Smith Road Bowstring Arch Bridge, Spanning Sycamore Creek at Smith Road (TR 62), Lykens, Crawford County, OH

Significance: This is the oldest bridge in Crawford County, Ohio. It also provides a prime, existing example of a wrought iron tubular arch design, patented by Zenas King of Cleveland's King Iron Bridge and Manufacturing Company in 1861 and improved upon in 1867. The patenting and manufacturing of the prototype of this design, among the first in the United States for an iron bridge, launched the career of this bridge designer and builder. The bridge, listed on the National Register of Historic Places as the Smith Road Bridge, is scheduled to be replaced in 1991. Federal aid has been requested to fund the replacement.
