Preserving Red Cliff Arch

This article describes a recent rehabilitation project, the 64-year-old Red Cliff Arch Bridge, which carries U.S. Highway 24 over Eagle River in the Rocky Mountain Region of Colorado, and how it maintains historical integrity while meeting current Federal safety standards. The concrete, reinforcing steel, and paint on the structural steel were decaying and corroding and severely straining maintenance forces' ability to keep up with the repairs. Rehabilitation, which cost $3.6 million, focused on replacing and widening the bridge deck, repainting the steel portions, working on the abutments, girders, and bridge rail---all this while maintaining the historic structure's appearance. The structure was widened to accommodate modern traffic volumes and new materials were used wherever possible to enhance the bridge's service life and durability. Concerns for crew safety were met by using an innovative work scaffold under the bridge deck that provided a safe and efficient area for the workers and inspectors, contain falling objects, and protect the county road. Rebuilding was done with modern equipment. All architectural elements were duplicated from the original drawings. The Colorado Department of Transportation met with media and public officials throughout the rehabilitation project to apprise the town of Red Cliff and travelers about progress and matters affecting businesses and the community, such as accessibility, detours, and closings.
