US 79

in progress

The Texas Department of Transportation (TxDOT) Austin District is proposing improvements to United States Highway 79 (US 79) between Interstate 35 (I-35) to east of Farm-to-Market Rd 1460 (FM 1460) within the city of Round Rock in Williamson County, Texas.  Existing Facility Within the project limits, US 79 consists of four 12-foot main lanes (two in each direction) with 10-foot outside shoulders. Some locations along the corridor have a central turn lane measuring 14 feet. The existing US 79 right-of-way (ROW) varies from 150 to 300 feet wide.  Proposed Facility Proposed improvements include widening the existing US 79 roadway to add a third travel lane in each direction and installing a raised median for safety. Improvements to intersections would include potential overpasses at US 79/Mays Street and US 79/FM 1460, and altering the US 79/I-35 Intersection. Driveways and access points would be modified to improve safety and traffic flow. The proposed improvements also include installing shared-use paths on both sides of US 79 to improve pedestrian and bicycle accommodations. The proposed project would require approximately 7.07 acres of new right-of-way. Figures used in this PCR were made from a combination of provided information on alternative design options.
