McNary Bergeron & Associates - Engineered Construction®

Project Highlights

State Highway 82 crosses the large Maroon Creek basin on the oldest bridge in service on the Colorado state highway system. Originally constructed as a railroad trestle bridge in 1888, the Maroon Creek Bridge was converted for highway use in 1929. The bridge is currently classified as needing replacement given that its sufficiency rating is now only 9 points out of 100. The replacement bridge was designed to complement the historic look of the existing bridge, which will be left in place as a pedestrian bridge to honor its designation in the National Historic Register.

Our Role
