SR 520 email update - May 22, 2012
Driver alert: SR 520 bridge and highway closed eastbound May 22 and May 23; westbound closed May 30
Plan ahead for Eastside construction closures as crews close a single direction of the SR 520 floating bridge and highway from Montlake Boulevard to 92nd Avenue Northeast overnight on May 22, 23 and 30.
During the closures, crews will perform utility work over the highway lanes at 84th Avenue Northeast. Additional work will be performed throughout the corridor to take full advantage of the closure. This work is part of the Eastside Transit and HOV Project.
Closure details:
- Eastbound lanes close 11 p.m. to 5 a.m. overnight May 22 and 23
- Westbound lanes close 11 p.m. to 5 a.m. overnight May 30
Two SR 520 drawspan openings scheduled May 22, one early May 23
Head's up: the SR 520 drawspan will open for boaters at 7:30 and 8:30 p.m. tonight, May 22, and at 5 a.m. tomorrow morning, May 23.
Did you know you can receive email alerts or text messages (or both) one to two hours before each SR 520 drawspan opening? Here’s how to sign up:
- Go to our email alert system page.
- Enter your email or cell phone number. You’ll be able to sign up for drawspan alerts for both email and text messaging.
- Sign up for the new alert called “520 Bridge Opening” from the subscription list (located under the “Traffic and Travel Updates” section). You’ll have to sign up separately for text message or email alerts.
When a drawspan opening is scheduled, you’ll receive two alerts: First, an alert one to two hours ahead of the opening (depending on how much advance notice is given). Then, another one 30 minutes before the opening.
You can always find scheduled drawspan openings on our marine page and our What’s Happening Now page.
Plan ahead: next full weekend closure June 1-4
The next full weekend closure will occur June 1-4 when crews close all lanes and ramps between Montlake Boulevard and I-405.
During this closure, crews will demolish the existing 92nd Avenue Northeast overpass, remove the last standing piece of the old Evergreen Point Road overpass and swing 34 girders into place for the new Evergreen Point Road lidded overpass.
