The Evergreen Point Floating Bridge, officially the Governor Albert D. Rosellini Bridge, and commonly called the SR 520 Bridge or 520 Bridge, is a floating bridge in the U.S. state of Washington that carries State Route 520 across Lake Washington from the Montlake/Union Bay district of Seattle to Medina.
The bridge’s total length is approximately 15,580 ft. Its 7,580 ft floating section is the longest floating bridge in the world.
The Evergreen Point of the bridge’s original name is the westernmost of the three small Eastside peninsulas that SR 520 crosses. (The other two are Hunts Point and Yarrow Point.) In 1988, it was renamed for the state’s 15th governor, Albert D. Rosellini, who had advocated its construction.
