About
The US-191 Realignment Project replaced the 2.6 mile switchback portion of the highway located 12 miles north of Vernal with an alignment with fewer turns and standard horizontal curves. The improvements 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.
Project Area
Project Improvements
A continuous uphill climbing lane and a downhill passing lane was added to allow traffic to pass slower traffic safely |
An emergency truck ramp was added |
Grade reductions in key locations. |
Eliminating the current switchback design reduced the chances of semi-truck rollovers. |
Wider curves along this stretch of highway are easier to navigate and allow motorists to maintain consistent speeds. |
