TxDOT is working on a new project to make improvements to US 79 between I-35 and east of FM 1460 (A.W. Grimes), with the goals of improving traffic flow and increasing safety for travelers in Round Rock. The proposed project includes installing a raised median for safety and widening the existing US 79 roadway by adding a third travel lane in each direction. Additional improvements could potentially include building new overpasses at US 79/Mays Street and US 79/FM 1460, and altering the existing US 79/I-35 intersection.
TxDOT recently concluded the public comment phase on the Draft Environmental Assessment and the recommended build alternative. After taking those public comments into consideration, the next steps (according to the TxDOT project fact sheet) will likely be right of way acquisitions before utility relocation and finally, road construction.
