Traffic is flowing again on Interstate 80 in New Jersey after a truck carrying sheep overturned and set scores of them loose.

The sheep were on their way to a slaughterhouse when they were tossed out of the overturned tractor-trailer near the New Jersey-Pennsylvania line.

Truck driver Marvin Raber told the Pocono Record he was driving from Ohio to New York when he tried to change lanes and his truck flipped over.

It took about four hours before both eastbound lanes reopened through Knowlton.

Some sheep had to be euthanized after the crash.
