This bridge appears to be a heavily altered example of an extremely rare bridge type. In this bridge's original design, the lattice railings double as a superstructure and support load. Some bridges of this type just use the lattice railing alone, others were built with an additional dedicated diagonal member that ran down to a floorbeam at the center of the bridge. The latter appears to be the case with this bridge since diagonals are visible on the bridge. This bridge however has largely been bypassed by a modern rolled beam placed at deck level which had been doing the load supporting. An earier retrofit also had added a strip of metal to the top of the girder. Now the bridge is completely closed in a deteriorated state. The bridge also has the unusual and attractive detail of decorative flower motifs on the lattice railings.
Information and Findings From Ohio's Historic Bridge Inventory
The bridge carries a 1 lane of a closed road over a stream in a redeveloping rural area where large houses are being constructed on former farm land.
The 1-span, inverted kingpost pony truss bridge with lattice railings set inside the truss lines is supported on deteriorating ashlar abutments. It has been strengthened by placing rolled beams outside the truss lines to pick up the floorbeam. The upper chords are badly deteriorated and are sagging despite the placement of additional material. Members are severely deteriorated.
Summary of Significance
The short-span, inverted king post, pony truss bridge is a rare example of a distinctive type/design attributable to the Canton Bridge Co. of Canton, Oh. This is 1 of 3 identified examples (Phase 1B, July 2009),
and it is dated 1910 by the county. It is technologically significant because it represents the era of innovation and experimentation in metal-truss bridge design and an unusual solution to the need for short-span, metal-truss
highway bridges in the late 19th century. Because of deterioration and loss of historic fabric and the alteration of the original floorbeam connection at mid-span as part of its 1987 conversion to a steel stringer in 1987, it has
lost its integrity and no longer meets the NR criteria. A more complete example dated ca. 1890 remains in Holmes County (3841278) and the other in Jefferson County.
