SR 520 Portage Bay Bridge Designs

SR 520 Portage Bay Bridge Cable Stay design concept - Portage Bay and Roanoke Neighborhood from Montlake Playfield

As part of the SR 520 Seattle Community Design Process, we are continuing to identify potential design refinement opportunities for the new SR 520 corridor in Seattle.

We are introducing three design concepts for the SR 520 Portage Bay Bridge: a box girder bridge, an extradosed bridge, and a cable stay bridge.

We encourage your feedback and ideas. Send us a message at: SR520CommunityDesign@wsdot.wa.gov.
