A brief history of the Chicago & North Western Sacton-Sargent Bluff branch:


Located along Iowa Highway 140 between Moville and Kingsley, this small concrete encased beam bridge crosses a cattle pass.
Built in 1907, the bridge features a single concrete encased beam span, set onto concrete substructures.
This style design was commonly used by the C&NW and other railroads, as it was cheap and efficient to build. While a standard box culvert may suffice, this design provided extra strength for spans that were typically too long to be box culverts.
Overall, this bridge appears to be in fair to poor condition, with significant deterioration noted throughout the structure.

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