This standard deck girder bridge crosses 2100th Street near the town of Defiance.
Built in 1905, the bridge features a single deck girder span, with a concrete ballasted deck. The structure sits on concrete abutments.
The ballasted deck is a feature commonly used on main line bridges, as it protects the steel superstructure of the bridge and allows for an even and consistent draining of water. While most deck panels like this have failed on nearly every Milwaukee Road bridge, they appear to remain in fair condition on this structure.
Overall, the bridge appears to be in fair condition. Significant cracking of the substructures and deck slabs of the bridge has occurred, but the concrete deck has prevented widespread serious deterioration on the steel.
The author has ranked this bridge as being locally significant, due to the common design.
