Highway Bridges in Colorado
The bridges listed below represent the best examples of their types remaining in place on state, county, and municipal roads in Colorado. Many of the bridges were originally recognized in conjunction with the 1985 Vehicular Bridges in Colorado Thematic Resource nomination prepared after the completion of a statewide bridge survey in 1984.
An intensive statewide survey conducted in the late 1990s resulted in the preparation of a more completed historic context, The Historical and Technological Evolution of Colorado’s Bridges 1880-1958, which addresses in detail the wide variety of designs, construction technologies and operational histories of Colorado’s highway bridges.
