Located in Briggs Woods State Park near Webster City is this deck truss, crossing the Boone River.
Built in 1901 to replace a previous structure, the bridge features a Double Intersection Warren Deck Truss, a design rather unusual on railroads. The bridge was further altered in 1909, when the deck girder approaches were added.
While Iowa, Minnesota, Wisconsin and Illinois undoubtedly have a higher concentration of this design as compared to surrounding states, the bridge must still be considered unique on a broad level.
The structure features riveted connections, deck plate girder approaches and stone substructures. This stone work likely dates to 1901, as the previous bridge was likely wooden.
The author has ranked this bridge as being moderately significant, due to the unique design.
