ELK MOUNTAIN — A historic bridge is being torn down this fall following the Wyoming Department of Transportation's determination that the structure was too dilapidated to be restored.

The Warren Truss bridge is one of three that historian Clayton Fraser says were built in the state, its uncommon structure earning it a spot on the National Register of Historic Places.

The bridge was built in 1923 over the Medicine Bow River in Elk Mountain, located in southern Wyoming.

Yoder-based Dietzler Construction was awarded the transportation department's $1.6 million contract for the project. The deadline for completion is in June 2016.
