HAYS COUNTY, Texas (KXAN) — Over the next seven months, Post Road at the Blanco River will be closed as crews work on constructing a new bridge to replace the temporary that has been in place since 2015.

The original bridge connected Kyle to San Marcos was destroyed during the May 2015 Memorial Weekend flood, when a wall of water came rushing down. The Blanco River crested at 43 feet that day. Pieces of the old bridge can still be seen laying on the banks of the Blanco River.

Starting July 24, drivers should plan on using alternative routes if they need to cross the Blanco River. The new bridge will include two lanes and 4-foot shoulders. For the past two years, the temporary bridge was made by using a railroad flatbed car as the main, one-lane crossing.

“You have to wait for one car to cross before you can cross, so sometimes that creates a line too and the bridge is pretty shaky sometimes, it can be pretty scary,” said Melissa Guardiola, who drives the road daily for her job.

Guardiola says she pulled up to the bridge Monday afternoon surprised to find construction workers demolishing the temporary bridge.

“That’s going to be a big inconvenience, I was hoping it was going to be done in like a week or so, I wasn’t sure what was going on,” said Guardiola.

She delivers mail and says the detour is adding an extra 30 minutes to her work day. “I have to go back towards Aquarena Springs, back towards San Marcos and come around all the way through Yarrington and come back this way. After I’m done here I have to go back to Yarrington and then back across,” she said.

To get around the construction, detour signs are pointing drivers to Interstate 35.

The Fischer Store Road bridge was the other west-to-east bridge that crossed the Blanco River that was destroyed during the floods.
