The Lacey V. Murrow Memorial Bridge is a floating bridge that carries the eastbound lanes of Interstate 90 across Lake Washington from Seattle to Mercer Island, Washington. It is the second longest floating bridge on Earth at 6,620 ft (2,020 m), whereas the longest is the Evergreen Point Floating Bridge just a few miles to the north on the same lake, built 23 years later. The third longest is the Hood Canal Bridge, also in Washington State, about 30 miles to the Northwest of the Evergreen Point Floating Bridge.
Along with the east portals of the Mount Baker Ridge Tunnel, the bridge is an official City of Seattle landmark. While the bridge originally had an opening span at the center of the bridge to allow a horizontal opening of 202 feet for major waterborne traffic, the only boat passages currently are elevated fixed spans at the termini with 29 feet of vertical clearance.
