Portage Bay Project updates

Updated Community Construction Management Plan for the Portage Bay Project

Thank you to everyone who submitted comments on the Community Construction Management Plan (CCMP) for the Portage Bay Bridge and Roanoke Lid Project. We’ve updated the plan to include responses to your comments, which you can find at the end of the document and linked on the first page. Please note that the responses in the comments section are organized two ways: thematically (pages 2-33) and by order received (pages 34- 49).

The CCMP is a living document and will be updated annually as construction progresses. You can always reach out to us with questions or concerns via the SR 520 inbox at sr520bridge@wsdot.wa.gov or by calling the Portage Bay Project hotline at 206-319-4520.

First Portage Bay Project construction update meeting on Oct. 15

Skanska, our contractor, will hold their first virtual monthly construction update meeting at 5:30 p.m. on Tuesday, Oct. 15. Join the meeting and learn about ongoing and upcoming construction activities, including staging updates, vegetation removal, upcoming piledriving and anticipated local street traffic effects. Register below to attend.

A Q&A session will follow the presentation. To submit questions in advance, please email sr520bridge@wsdot.wa.gov.


Montlake Project updates

Montlake sign structure update and community engagement report

We’re sharing an update about the sign structures along Montlake Boulevard. As promised, we have produced a report summing up our outreach and engagement process to address community concerns.

WSDOT will contract the Montlake signage work to Skanska, design-builder for the SR 520 Portage Bay Bridge and Roanoke Lid Project. Once contracted, Skanska will need to finalize the design and procure materials. This process will take at least a year, with an estimated completion date of no sooner than summer 2025.

Thank you, again, for your feedback and patience. If you have any questions or concerns, please send us an email at SR520bridge@wsdot.wa.gov.
