The details
Northbound Convict Hill vehicles will detour to the eastbound Hwy. 290 frontage road. Drivers must utilize the U-turn at William Cannon Drive for access to westbound Hwy. 290. Those traveling westbound on Hwy. 290 must use the RM 1826 U-turn to access Convict Hill Road.

The Texas Department of Transportation is currently reconstructing Hwy. 290 in Oak Hill headed towards Dripping Springs, transforming the existing four-lane, undivided roadway to a six-lane divided highway with both new frontage roads and miles of shared-use paths.
New intersections are being constructed at Convict Hill Road, RM 1826, Scenic Brook Drive and Circle Drive where the highway will be sunken below the existing ground level and the cross street will remain at ground level.
In addition, an overpass for the Hwy. 290 mainlanes over William Cannon Drive will be built, along with new flyovers between Hwy. 290 and SH 71. At this location, the Hwy. 290 mainlanes will be lowered under SH 71.
The project is now more than halfway complete, according to an update earlier this year. Find additional information about the project here.
