Construction is now underway on more than 15 miles of State Highway 21 in Hays County from SH 80 to the Caldwell County line. The roadway is being converted to a “super 2” highway with paved shoulders to improve safety between San Marcos and Niederwald.
A super 2 highway helps increase safety by providing a periodic passing lane on a 2-lane rural road. The passing lane alternates from one direction of travel to the other, allowing passing opportunities in both directions for motorists.
“The improvements will allow vehicles to safely pass on what is currently a narrow 2-lane road,” TxDOT Area Engineer Epi Gonzalez said. “Ultimately, this project will help motorists arrive safely at their destinations.”
