Round Rock drivers will need to be on high alert this weekend due to construction work on Interstate 35.
The Texas Department of Transportation will temporarily close IH-35 at Old Settlers Boulevard starting at 8 p.m. Friday night, and frontage roads will be reduced to one lane.
All roadways will reopen Saturday morning at 8 and then close again Saturday night.
TXDOT is closing the roads while crews lift and place large beams for the new bridge over IH-35.
There will be detour signs up to help get you around the closure.
