The US-191 Realignment Project will ultimately replace the 2.6 mile switchback portion of the highway located 12 miles north of Vernal. The proposed improvements will enhance safety by adding a continuous uphill climbing lane and a southbound passing lane, eliminating the switchbacks and providing standard horizontal curves, optimizing grades to help trucks negotiate curves, installing a runaway truck ramp, and providing standard width shoulders.
