520 Bridge Replacement
The SR 520 Bridge Replacement and HOV Project will enhance safety and mobility by replacing the aging floating bridge and improving roadway and transit operations throughout the corridor. The 12.8-mile project will result in a six-lane SR 520 corridor replacement from I-5 in Seattle to SR 202 in Redmond.
A WSDOT video shows how the future SR 520 corridor may look and feel once the proposed safety and mobility improvements are completed.
More information about this project is available at the WSDOT project site.
