Explanation:

[STC002010] The largest man-made island in the United States may be found near Port Seattle, in the state of Washington. Harbor Island is located on the Duwamish River in Seattle, which connects to Elliott Bay. The island was constructed in 1909 by the Puget Sound Bridge and Dredging Corporation out of 24 million yards of dredged dirt from the Duwamish River. The island, which is a component of the Port of Seattle, is utilized not just by business and trade but also by fisherman, who use it to harvest crabs and other shellfish. At the time it was built, Harbor Island had a total area of 350 acres, making it the largest artificial island in the world (increasing to 745 acres in 1967). It has since been eclipsed in size by a great number of other man-made islands across the globe, such as Holland’s Flevopolder, which encompasses a staggering 374 square miles of land area. However, it continues to be the largest in the United States.
