At 3 p.m. Wednesday, Dec. 20, WSDOT is opening the SR 520 bicycle and pedestrian trail all the way across Lake Washington. After wrapping up work on the trail the morning of Dec. 20, we’ll open it up to the public that afternoon - in time for a commute home or an evening stroll (bring your rain jackets!).
Until then, watch this drone video or read our latest WSDOT blog post for a sneak peek of the trail and information about how it fits into the regional trail system. We’ll see you out on the trail!

#HumansOf520 featured story: connecting families

With the opening of the SR 520 Trail less than two weeks away, we’re continuing our #HumansOf520 series - weekly stories about community members’ plans for the SR 520 Trail. This week’s #HumansOf520 story comes from Charles Phillips, who is looking forward to using the SR 520 Trail to connect to family and fun in Seattle.

“I have lived in the greater Seattle area for over 27 years and have bike commuted and played on the trails and bike paths for as long as I have lived here. My quality of life has greatly improved over the years because of the ever increasing push to make bike commuting a more viable option. I now regularly commute in and out of Seattle by bicycle; leaving my car at home. I work in south Seattle, I have family that lives in mid Seattle, I love and deeply appreciate the attractions that Seattle has to offer. My preferred mode of transport is always my bicycle. Riding my bike allows me to lower my environmental impact, get my daily exercise in, see family and enjoy the emerald city. The new 520 trail will open a world of exciting opportunities to both Seattleites and Eastsiders; the 520 trail is an attraction all on its own with rest stop/view opportunities throughout the span. Once the path opens I will have shorter commute options, better choices for transit across the lake and I will be able to enjoy evenings in the city without having to worry about waiting for a bus on a late night schedule to get home across the bridge. I am excitedly looking forward to many new adventures with my family and a healthier, shorter, eco-friendly and more relaxing commute.”

24/7 construction hotline deactivation

As we wrap up the current phase of SR 520 construction, we plan to deactivate our 24/7 construction hotline (206-708-4657) within the next two months. (We’ll let you know an exact date when we get closer.) When the hotline is no longer in service, you’ll still be able to call our information line (206-770-3554) during regular business hours, or contact us via email: If crews need to complete nighttime construction work, we’ll provide a hotline for those specific nights.

The next phase of SR 520 construction, known as the Montlake Phase, is scheduled to begin in late 2018. When construction begins, we’ll activate a new construction hotline.
