It was built in 1877 by the Wrought Iron Bridge Company of Canton, Ohio.","why_significant":"The nomination argues it is the only surviving oval tubular arch bowstring bridge in Ohio and one of only three known in the country. It uses William Rezner's patented oval arch and a special shoe from his 1872 patent. It also reflects the work of local figures tied to Ohio bridge building and industry.","narrative":"Carrying a road over Yellow Creek beside Riverside Cemetery in Poland Village, this 127-foot bridge was completed in 1877 by the Wrought Iron Bridge Company of Canton, Ohio. Its single span is a bowstring arch through-truss, with an arch made from oval wrought iron tubes rather than the more usual square or round ones. The oval tube was patented by William Rezner, a Cleveland physician and inventor, and the bridge uses the special abutment shoe covered by his 1872 patent. The nomination identifies it as the only surviving bridge of its kind in Ohio and one of three known nationally. Its length is unusual for the type, requiring three sets of sway bracing. Henry Grant Morse of Poland, who worked for the builder, later founded the Morse Bridge Company in Youngstown. Apart from steel decking replacing wood and added paint, the structure is described as unchanged since 1877, and it remains in use.","period_of_significance":"1877","architect_builder":"Wrought Iron Bridge Co. of Canton, Ohio","architectural_style":"Bowstring arch through-truss with oval tubular arch","criteria":[],"status_note":"Described as in good condition and still in use, though the statement of significance says it is in need of repair.
