Harbor Island is an artificial island in the mouth of Seattle, Washington's Duwamish River where it empties into Elliott Bay. Built by the Puget Sound Bridge and Dredging Company, Harbor Island was completed in 1909 and was then the largest artificial island in the world, at 350 acres . 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. Warehouses, laboratories, and other buildings are located on the island.
Harbor Island was made from 24 million yd³ of earth removed in the Jackson and Dearborn Street regrades and dredged from the bed of the Duwamish River.
