KIRKLAND, Wash. - A drywall spill blocked lanes of southbound I-405 in Kirkland for several hours, backing up traffic 4.5 miles. It has since reopened.
Investigators are still working to figure out how the spill happened, but say no one was injured. The right three lanes of southbound 405 were blocked by sheets of drywall and dust, and crews were called in to clean it up.
Pictures taken by Washington State Patrol show the rear trailer of the truck flipped upside down.
Traffic was reduced to just two lanes, and the Washington State Department of Transportation’s traffic map showed backups extending up to 160th St, south of Woodinville – roughly 4.5 miles.
