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 124feet with a total length of 126feet. The rigid 7-panel Parker (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, 15feet in width.[1]
The EFP Bridge was added to the National Register of Historic Places in 1985.
