Reminder – SR 520 Trail celebration this Sunday!

Making plans for what’s shaping up to be a beautiful weekend? Join us this Sunday, May 20 (“520 Day”), to celebrate the SR 520 Trail! We’ll have a short ribbon-cutting ceremony to “open” the trail, and then you’ll have an opportunity to cut your own ribbon and explore the trail! Read our recent blog post to learn more about the SR 520 Trail, and watch our latest video to see what people are saying about this new regional connection.

Trail celebration details:

  • Date: Sunday, May 20
  • Time: 10:30 a.m. – 12:30 p.m. (ribbon-cutting ceremony at 11 a.m.)
  • Location: The SR 520 Trail’s western trailhead near East Montlake Park (2802 East Park Drive E., Seattle)

Heading to the U-District StreetFair this weekend? Stop by and say hi!

There’s a lot happening in Seattle this weekend, including one of our favorite events of the year – the University District StreetFair! If you’re including the StreetFair in your weekend plans, be sure to drop by the SR 520 booth, located on University Way Northeast ("The Ave") between Northeast 47th Street and Northeast 50th Street. Project staff will be on hand to answer your questions and talk about construction in the corridor – both completed projects and upcoming construction in Seattle. The fair runs from 10 a.m. to 7 p.m. Saturday and 10 a.m. to 6 p.m. Sunday. We hope to see you there!

Plan ahead for travel delays on I-5 and near UW this weekend

Expect traffic delays near UW on Sunday morning, May 20

The 36th Annual Beat the Bridge Run/Walk event will cause traffic delays in the University District and Montlake neighborhoods on Sunday morning, May 20.

Drivers should expect to encounter several road closures between the University Village shopping mall and just south of SR 520 from 7:30 to 10 a.m. If you’re thinking about heading to that area Sunday morning, we encourage you to delay your trip until after the race is over, or expect traffic delays.

The following roads and ramps will be closed:

  • Both directions of Montlake Boulevard Northeast between Northeast 44th Street and Husky Stadium.
  • Both directions of the Montlake Bridge.
  • The westbound SR 520 off-ramp to Montlake Boulevard Northeast.
  • The left turn lanes of the eastbound SR 520 off-ramp to Montlake Boulevard Northeast.

Revive I-5 returns: AVOID northbound I-5 again this weekend!

Revive I-5 work is back in Seattle this weekend, but people throughout the region will need to plan for delays on major highways and city streets Saturday, May 19, and Sunday, May 20.

In addition to northbound I-5, people using I-405, I-90 and state routes 99, 509 and 599 will see heavier traffic as travelers avoid the region’s main interstate. The express lanes will be open in the northbound direction all weekend, which will create backups on southbound I-5 as well.

These closures will allow contractor crews to replace concrete and the left half of nine expansion joints. Our maintenance crews will also repair aging concrete on the Ship Canal Bridge. Here’s a list of what will be closed:

8 p.m. Friday to 5 a.m. Monday

  • Northbound I-5 reduced to two lanes between Michigan Street & SR 520.
  • The Dearborn Street on-ramp to northbound I-5.
  • The northbound I-5 off-ramp to Seneca Street.
  • University Street on-ramp to northbound I-5.
  • Mercer Street on-ramp to the northbound I-5 mainline.
  • NOTE: The Mercer on-ramp to the express lanes will remain open.  However, you will not be able to access eastbound SR 520 from that ramp.

3 a.m. to noon Saturday & 3 to 10 a.m. Sunday

  • Northbound I-5 will remain two lanes between SR 520 and NE 45th/50th Streets.

We saw large backups on northbound I-5 last weekend, and it took drivers at least a half hour to get through the closure area. We hope that if enough people stay away from northbound I-5 – by either taking alternate routes or limiting discretionary travel – we can keep the backups to a minimum.

Even when 50% of vehicles try to avoid the backups and don’t use northbound I-5, all of that traffic has to go somewhere else. So that means that you should expect delays not only on the major highways in the area, but also on Seattle surface streets.

You can help keep these delays from getting out-of-control by:

  • Using public transportation, including light rail.
  • Carpooling or vanpooling.
  • Traveling before 8 a.m. or after 8 p.m.
  • Using alternate routes like state routes 99, 509, 518 and I-405.
  • If you’re traveling to or from the eastside, SR 520 is another alternate route to avoid the long backups near the I-90/I-5 junction.
  • Avoiding discretionary trips.

Next up is the FULL CLOSURE of northbound I-5 scheduled for the weekend of June 1-4, weather dependent. Check out our recent blog for the full list of closure dates so you can know before you go.
