No construction planned for this Thursday and Friday

To allow our SR 520 crews the opportunity to rest and spend time with their families this holiday, there are no construction activities planned for Thursday and Friday, Nov. 26 and 27.

Gratitude from the SR 520 team

Many thanks to our project neighbors for your continued patience and understanding during our work to replace the SR 520 highway and build the new Montlake lid. We wish you and your families a healthy and safe Thanksgiving Day (Nov. 26) and Native American Heritage Day (Nov. 27). See recommendations for keeping yourself and your family safe as we enter the holidays in this newsletter from Public Health – Seattle & King County.

Watch our latest video to learn about how crews are removing the old SR 520 bridge

Crews are removing the remaining sections of the old eastbound SR 520 bridge on Lake Washington. Crews are cutting the bridge into pieces and hauling them away, recycling as much of the material as possible. Demolishing the old material away from the lake protects the environment and greatly reduces the noise for nearby residents and local wildlife. Watch our latest video to learn more about this process.

Foster Island Trail tunnel closed Nov. 23 – Dec. 5

From Monday, Nov. 23 through Saturday, Dec. 5, the Foster Island Trail tunnel will be closed. We’re removing the tunnel as we continue replacing the old eastbound SR 520 bridge. Learn more about this work on our construction corner activity page.

Read a summary of public comments from our Portage Bay outreach in September

We hosted a two-week online open house and a virtual meeting in September to get public feedback on three environmental permitting processes for the upcoming Portage Bay Bridge and Roanoke Lid Project. The permitting processes involve a Section 4(f) permit regarding project effects on parks, trails and historic resources, a National Environmental Policy Act reevaluation, and a city of Seattle shoreline permit.  

You can now view a summary of public feedback (pdf 476 kb) from that outreach effort. The summary includes an overview of the three environmental processes and the major comment themes we received from the community. The document also includes our responses to the major comments and questions we received, along with a complete, verbatim list of the individual comments submitted during the online open house. If you missed the Sept. 15 virtual meeting, here is the meeting presentation (pdf 1.7 mb).

Registration now open for virtual Montlake 5K Turkey Trot & Kids Run

The 5th Annual Montlake Turkey Trot has gone virtual, but still has 100% of the fun and community benefits! This year, you can keep the tradition alive by completing the race on your own schedule, indoors or outdoors. Registration is now open and includes a participant bib, face buff and a custom finisher’s medal you can receive in the mail. Graham, the Montlake Project contractor, is a proud sponsor of this great community event. Join Montlake neighbors (virtually) to support the University District Food Bank, which has seen an increase in demand as more people face food insecurity due to COVID-19.

Crews continue working from the SR 520 Trail to make repairs on the underside the highway’s bridge over Lake Washington. Flaggers are present at the work site, and bicyclists and pedestrians on the trail may encounter brief delays.
