’re hoping for a February 2020 let date, which means they’ll be aggressively acquiring the right of way over the next year
The Austin, Texas city council has approved plans to proceed with construction of an interchange where US 290 and Texas Highway 71 meet at the "Y" in Oak Hill, one of the most congested roadways in Texas. For more information click here.
