Crash Occurs on Northbound I‑5 Near 220th Street On February 4, 2026, a single motorcycle collided on northbound I‑5 near 220th Street Southwest in Mountlake Terrace, Washington, resulting in serious injuries to the rider [1]. Washington State Patrol confirmed the incident involved only one motorcycle and classified the injuries as serious [1].

Initial Traffic Bulletin Overstates Lane Blockage Shortly before 8 p.m., WSDOT issued a traffic bulletin indicating that the crash blocked four lanes of the interstate [1].

Full Restoration of Traffic Flow Completed Tuesday Night By Tuesday night, all northbound lanes near the crash site were reopened, restoring normal traffic conditions on I‑5 [1]. WSDOT coordinated the lane clearance and communicated the reopening to drivers through its traffic alerts [1]. The swift reopening minimized prolonged congestion on a major commuter corridor [1].
