BAKER CITY, Ore. (AP) - Oregon highway officials said they partially reopened Interstate 84 in eastern Oregon after being closed for most of Saturday following a massive crash.

Twelve people were injured in the accident involving more than a dozen tractor-trailers. None of the injuries are believed to be life threatening.

More than 160 miles of eastbound lanes were closed from Pendleton to Ontario, as crews worked all day to remove cars, trucks and debris from the road.
