This pony truss is noteworthy for its unusual end post / top chord connection cover plates which double as builder plaques and list the Canton Bridge Company as builder. The bridge is an otherwise traditional structure and included built-up floorbeams. Original railings do not remain on the bridge.
This bridge has been altered at the end posts with additional welded materials added. Improperly mounted Armco guardrails detract from the visual quality of the bridge and do nothing to protect the fracture critical truss members of this historic bridge. Historic bridges like this one deserve to be better protected from the damage an automobile-bridge collision can cause, assuming there is in fact enough of a reason to put Armco guardrails on a quiet rural bridge like this one.
Information and Findings From Ohio's Historic Bridge Inventory
The bridge carries a 2 lane road over a stream in a sparsely developed, rural setting.
The 1 span, 53'-long, pin-connected Pratt pony truss bridge is traditionally composed of built-up compression members and eyebar or rod tension members.
Summary of Significance
The pin-connected Pratt pony truss was fabricated by the Canton Bridge Co. in 1910. It is a later example of a type/design that was developed prior to 1890 and is well represented by earlier and more distinguished examples throughout the state. The not eligible recommendation of the prior inventory remains appropriate.
