EFP Bridge over Owl Creek

The EFP Bridge spans Owl Creek in Hot Springs County, Wyoming. The bridge was erected in 1919-20 by the Monarch Engineering Company of Denver and spans 124 feet (38 m) with a total length of 126 feet (38 m). The rigid 7-panel camelback through-truss was nominated for inclusion on the National Register of Historic Places as one of forty bridges throughout Wyoming that collectively illustrate steel truss construction, a technique of bridge design that has become obsolete since the mid-twentieth century. The bridge is supported on sandstone abutments and has a timber deck, 15 feet (4.6 m) in width.

The EFP Bridge was placed on the National Register of Historic Places in 1985.
