The Texas Department of Transportation is expanding RM 1431 from four to six lanes between Market Street and Cottonwood Creek Trail, according to a representative with the state agency. The project is meant to match the six-lane East Whitestone Boulevard pass-through project that runs from Market to Sam Bass Road, which was completed by the city of Cedar Park, Williamson County and the state transportation agency in 2016.

According to the city of Cedar Park, the temporary speed limit on this section of roadway is 45 mph. City Council approved the construction speed limit in March.
