The State Route 520 floating bridge, built in the early 1960s, is vulnerable to wind storms and earthquakes and needs to be replaced. The state Department of Transportation (WSDOT) is planning to replace the span with a one that can better withstand earthquakes and storms. The City of Bellevue and other Eastside cities have endorsed a six-lane alternative, which would include a high-occupancy vehicle (HOV) lane in each direction.
Replacing the floating bridge is just one part of a larger plan called the SR 520 Bridge Replacement and HOV Project , which will result in a six-lane SR 520 corridor replacement from Interstate 5 to just west of Interstate 405.
Another part of this larger corridor plan is the Medina to SR 202: Eastside Transit and HOV Project , which will result in improvements along the approximately three-mile section of SR 520 between Lake Washington and 108th Avenue Northeast in Bellevue. Work will include inside-lane transit stops, community-connecting lids over the highway, a continuous bicycle and pedestrian path that connects to regional pathways, improved interchanges and sound walls. A WSDOT video shows how the future SR 520 corridor may look and feel once the proposed safety and mobility improvements are completed.
