Work is also ongoing with Round Rock's railroad quiet zones project, described below:

Railroad quiet zones

Construction includes city of Round Rock and Union Pacific Corp. railroad work at street and railroad intersections. Crossings are being brought up to compliance with federal standards regarding quiet-zone requirements. Crossings are electronically controlled by the train, which triggers traffic signals and clears the tracks of motorists. Union Pacific has installed signals at Burnet Street and St. Williams Street, though both are currently inactive. Status: Phase 1 awaiting a letter of authorization from Union Pacific for the contractor to begin work; Phase 2—Burnet to Red Bud Lane—is progressing, and crews are working on the Hwy. 79 railroad crossing

Cost: $4.4 million
