Staff Reports

AUSTIN – The Texas Department of Transportation was joined by officials from the City of San Marcos, Hays County and the Capital Metropolitan Planning Organization to break ground on the I-35 at SH 123 project.

“San Marcos is one of the fastest-growing areas in our region, with more than 155,000 vehicles traveling this segment of I-35 daily,” said TxDOT Austin District Engineer Tucker Ferguson. “The I-35 at SH 123 project is another example of how TxDOT is focused on enhancing mobility in a smart way forward for our growing communities and what better place to do that than in San Marcos.”

The I-35 at SH 123 project will reconstruct and improve the SH 123 intersection and reverse entrance and exit ramps between SH 80 and RM 12. It will also reconstruct the northbound and southbound I-35 frontage roads, including the northbound bridges over Willow Springs Creek and the San Marcos River.

“The project will allow us to address flooding issues by raising part of the frontage road,” commented San Marcos Mayor Jane Hughson. “We appreciate the safety changes made by TxDOT to reconfigure entrance and exit ramps.”

The project will also add extended entrance/exit lanes and enhance bicycle and pedestrian paths throughout the corridor.

“I want to thank TxDOT and our continued partnership to ensure we are moving forward the many needed projects to provide the best possible solutions to address safety, mobility and connectivity in Hays County and our region,” said Hays County Commissioner Debbie Gonzales Ingalsbe.

The $107 million project is expected to be complete by early 2025, weather permitting. The contractor is Webber, LLC.
