It was built in 1873 by J. C. Davis.","why_significant":"The nomination calls it an outstanding example of a well-maintained Howe truss bridge. It lies in a historically significant area near the grave of Wyandot chief Tarhe the Crane and the Indian Mill memorial. It is one of the few covered bridges left in the area and crosses a section of the Sandusky River in a scenic waterway project.","narrative":"Spanning the Sandusky River about five miles northeast of Upper Sandusky, this covered bridge was built in 1873 by J. C. Davis and is named for nearby landowners. It is a single-span, 16-panel Howe truss, 172 feet long with a clear span of 161 feet 4 inches. The Howe design, patented in 1840, replaced the wooden verticals of the earlier Long truss with adjustable iron rods, an advance that ended the all-wooden truss. The bridge has vertical board siding with battens, projecting portals, stone abutments and a wooden shingle roof, all painted covered-bridge red. It was thoroughly renovated in 1966, including a new roof. The nomination describes it as an outstanding, well-maintained example of a Howe truss and one of the few covered bridges left in the area. It also sits near the grave of the Wyandot chief Tarhe the Crane and within a scenic stretch of river under a state preservation project.","period_of_significance":"1873","architect_builder":"J. C.
