Located south of Nora Springs, this deck girder bridge crosses an unnamed creek.
Built in 1963 to replace a failed stone arch bridge, this structure was an emergency repair. Because of this, a secondhand deck girder span was reused from an unknown location.
This deck girder span reportedly dates to 1899. It is unknown where it was built originally, as the Rock Island oftentimes reused spans where feasible.
Currently, the bridge consists of this deck girder span, set onto timber substructures. It is approached by trestle spans.
Overall, the bridge appears to be in good condition, after the fire damaged material was replaced in approximately 2011.
Photos show an arch at this location destroyed by a major derailment. It is likely that if that derailment did not happen, the arch would still be here today.

The author has ranked this bridge as being locally significant, due to the common design.
