FAIRFIELD — A car driven by a Fairfield woman was destroyed Tuesday afternoon after it burst into flames on Route 139 in Fairfield.

The woman, Margaret Genest, 66, was driving up the Pung Hill section of the highway, which is Norridgewock Road, near the Waterville city line, when the incident occurred, Fairfield police Sgt. Paul St. Amand said.

Genest said the car was not accelerating normally and she pulled off to the side of the road. A moment later, she said, she saw smoke followed by fire coming from under the hood.

“That’s when I decided to get out,” Genest said.

Genest was alone in the car, a 2006 Buick Lucerne, and was not injured. Fairfield firefighters and Delta Ambulance also responded to the emergency.

St. Amand said the nose of the car was ablaze when he arrived and the Fire Department managed to extinguish the flames before fire could engulf the car’s interior.

The road was closed in both directions and traffic was backed up for about 35 minutes, St. Amand said.

He said the fire’s cause is unknown.
