The Washington state Patrol says 24 cars and semi-trucks crashed in an Interstate 90 pile up Thursday morning, leaving 11 people injured.
Trooper Darren Wright says the pile up happened around 11 a.m. near Vantage, Washington. He says there are serious injuries among the 11 people hurt.
The state Department of Transportation says the stretch of the interstate where the accident happened will remain closed until Friday because of poor visibility. The department says wind gusts are kicking up dust left by a brush fire in the rea that burned on Tuesday. There was no time estimate on when the stretch would reopen on Friday.
The department says there's a 15-mile detour using the Old Vantage Highway.
Wright says it's not known yet how the pile up started. It involves 15 passenger cars and 9 semi-trucks.
