SR 520 Bridge Replacement and HOV Program - News and updates

Northbound I-5 Fully Closed this Weekend, July 14-15

This weekend, July 14-15, our Revive I-5 contractor crews are Fully Closing Northbound I-5 in south Seattle. Lane reductions for northbound traffic will begin at 8 p.m. Friday, July 13, and wrap up by 5 a.m. Monday, July 16. Multiple ramps will also be closed.

Crews will reduce northbound I-5 traffic to two lanes at the I-405/SR 518 interchange near Southcenter in order to replace an expansion joint on the Duwamish River Bridge. Expect lane reductions to continue all the way up to the West Seattle Bridge/Columbian Way/Spokane Street ramp, where the freeway will fully close and all traffic must exit.

Those coming from West Seattle or Beacon Hill will be able to enter northbound I-5 from the West Seattle Bridge/Columbian Way/Spokane Street on-ramp to head into downtown Seattle. This traffic will shift onto the northbound I-5 collector distributor, where drivers can exit to I-90, James or Madison streets, or continue through to rejoin the northbound I-5 mainline. All lanes will reopen near Olive Way.

Our Revive I-5 online map (pdf 268 kb) has all the scheduled closures.

Why weekend closures?

The short answer is our crews can get a lot more work done during a full weekend closure than during a quick, overnight closure. We did a deeper dive into those details in this Revive I-5 blog. The weekend closures help shorten these major preservation projects, getting commuters and commerce back on Washington’s freeways in a shorter amount of time.

What you can do to help

The full closure of northbound I-5 means there will be heavy traffic on all highways and roads around the region. Travelers should expect long backups on northbound I-405, state routes 99, 509 and 599, as well as on city streets. 

To limit congestion, people should:

  • Use transit, particularly light rail
  • Postpone discretionary trips. Fewer trips means fewer cars and less backup.
  • Travel before 8 a.m., when traffic volume picks up, or after 8 p.m., when it decreases.

Thank you!

There's no way around it, things are going to be challenging. But planning ahead should help take some of the sting out of it. Thank you, as always, for your patience as we complete this critical work on I-5.

Ship Canal Bridge maintenance work on Sunday morning

From 2 a.m. to noon this Sunday, July 15, our maintenance crews will reduce southbound I-5 to two lanes across the Ship Canal Bridge to perform deck-repair work. The Northeast 45th Street on-ramp to southbound I-5 will also close. We want to let folks who live in the area know that the work could be a bit noisy, and apologize in advance for any inconvenience.
