SEATTLE — The driver of a vehicle that crashed in the Mount Baker Tunnel on Sunday is in custody for suspected impairment.
The driver fled on foot after crashing in the tunnel, according to Trooper Rick Johnson. The driver was located at Swedish Cherry Hill.
The crash resulted in a vehicle fire and caused "extensive delays" on westbound I-90 into Seattle, according to the Washington State Department of Transportation.
The crash occurred near Rainier Avenue South in the HOV lane around 4 p.m. All lanes were closed as crews began clearing the scene, leaving some drivers stranded and forcing others to turn around.
Cleanup continued into the evening, with crews needing to intermittently shut down lanes.
Around 8 p.m. WSDOT said crews were still in the process of reopening westbound I-90.
Westbound I-90 fully reopened around 8:40 p.m.
