Westbound state Route 16 near Union Avenue was closed early Sunday morning after a pedestrian tossed nails onto the freeway, according to the Washington State Patrol.
The incident was first reported just before 8 a.m.
“Troopers and state Department of Transportation crews are on scene attempting to clear a large amount of nails strewn across multiple lanes on WB SR 16 west of Union,” Trooper John Dattilo said via social media. “A sweeper truck is en route, but it will be a while before the road can reopen.”
He added that the pedestrian has been arrested on suspicion of first-degree malicious mischief.
