Crossing the Rock River below a large deck truss bridge, this structure is set on a sweeping curve.
Built in 1900, the bridge was built with seven deck girder spans. These spans were set onto skewed stone piers, and concrete abutments.
At some point in approximately 1980, the southern two spans were replaced with newer deck girder spans.
Overall, the bridge appears to remain in good condition.
