520 Day – thanks for helping us “open” the SR 520 Trail!

Sunday (May 20, aka “520 Day”) was a big day for the SR 520 Program: we officially “opened” the SR 520 Trail across Lake Washington! Thank you to all of the trail users and community members who were there to help us cut the ribbon and celebrate this new community asset. Thanks as well to all of our community partners, including the Cascade Bicycle Club, who were on hand to help recognize the milestone. The SR 520 Trail user counter has registered over 105,000 trips in 2018 – a clear sign of the trail’s popularity and its role as a vital regional connection.

A group of people, some with bikes, stand around a path talking and looking at tables with informational material.

We’ve uploaded pictures from the 520 Day event on our Flickr page. Thanks again to all who stopped by. We hope you continue to enjoy the trail!

U-District StreetFair recap – learning more about upcoming SR 520 construction

We thoroughly enjoyed talking with all those who stopped by the SR 520 booth at this past weekend’s U-District StreetFair. Over the two days, project staff talked to more than 700 fair-goers about prior and upcoming SR 520 reconstruction. Have questions about the upcoming Montlake Phase of construction? Visit our website or read our latest Q&A blog post to learn more!

Heads up: Nighttime geotechnical fieldwork to continue on Friday and Saturday nights, May 25 and 26

Crews were unable to complete their geotechnical work last weekend in Montlake, so they’ll do the remaining work this weekend. Crews will use drilling equipment to bore four holes into the roadway near the intersections of SR 520 and Montlake Boulevard on Friday and Saturday nights, May 25 and 26. They will work Sunday night (May 27) only if needed to finish the work.

To avoid daytime traffic disruptions, WSDOT received a temporary noise variance to complete this work at night. Nearby neighbors may see lights, hear intermittent noise and feel intermittent vibrations from drilling equipment and Vactor trucks. Each boring will also have associated lane closures on East Roanoke Street and 22nd Avenue East. Access to SR 520 and Montlake Boulevard will remain open at all times. Typical work hours will be from 9 p.m. to 8 a.m. each night.

If you have a noise complaint during this work, please contact our on-call representative at 206-200-9484.

West Approach Bridge North Project wrap-up – thank you!

Now that all major construction on the West Approach Bridge North Project has ended, we wanted to take a moment to thank all of you for your engagement with us during the last four years. While you may see crews completing some final wrap-up work in the coming months, we don’t expect any significant construction on SR 520 until late in the year when the Montlake Phase begins.

We’ve come a long way since breaking ground on the West Approach Bridge North in 2014. Our crews rebuilt another section of this vital regional corridor, replacing an aging, vulnerable structure with a new, seismically sound bridge. In addition to building new structures, crews also worked to help restore the arboretum by removing the old R.H. Thomson “Ramps to Nowhere” and a decommissioned westbound off-ramp. With that work now complete on the project, this will be the final WABN email update.

What’s next?

Later this year, we plan to begin construction on the next phase of SR 520 reconstruction, the Montlake Phase. Throughout the summer, we’ll continue to send occasional project updates to this email list – but under a new name and banner: SR 520 Rest of the West News. You don’t need to take any additional action at this time to continue receiving these notices. If you’d like to unsubscribe, you can do so at the bottom of this email. Please be aware that beginning this fall we’ll use this email list for construction notices.

Until then, we hope you have a great summer! Thank you again for your patience and engagement as we work to build a safer and more reliable SR 520. Remember, if you have any questions, you can always reach us on our website, on Twitter, through email, and our information line (206-770-3554).
