It is the last original covered bridge in Franklin County and one of only six surviving examples of the Partridge truss. It also reflects the link between the truss inventor and the bridge company that built it.","narrative":"Spanning Little Walnut Creek one mile south of Canal Winchester, this covered wooden bridge was built in 1887 by the Columbus Bridge Company for $2,690. Its single span runs about 119 feet between cut-stone abutments laid by M. Corbett. The oak trusses follow the Partridge design patented in 1872 by Reuban Partridge, who was an officer in the bridge company at the time, which likely explains the choice. The bridge has cedar shingles, vertical white pine siding left unpainted, and red-painted portals. It sits on its original site, near the old Kramer's Ford, and was part of a state route from the late 1930s until the road was relocated in 1956 and the bridge returned to county ownership. It is the last original covered bridge in Franklin County and one of only six Partridge truss examples known. The county engineering department maintains it and has placed historical signs over each portal.","period_of_significance":"19th Century (specific date 1887)","architect_builder":"Columbus Bridge Company; abutments laid by M.
