With a main span of 471 m (1546 ft.), this bridge is the longest cable-stayed bridge in North America. The new, award-winning bridge replaced two aging truss bridges over Cooper River and Town Creek, and increased the capacity from five to eight lanes of traffic. Seismic and wind demands were both stringent as the bridge is located in a hurricane zone and its site has one of the highest seismic demands in North America.
