Here are five Round Rock transportation projects to know this month.

Railroad quiet zones

Construction includes the city of Round Rock and Union Pacific Corp. railroad work to bring street and railroad crossings up to compliance with federal quiet-zone standards. Crossings are electronically controlled by the train, which triggers traffic signals and clears the tracks of motorists. Union Pacific has installed signals at A) Burnet Street and B) St. Williams Street.

Status: Phase 1, Burnet Street to St. Williams Street, is anticipated to be complete in summer 2020; Phase 2, from Burnet to Red Bud Lane, is progressing, with crews currently working at the Hwy. 79 railroad crossing.

Cost: $4.4 million


Funding sources: city of Round Rock, Texas Department of Transportation

The project is designed to improve safety and mobility on I-35’s northbound frontage road. Work on the expanded frontage road will widen it from two to three lanes, relocate the exit ramp and add an extended exit lane between RM 1431 and FM 3406.

Status: Widening and reconfiguration of the left side of the frontage road continues; widening of Chandler Creek bridge is underway.
