Red Cliff Arch Rehabilitation Project

摘要

Located near Red Cliff, CO, southwest of Vail on U.S. Highway 24, the Red Cliff Arch Bridge was originally completed in 1941. Sixty-three years later, the bridge was in dire need of help. Due to age, as well as loads and traffic that were not envisioned in the 1940s, the bridge needed an extensive rehabilitation. The newly rehabilitated Red Cliff Arch Bridge was dedicated in November 2004. Preserving the structure's historical integrity, while updating it to current safety standards and strength requirements, was the driving force behind the project. Safety was also a critical concern during construction. With the bridge 200' above a valley floor, traditional scaffolding was not feasible. The bridge crosses over an existing county road, a river, and a railroad. Any falling material would have been hazardous not only to the public, but also to the environment. A hard platform scaffolding system was required and provided several safety and schedule benefits.
