The Whirlpool Rapids Bridge, commonly called the Whirlpool Bridge, and until 1937, known as the Lower Steel Arch Bridge, is a spandrel braced, riveted, two-hinged arch bridge. It crosses the international border between Canada and the United States, connecting the commercial downtown districts of Niagara Falls, Ontario and Niagara Falls, New York. This bridge is located approximately 1.5 kilometres (0.9 mi) north of the Rainbow Bridge and about 2 kilometres (1.2 mi) from the Falls. This bridge was acquired by the Niagara Falls Bridge Commission in January 1959.
