Traffic on the Maine Turnpike southbound backed up about three miles late Saturday afternoon after a car caught fire in Biddeford.

Maine State Police Trooper Adam Kelley said the car caught fire about 4:25 p.m. just south of the bridge over the Saco River. He said the driver noticed smoke coming through the vents into the interior of the car, pulled over into the median and saw flames when he lifted the hood.

The fire was quickly put out by a fire crew from Kennebunk that was on the turnpike returning from a training exercise and another crew from Saco, Kelley said.

He said traffic was flowing freely again shortly after the car was removed around 5:30 p.m.
