Dolores River Bridge

Montrose County

Crossing the Dolores River in a remote location just east of Bedrock, the 1952 steel rigid connected Pennsylvania through truss structure’s single span runs for 129 feet.  The bridge was designed by the Colorado Department of Highways, fabricated by Midwest Steel & Iron Works, and built by Gardner Construction Company.

Never commonly used in Colorado, Pennsylvania trusses represented a refinement of the standard Pratt truss, both of which were pioneered by the railroads and later constructed to carry vehicular traffic.  In essentially unaltered condition, it is a rare Colorado example of its type.  Listed under Highway Bridges in Colorado Multiple Property Submission.
