Whatcom County, WA (September 1, 2025) – A serious two-vehicle crash shut down part of Interstate 5 in Whatcom County late Sunday, August 31, leaving at least one person with major injuries. Washington State Patrol confirmed that the crash occurred near Zell Road in Custer around 11:30 p.m. Trooper Kelsey Harding reported that two vehicles collided in the southbound lanes, forcing all lanes to close for several hours.

The Washington State Department of Transportation redirected traffic off I-5 from the Birch Bay-Lynden Road interchange to the Grandview Road interchange through Portal Way. Emergency responders provided aid to those injured, with at least one victim transported to a nearby hospital for treatment. The exact number of injured parties remains unconfirmed, but authorities classified the wreck as a serious injury collision.

Towing crews removed the wrecked vehicles, but debris cleanup kept lanes closed until early morning. Investigators are examining the crash site to determine the cause.

Our thoughts remain with the injured, and we wish them a full recovery.
