It was built in 1863 by John Shrake of Newark, Ohio.","why_significant":"The nomination cites the bridge as the last public covered bridge in Coshocton County. It is a surviving example of the multiple kingpost truss, once the most common truss in Ohio's wooden bridges. It is also valued as a picturesque structure in a scenic setting and as work of builder John Shrake.","narrative":"Spanning Killbuck Creek on Township Road 25 at the hamlet of Helmick, this covered bridge was built in 1863 by John Shrake of Newark, Ohio. County records credit Shrake with the superstructure and abutments for $2,107.15, though a stone in the north abutment bears the name F. A. Victor, suggesting a mason helped. The bridge has two 83-foot spans, each with seven panels, joined at a central stone pier. Its multiple kingpost trusses use handhewn timbers pinned with wooden trunnels, and the siding is vertical and unpainted under a red metal roof. Later additions include supports and steel I-beams under the north span, and steel rods beneath both spans. The kingpost was the most common truss in Ohio's wooden bridges. The structure was listed as the last public covered bridge remaining in Coshocton County, and for its scenic setting near a hamlet that once had a sawmill, post office and general store.","period_of_significance":"19th Century (1863)","architect_builder":"John Shrake of Newark, Ohio (builder); masonry possibly by F.
