UPDATED: Accident closes I-95 in Sidney

SIDNEY -- A LifeFlight helicopter has airlifted a subject injured in a motor-vehicle accident on Interstate 95 in Sidney.

A U-Haul truck pulling a car overturned and caught fire just south of exit 120 on I-95, according to Maine State Police broadcasts.

The truck was traveling northbound in the passing lane and apparently veered into the median. It rolled over after traveling 40 to 50 feet, said Gerry Bechard, who saw the accident while driving on the Lyons Road, I-95 overpass in Sidney. The car pulled by the truck did not overturn, he said.

The accident happened at approximately 1:45 p.m., said Bechard, of Sidney.

"The truck's pretty well toast," he said in a telephone interview at 2:30 p.m. "It's still smoking. I can see it right now."

Bechard said he called 911 to alert police to the accident. A LifeFlight helicopter arrived to transport the accident victim. The chopper left the scene at approximately 2:20 p.m., Bechard said.

The accident caused a traffic backup of more than three miles, but Maine State Police have reopened one northbound lane.
