The bridge is a traditional example of a riveted polygonal warren pony truss. Field bolts on the otherwise riveted connections show the points where the prefabricated trusses were assembled in the field. The bridge retains good historic integrity although original railings were replaced with Armco guardrail. While the guardrail is an aesthetic detriment, the curved shape of the polygonal top chord continues to make this bridge an attractive structure.
At the time of documentation, the bridge displayed dirt buildup on the bottom chord. Owners of bridges need to wash bridges occasionally as part of a proper routine maintenance program to ensure that dirt does not build up in this manner, trapping moisture and leading to avoidable structure deterioration.
This bridge was stated as a later example of a standardized design in Ohio. While a number of earlier rivet-connected Warren pony truss bridges may exist (or did exist) in Ohio, this is an extremely early example of a polygonal Warren truss. Most polygonal Warren pony truss bridges date to 1920 and later. The Historic Bridge Inventory overlooked this fact.
Information and Findings From Ohio's Historic Bridge Inventory
The bridge carries a 1 lane road over a stream in a rural area of active farms.
The 1 span, 84'-long, rivet-connected Warren pony truss bridge has polygonal upper chord ,verticals, and built-up members. The upper chord is composed of toe-out channels with cover plate and lacing. The verticals, diagonals, and lower chords are angles with battens. The built-up floorbeams are connected above the lower-chord panel points. The bridge is supported on concrete abutments.
The bridge has some bolted repairs at the polygonal upper chord gusset plates
Summary of Significance
Although complete except for some bolted repairs, the Warren with verticals pony truss bridge placed in 1910 by the county is not historically or technologically significant. It is a later example of a
standardized design that was used throughout the state. The fabricator is not documented. Extant riveted pony truss bridges in Ohio date to 1897 (25XXXX1), and it is the early examples that represent the transfer of technology from
pinned to riveted field connections.
