The Williams Drive diverging diamond interchange project is steadily making progress, Texas Department of Transportation public information officer Bradley Wheelis said.

Crews expect to begin the demolition and reconstruction of the Williams bridge later this summer.

TxDOT and the Capital Area Metropolitan Planning Organization are funding the $70 million project.

Wheelis said other upcoming work includes widening the northbound I-35 frontage road, reconstructing the southbound I-35 frontage road and constructing a new entrance ramp along southbound I-35.

Most recently, TxDOT crews reconstructed driveways at Austin Avenue and are constructing designated turn lanes at the Williams intersection.

Construction started in October 2020 and is expected to be complete mid-2023.


CR 245 improvements

Williamson County began a series of improvements meant to better traffic flow around Sun City in July. The project consists of reconstructing the two-lane CR 245 from Williams Drive to Ronald Reagan Boulevard to an interim three-lane roadway with a center turn lane. The three-lane roadway will eventually be expanded to a six-lane road.
