SEATTLE: Expect significant overnight closures on I-5 through downtown and Northgate

SEATTLE: Expect significant overnight closures on I-5 through downtown

We roll into February with a series of significant closures on the construction calendar for our I-5 Seneca project as we improve mobility through downtown Seattle. 

The closures mean the northbound mainline lanes and the collector/distributor lanes of Interstate 5 will close. Northbound drivers can proceed into the Express Lanes keeping in mind they will not be able to exit until NE 42nd St near the University of Washington. 

Drivers who want to access downtown Seattle can exit at Edgar Martinez Drive or Rainier Avenue. This closure is planned nightly from 11:59pm Wednesday, February 15 to 4am Friday, February 17, and again nightly from 11:59pm Wednesday, February 22, to 4am Friday, February 24, 2023.

Next week drivers can plan for a typical construction pattern for this project as traffic shifts over to the collector/distributor lanes nightly from 9pm Monday, February 6, to 5am Friday, February 10.

Work this week includes:

• Drivers should plan for nightly southbound lane reductions near I-90 from as early as 10pm Monday, February 6, through 5am Friday, February 10.

Various ramp closures will occur during late-night work including Olive Way, Madison, Union, Spring, James, Yale, Cherry and University streets.
