Visit our open houses - online or in person - for the latest on future SR 520 construction in Seattle
Just log in to our online open house now through July 8 to learn about the planned improvements WSDOT will be making to SR 520's west side corridor in Seattle -- the "Rest of the West." You also can join us at our in-person open house on Tuesday, June 28. Both open houses focus on the next phase of west side construction: a new Montlake lid, a "land bridge" over the highway, and the West Approach Bridge South.
The latest bridge-noise updates, including a June 20 noise analysis report and June 13 presentation to the Medina City Council, have been posted on our Floating Bridge and Landings What's Happening Now webpage.
Learn more about removal of the old SR 520 floating bridge from Lake Washington in our decommissioning folio and a June 9 presentation to local mayors. You also can read the project's many environmental reports and permits.
The new floating bridge's bicycle and pedestrian path is expected to open later this summer as an out-and-back trail from Medina. The path will reach Seattle when the West Approach Bridge North is completed in summer 2017. Check out our Bicycle and Pedestrian Connections webpage for more information about riding and walking the SR 520 corridor.
The SR 520 Bridge Replacement and HOV Program is enhancing public safety and mobility by replacing the highway's aging, vulnerable bridges and making significant transit and roadway improvements throughout the corridor. The construction program's planned improvements extend from I-5 in Seattle to I-405 in Bellevue.
