Located near the town of Woolstock, this large bridge crosses Eagle Creek along County Road C70.
Originally built in 1902, the bridge originally featured a large Quadrangular Through Truss with laced endposts and a distinct M-frame portal. However, it was expanded in 1914, when deck girders were added to either side to replace trestles. The substructures of the bridge consist of concrete and stone.
Trusses like this were common in the Iowa Division, and were oftentimes built around 1902, during a time of rebuilding. The Quadrangular design was a favorite of the entire C&NW system, and many variations still exist today.
Currently, the bridge is operated by Union Pacific. It is highly visible from the nearby county road.
Overall, the bridge appears to be in good condition. Little notable deterioration was found on the structure.
The author has ranked this bridge as being moderately significant, due to the truss design.
