Opened to the public in 1938, the Waccamaw River Memorial Bridge is a historic span over the Waccamaw River in Conway, South Carolina. It was designated as a memorial bridge to commemorate the citizens of Horry County who served in the past wars for the United States, from the American Revolutionary War to the First World War.

Measuring 1270 feet long, the Waccamaw River Memorial Bridge is also significant for the engineering techniques used in its construction. It employed the methods used by the South Carolina highway bridges whose styles were making strides around the time. Some of its most notable elements are its long vertical and horizontal curves, Gothic-influenced pointed arches, and 28 cast iron light standards on the balustrade.
