The reinforcing system designed by George M. Cheney consists of an arched metal truss built of angles and gusset plates, separated into vertical panels, and then connected together. The metal truss was built first, then forms were constructed around it and concrete was poured around it. The steel truss becomes embedded in the concrete. The bridge is decorated with Classical Revival elements.〔(【引用サイトリンク】title=Nymore Bridge - Description )〕 The Classical Revival style was part of the City Beautiful movement popular at the time for civic structures.
