For a pin connected Pratt through truss bridge, this structure has a substantial span length. Its long length, which usually results in higher trusses, combine with a narrow deck width to give the bridge a tall feeling. This bridge is composed of nine panels yielding a total structure length of 142 feet. Although the builder plaque obviously was stolen, the Penn Bridge Company is clearly associated with this bridge. The Penn Bridge Company was a company that really took aesthetic design of its bridges right down to the tiniest detail. Their bridges often feature little medallion-like motifs on the portal bracing that feature various figures or designs or say "PENN" on them. This bridge has those decorations, and in addition, those motifs even appear on the railings!
Information and Findings From Ohio's Historic Bridge Inventory
The bridge carries a 1 lane road over a stream in a sparsely developed, rural setting.
The 1 span, 142'-long, pin-connected Pratt thru truss bridge has built-up compression members and eyebar tension members. It has lattice portal bracing with decorative builders plaques atop the portals.
Summary of Significance
The 1893 truss bridge, which is among the early and
technologically significant surviving examples of its type/design in the
state, has been determined eligible as the result of advancing a
rehabilitation project (SHPO letter, 5/21/08).
The bridge is one of over 150 extant pin-connected truss bridges dating from 1874 for pony trusses and 1876 for thru trusses. Twenty six predate 1888 and represent the era of experimentation that evolved into standardized designs by about 1888. This example has moderate significance because the genre and the fabricator are so well represented in Ohio.
