In 2004, the U.S. Department of Interior estimated 1.5 million people visit the area’s famous red rocks, which include the trails around Moab, the Colorado River, Arches and Canyonlands national parks, and Dead Horse Point State Park. In 2009, UDOT found 8,585 vehicles a day crossed the Colorado River Bridge to and from Moab.

Construction of Utah’s first concrete segmental bridge began in January 2009. The new concrete segmental bridge is the gateway to Arches National Park and has a strong emphasis on blending with the canyon walls so that the landscape remains the focus of the pristine environment. The bridge will replace the existing bridge with a new, sustainable bridge built in balanced cantilever construction above the river to preserve the environment and maintain recreational uses of the river. The community selected a rock texture on the piers and a mineral stain for the concrete will further blend the new Colorado River Bridge with its canyon backdrop. The twin, 1025’ bridge features an arching main span of 438’ (Utah’s longest concrete span) with only one pier placed in the water, was planned to further reduce impacts to the river.

On February 8, 2010, just thirteen months after construction began traffic along US 191 in Moab, Utah began using the southbound bridge across the Colorado River. A parallel structure is expected to be complete by the end of the year. The last segment for the U.S. 191 Crossing of the Colorado River in Moab, Utah was placed on October 28, 2010. The bridge is expected to open to traffic by the end of 2010.

The bridge was designed by FIGG and is being built by Wadsworth Construction for the Utah Department of Transportation.
