Arlington Memorial Bridge and its related architectural, engineering, sculptural and landscape features are significant as important elements in the neoclassical urban design of the National Capital as it evolved during the first third of the 20th century. Successfully integrated with Washington's grand plan, the bridge composition enhances the monumental city as well as the riverscape. The low, neo-classical bridge is 2,163 feet long ant 90 feet between balustrades, carrying a 60-foot-wide roadway and 15-foot sidewalks. Nine broad arches cross the river; roadways pass through additional segmental-arched openings at either end. Except for the central bascule draw span, the bridge is of reinforced concrete construction faced with dressed North Carolina granite ashlar. The draw span is of the double leaf, underneath counterweight type and is faced with pressed ornamental molybdenum steel to blend with the masonry spans. Once one of the longest (216 ft.), heaviest (3000 tons), and fastest (one minute) such draw spans in the world it is now sealed and inoperative.
