History

The first Manzanola Bridge was built in 1908, near Clifton in Mesa County over the Colorado River. It was replaced by a new design in 1950 and moved to a new location over the Arkansas River connecting Manzanola, Colorado with Crowley County, Colorado. At the new location, the new bridge replaced a "three-span pinned truss" which was built in 1908.[3][4]

On June 24, 1985, the bridge was added in to National Register of Historic Places.[5] And, in 1994, the bridge was demolished and a much more modern structure was cosntructed to handle the traffic of Colorado State Highway 207.

The 1950s structure was used to be considered as one of the earliest "rigid-connected vehicular trusses" in Colorado and one of seven "riveted Pennsylvania through trusses". At the time of its existence, it was recorded as the "longest span roadway truss" in the state.[6]

Finally, on July 7, 1994, the bridge's name was removed from the National Register of Historic Places.[7]
