The South Park Bridge is a double-leaf bascule bridge in Seattle, Washington, United States. Opened in 2014, the current bridge replaced a 1931 bascule bridge that carried the same name and had been listed on the National Register of Historic Places. The bridge is operated by the King County government. It carries automobile traffic over the Duwamish River near Boeing Field, just outside the city limits of Seattle, and is named for the nearby South Park neighborhood of Seattle.
