Residents of the Dripping Springs area who drive toward Austin for work or other activities should be aware of a new traffic pattern at the intersection of US 290 and SH 71, known as the “Y”, in Oak Hill.
Starting Oct. 9, the Texas Department of Transportation (TxDOT) will open a new Single-Point Urban Interchange (SPUI) as part of safety and mobility improvements for the Oak Hill Parkway project. The SPUI operates with a single, three-phase traffic signal to facilitate local movements between US 290 and SH 71.
To see an animation of how the SPUI will work, go to the TXDOT YouTube channel and look for their Sept. 30 video, or go to www.youtube. com/watch?v=mv _z8-YpsKg Additionally, the William Cannon Drive bypass bridge will close as crews complete connections to the US 290 mainlanes and flyovers between US 290 and SH 71. Eastbound US 290 drivers will detour to the eastbound US 290 frontage road. The William Cannon bypass bridge will reopen for westbound traffic upon completion of the project in 2026.
Road signs will be in place to alert drivers of new traffic patterns. TxDOT urges drivers to use caution when driving through the work zone.
