DETROIT (AP) — A major interstate ramp near downtown Detroit reopened Tuesday after a livestock trailer with 38 cows overturned, forcing authorities to euthanize some animals.

The trailer crashed Monday when the driver was on a southbound Interstate 75 ramp from I-94, state police said.

Authorities cut a hole in the trailer to get access to the cows. It took hours to clear the scene. Some animals had to be euthanized.

“Sometimes it's the most humane thing you can do,” state police Lt. Mike Shaw told radio station WWJ. “Unfortunately we get stuck with that quite often” with car-deer crashes.
