The City of Round Rock, in coordination with the Texas Department of Transportation (TxDOT), is updating a previous environmental study and design schematic for approximately 2.5 miles of US 79 from I-35 to just east of A.W. Grimes Boulevard/Farm-to-Market (FM) 1460. The proposed improvements are intended to enhance safety, mobility, access, and pedestrian and bicycle connectivity along the corridor.

This project will widen the roadway to a six-lane divided facility with a raised median and selected median breaks. The project also includes intersection improvements featuring a grade separation at A.W. Grimes Boulevard, signals, turn lanes, modified driveways, sidewalks, and shared-use path upgrades. The updated environmental study and design schematic are anticipated to be completed in 2026. Construction is currently estimated at $82 million, with the schedule dependent on funding availability.

Additional project information is posted on TxDOT’s website, including details for a virtual public meeting and comment period, open through September 16, 2026.
