Maine State Police are investigating a collision involving two vehicles on I-95 near Lincoln that sent one person to the hospital early Sunday evening.

State Police, Lincoln Police and Lincoln Fire Department responded to the crash in the southbound lanes around 5:30 p.m.

Witnesses said one car rolled over several times and ended up on its roof straddling the breakdown lane and the travel lane. Another vehicle - an SUV - also rolled and ended up off the highway.

One person was reported to have been transported by Lincoln Ambulance to Northern Light Eastern Maine Medical Center in Bangor with unknown injuries. It’s not clear if anyone else was injured in the crash.

Traffic in the southbound lanes around exit 227 was backed up for a time, and was opened to just one lane during the evening hours.

State Police are investigating. They say the driver of the SUV apparently fell asleep at the wheel and rear-ended the car.

WABI reports two dogs were thrown from the car as it rolled over. One of the dogs ran to a State Police cruiser that was parked off the highway. The trooper secured the dog and was alerted to the crash when he heard a man yelling for help.

The Lincoln Police Department reported on Thursday that a Doberman pup named Bentley that was thrown from the car in the rollover, was found safe and returned to his owners on Thursday morning.
