Harbor Island was made from 24 million yd3 (18 million m3) of earth removed in the Jackson and Dearborn Street regrades and dredged from the bed of the Duwamish River.[1]
Harbor Island lost its title as the world's largest artificial island in 1938 with the completion of Treasure Island in San Francisco Bay, at 395 acres (1.60 km2). It regained the title in 1967, at which time its area had increased to nearly 397 acres (1.61 km2), but has now been far surpassed in area; since 2004, Rokkō Island in Kobe harbor in Japan is over 3.5 times larger.[1] The official land area, as reported by the United States Census Bureau, was 406.91 acres (164.67 ha), at the 2000 census. There was also a permanent population of three persons reported on the island at that time.
The West Seattle Bridge passes over the island, as does the newer Spokane Street Bridge, a swing bridge across the West Waterway. The East Waterway is crossed by a causeway supported a few feet above high tide by pilings.
