Located near the ghost town of Creston is this massive bridge crossing the Cheyenne River.
Built in 1907, the bridge here was the original to this line.
Consisting of a trio of 6-panel Pratt Through Trusses, the bridge is also approached by deck girder spans and trestle spans.
Unique to this bridge are the connections on the truss spans. These connections are a hybrid pin connected and riveted design, rarely seen on large trusses like this.
The substructures of the bridge are mixed, with concrete piers supporting the main trusses and deck girders, with trestle spans resting on wooden substructures.
Within the last decade, the center pier of the bridge became severely undermined, nearly causing the collapse of this bridge.
However, the State of South Dakota decided to rebuild the bridge pier, with a new steel piling pier.
Overall, this bridge remains in good condition. It has been chained off to prevent people from getting hurt. The bridge has a clouded future, as it was purchased by the Ringneck & Western Railroad. Despite being back in railroad ownership, the bridge is still closed to traffic, and all rails removed.

The author has ranked this bridge as being regionally significant, due to the uncommon design and odd truss style.
The photo above is an overview. The photo below is a picture inside the truss.
