Harbor Island, Seattle
Built by the Puget Sound Bridge and Dredging Company, it was completed in 1909 and was then the largest artificial island in the world, at 350 acres (1.4 km2).[1] Since 1912, the island has been used for commercial and industrial activities including secondary lead smelting, shipbuilding and repair, bulk petroleum storage, metal fabrication and containerized cargo shipping.The East Waterway is crossed by a causeway supported a few feet above high tide by pilings.Vigor Industrial operates a 27-acre (10.9 ha) shipyard on the island, which is also the site of some of the Port of Seattle's terminals and the publishing branch of The Mountaineers (Mountaineering: The Freedom of the Hills, among others).The Seattle-Tacoma Shipbuilding Corporation built 45 destroyers for the United States Navy on the island from 1941 to 1946, in a yard now owned by Vigor.
