Plan ahead - Weekend closures of Lake Washington Boulevard next month

We’re closing Lake Washington Boulevard on multiple weekends next month in both directions between East Foster Island Drive in the Arboretum and Montlake Boulevard. These closures will give crews room to install drainage pipes. We will close the street during the following weekends: June 12-13, June 19-20, and June 26-27. We will provide more information as the work approaches.

Get ready for big changes with Good To Go!

Next month Good To Go!, the state’s tolling system, will be upgrading to a new and improved customer service and billing system. It will feature several things customers have been asking for, including more self-service options, text alerts, and removing the requirement to pre-pay $30 in tolls when opening an account.

While the transition is underway the current system will be offline for approximately two weeks. That means drivers won’t be able to pay bills, access their accounts, or contact customer service during that time.

Check out our new blog and system upgrade page for everything you need to know!

Closures of the bike and pedestrian path under SR 520

To enable construction truck and equipment access to the new eastbound SR 520 bridge that’s under construction over Union Bay, we will intermittently close the temporary bike and pedestrian path under SR 520 between Lake Washington Boulevard East and East Park Drive East. These closures will occur until Wednesday, June 16. Please continue to check the Construction Corner, as well as on-site signage, for closure information.

Heads up, night owls: overnight, directional SR 520 closures June 2 and 3

Plan ahead! Crews will fully close one direction of SR 520 across Lake Washington the nights of June 2 (eastbound) and June 3 (westbound) to work on the underside of the Montlake lid. Please check the Construction Corner and stay tuned as we share more details in the coming weeks.

Next step for the former Montlake Market and 76 gas station property: contamination cleanup

As you may know, when WSDOT acquired the former Montlake Market and 76 gas station property, we committed to cleaning up contamination on the site. Since acquiring the property in 2019, we’ve enrolled the property in the Department of Ecology’s Voluntary Cleanup Program. To prepare for the cleanup, we’ve completed site investigations, agency coordination, and construction planning.

Now we’re looking forward to starting the major remediation work as early as this summer. In the next several weeks, crews will begin by removing the remaining structural foundations of the old market and gas station buildings. Crews will then remove the old underground tanks. Removing contaminated soils will require in-street excavation (beyond the property limits) and is expected to take place during the SR 513 Montlake Bridge closure Aug. 9 – Sept. 2, 2021. Conducting the in-street work during the Montlake Boulevard closure will reduce the number of road closure days and reduce the impact construction has on our community.

Check out our most recent blog post to learn more about the planning and preparation for cleanup, including the contaminants, the safety of the community and environment, phases of cleanup activities, project funding, and the future of the former Montlake Market and 76 gas station property.

As the work gets closer, we’ll have more details about what neighbors can expect. If you have any questions, please contact us via email, Twitter (@WSDOT_520), or phone (206-770-3500).
