The New Jersey Turnpike's southbound lanes have reopened after an accident involving two tractor-trailers and a horse trailer in Robbinsville.

The collision happened near Interchange 7A at around 5:15 a.m. State police say one of the tractor-trailers struck the rear of a horse trailer that was being pulled by a pickup truck. The impact pushed the pickup into the back of another tractor-trailer.

The driver of the pickup was flown to Capitol Health Center in Trenton. His condition was not immediately available.

The three horses and one donkey that were in the trailer were taken to a private farm for treatment and were in stable condition.

All southbound lanes were reopened by about 10:30 a.m.
