PORTLAND — Interstate 84 between La Grande and Pendleton has been closed because wintry weather has caused many vehicles to spin out and block the roadway.

The Oregon Department of Transportation said Tuesday morning the eastbound lanes are closed for about 20 miles north of La Grande to the Meacham area, where vehicles blocked the highway.

The westbound lanes were closed from about 7 miles east of Pendleton to the Meacham area.
