A brief history of the Chicago & North Western Iowa Division mainline, now part of the Overland Route:


This standard through girder bridge is the second crossing of Linn Creek.
Built in 1899 and 1901, this bridge features two through girder spans, set onto concrete substructures.
It is believed that the superstructure was fabricated in 1899, while it was erected in 1901.
Overall, the bridge appears to be in fair condition. The substructures appear to be in good condition.

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