It opened to traffic in 1909.","why_significant":"The nomination argues the bridge is an early example of American experimentation with European concrete bridge design and one of only a few non-reinforced, three-hinged concrete bridges built in the United States. It is probably the only remaining bridge of its type open to traffic, and its arch span was the longest of those built. It also reflects City Beautiful Movement civic improvements in small and mid-sized towns.","narrative":"Broadway Bridge carries Broadway across Greenville Creek in Greenville, Ohio, roughly two blocks from the public square. Built of concrete and opened in 1909, it uses a three-hinged arch design, with hinges at the crown and at each springing line. It is 138 feet long with a 120 foot span. Engineers Walter Rice and Albert W. Zesiger designed it, and A.J. Yawger of Bucyrus built it. The three-hinged form came from Germany and was chosen here partly because of soft, spring-undermined ground at the site. The experimental design, its length and the use of concrete drew lawsuits and political controversy that delayed construction. The nomination describes it as one of only a few non-reinforced three-hinged concrete bridges built in the United States and probably the only one still open to traffic. Its decorative railings and balusters also show the City Beautiful Movement's influence on small towns. A recent rehabilitation replicated the original limestone railings.","period_of_significance":"1909-1945","architect_builder":"Walter Rice, Albert W. Zesiger, Designers-Engineers; Builder A.J.
