The Jerome Street Bridge is an arch bridge across the Youghiogheny River connecting the east and west banks of the Pittsburgh industrial suburb of McKeesport, Pennsylvania. The bridge is a rare steel crescent arch bridge. A crescent arch is formed when the intrados and extrados (the ribs) of the arch are not parallel, but instead form two different curves beginning and ending together. The ribs form a truss at the top of the arch and join together in a solid rib at each end. A crescent arch is a two-hinged arch, the ribs are further apart where the bending moment is greatest and close together at each hinge where it is minimized.
