View Historic Bridge Inventory Sheet For This Bridge

This is a well-preserved and relatively long span example of a pin-connected Pratt truss highway bridge.

The Historic Bridge Inventory listed an 1883 construction date for this bridge. The bridge has a modern plaque on it which was added in recent times and is not an original. The plaque has an 1883 date on it. The plaque is clearly designed to resemble this bridge's original plaque. However, the plaque design was only used by the Wrought Iron Bridge Company in the 1890s. This bridge's a-frame portal bracing is a design detail that the Wrought Iron Bridge Company did not start using until ca. 1889-1890. It is the strong opinion of HistoricBridges.org that this bridge was not built in 1883. It does not look like any Wrought Iron Bridge Company bridge built in the early 1880s, yet it follows the design of many 1890s Wrought Iron Bridge Company bridges in precise detail. It is not known how 1883 got associated with this bridge. Perhaps old/unclear historical photos of this bridge had a photo of the plaque and a "9" was mistaken for an "8." Also of interest, despite the 1883 plaque on the bridge, the National Bridge Inventory lists an 1890 construction date for the bridge. Either 1893 and 1890 would make a lot more sense for this bridge.

None of this changes the fact that this is an outstanding example of a Wrought Iron Bridge Company Pratt truss bridge, and thus whatever the construction date of the bridge, this is a beautiful historic bridge.
