CDOT ProjectGrandAve2line

The Grand Avenue Bridge (GAB) project is the largest infrastructure project on the Western Slope in 25 years. Now in phase three of this five-phase project, crews are working to replace the more than five-decade-old traffic bridge in Glenwood Springs.

Use this site to learn more about our work to improve one of two routes for motorists to cross the Colorado River and Interstate 70, and its construction of a new pedestrian bridge along the GAB. You can also follow us on Facebook.
