History
editThe 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 to the National Register of Historic Places.[5] In 1994, it was demolished and a more modern structure was constructed to handle the traffic of Colorado State Highway 207.
The 1950s structure was considered one of the earliest rigid-connected vehicular trusses in Colorado and one of seven riveted Pennsylvania through-truss bridges. At the time of its existence, it was recorded as the longest span roadway truss in the state.[3]
On July 7, 1994, the bridge's name was removed from the National Register of Historic Places.[6]
