Seattle commute warning: WSDOT plans full northbound I-5 closure July 10–13

Seattle-area commuters planning to drive north or through the city should treat the weekend of July 10–13 as a major constraint on I-5. WSDOT says northbound I-5 across the Ship Canal Bridge will be in a weekend-long full closure as part of Revive I-5 work zone setup.

SDOT’s travel tips narrow the practical timing further: SDOT says all lanes are open until Friday night, July 10, and then the freeway reopens Monday morning, July 13.

Quick alert: what’s closing, and when

Where: Northbound I-5 across the Ship Canal Bridge in Seattle.
When: July 10–13, 2026 (weekend-long full northbound closure).
Start/finish (resident-facing timing): SDOT says the closure starts after Friday night, July 10, and mainline I-5 reopens Monday morning, July 13.

What drivers should expect during the full closure

Removing northbound capacity at the Ship Canal Bridge can be felt well beyond the bridge itself. KUOW reports that University of Washington traffic engineering professor Yinhai Wang said shutting down part of a freeway causes congestion to spill out through the arterial street network.

WSDOT’s guidance is to plan ahead and build in extra time. If your commute depends on reliable travel times, consider switching to transit if that’s feasible for your schedule.

Express lanes explainer: northbound-only 24/7 (and they won’t reverse)

During lane reductions and full closures connected to Revive I-5, WSDOT says the express lanes run in the direction of the work 24 hours a day. In this phase, that means the express lanes are northbound-only and will not reverse.

WSDOT also emphasizes that some ramps remain HOV-only and drivers should follow posted signage rather than assuming they can enter or exit everywhere.

Practical takeaway: Northbound drivers should plan around express-lane access and exit locations, and southbound drivers should still expect additional delays—because the express-lane directionality won’t flip to help carry southbound traffic.

What changes on Monday, July 13 (and what stays the same)

When the freeway reopens Monday morning, July 13, SDOT and WSDOT describe a shift from the weekend full closure to a reduced-lane configuration (mainline I-5 reduced to two lanes at the Ship Canal Bridge).

But the express-lane rule stays: WSDOT says the express lanes continue northbound-only and operate 24 hours a day throughout the relevant lane-reduction/full-closure periods—without reversing.

What residents can do now

• Give yourself more buffer time for northbound trips through Seattle around July 10–13.
• Re-check your route if you usually rely on express-lane entry/exit patterns—some ramps can be HOV-only.
• Consider transit or schedule flexibility if your commute is time-sensitive; KUOW notes that disruption can worsen early as drivers adapt and find new routes.

Weather can affect the weekend work

Finally, WSDOT warns that these weekend-long full closures for work zone setup or removal are weather dependent. Crews need dry weather to re-stripe lanes, and if conditions are too rainy, WSDOT says work may be rescheduled for the following weekend.

So treat July 10–13 as the planned window—but expect possible updates if weather interferes.
