Seattle to shut northbound I-5 for Halloween weekend bridge repairs
WSDOT will remove construction zones on the Ship Canal Bridge, closing all northbound lanes from Friday night until Monday morning.
By Jason Kovalenko ·
Northbound I-5 through Seattle will close completely this Halloween weekend. The Washington State Department of Transportation announced that all northbound lanes between I-90 and Northeast 45th Street will be off limits from 11:59 p.m. on Friday, Oct. 30, until 5 a.m. on Monday, Nov. 2.
The closure supports the Revive I-5: Ship Canal Bridge Preservation project. Since summer 2025, crews have restricted northbound traffic on the Ship Canal Bridge to two lanes to repair the bridge deck. This weekend, workers will use the full shutdown to remove the work zone from the two right northbound lanes.
Access changes begin earlier on Friday. Connecting ramps and lanes are scheduled to close as early as 9 p.m. Friday night. Meanwhile, I-5 express lanes will operate as northbound only throughout the weekend, returning to normal schedules on Monday.
The weather remains a key variable for the work. WSDOT stated that removing the work zone requires dry conditions. If rain falls during the weekend, the project may be postponed until crews find a dry window to complete the repairs.
As of Tuesday, the department has not set a makeup date in case the rain forces a delay. Once the work zone is removed, all lanes of the freeway across the Ship Canal Bridge will reopen.
