No active projects are under construction in Precinct 1, but Daigh said there are “lots” of projects under design.

What they’re saying


“Williamson County is unique in that when we do projects, we partner with our cities,” Precinct 2 Commissioner Cynthia Long said. “I just want to highlight that, and just [give] a shout out and a thanks to the cities.”

Precinct 4 Commissioner Russ Boles, whose precinct has the most active road projects, said a lot of areas currently in Williamson County will one day become part of existing cities.

“It makes sense to have a regional effort,” Boles said. “The fact that we have worked regionally with our partners is going to allow that development to be a success.”

Remember this?


Segment 3 of the East WilCo Highway opened to traffic on June 21, Community Impact previously reported. The project expanded the two-lane RM 3349 and CR 101 roadways into a four-lane divided roadway with bridges over Hwy. 79 and the Union Pacific Railroad.

“This bridge and where it intersects at [Hwy.] 79 is going to be the center of east Williamson County in the years to come,” Boles said June 17. “We are working to try and get the same connectivity that Commissioner Long has been able to get with Ronald Reagan on the west side, and this bridge is a key factor.”

The bridge over Hwy. 79 is the most expensive project completed in Williamson County to date, Boles said.

Segment 3 was funded through the Williamson County 2019 Road Bond, and the Texas Department of Transportation contributed $95 million toward construction, according to a county news release.​
