BURNET – TxDOT has reduced the speed limit along US 183 from SH 29 in Williamson County through Briggs in Burnet County, after completing a speed study on the busy highway. 

“Safety is our number one priority at TxDOT,” said Terry McCoy, Austin District Engineer. “We heard the concerns of the community and ordered a speed study for the road, which ultimately determined the speed limit could be reduced.”

Speed limits are set through an engineering study—called the 85th percentile method—that reflects the safe and reasonable speed of the majority of drivers on a particular roadway. This is a sound engineering principle that allows TxDOT to set speed limits that maximize safety that are respected and obeyed by motorists. In addition to speed checks, crash history, turning movements, and roadway conditions are also considered during the study.

The community requested the reduction, due to increased traffic and the number of homes and businesses located along the roadway. The speed study indicated the speed limit could be reduced from 70 to 65 mph on US 183 from SH 29 to the east side of Briggs, and then further reduced to 60 mph through Briggs.

“Burnet County welcomes any and all TxDOT projects, programs and initiatives that enhance safety on our roadways,” said Burnet County Judge James Oakley. “We applaud TxDOT’s efforts to address issues that have been identified.“

The reduction in speed was approved by the Texas Transportation Commission. The new speed limit signs were installed last week.

In addition to the speed limit reduction, improvements will be made to the continuous left-turn lane, to keep drivers from using the lane for passing.
