Utah's Longest Concrete Span and First Segmental Bridge Opens to Traffic - US 191 Bridge Over the Colorado River, Moab, Utah

SEGMENTS, WINTER 2012, VOL. 57

The US 191 crossing of the Colorado River in Moab, Utah opened to traffic on November 29, 2010. The new bridge is Utah’s first concrete segmental bridge and has the state’s longest concrete span at 438'. The bridge was designed by FIGG and built by Wadsworth Brothers Construction for the Utah Department of Transportation (Fig. 22).

The new sustainable bridge was built in balanced cantilever to preserve the environment and maintain recreational use of the river. Located just outside of Arches National Park, the variable depth structure creates an arching appearance similar to many of the natural rock formations nearby. The bridge is stained using colors of the soil to blend seamlessly with its canyon surroundings.
