ATTLEBORO — Massachusetts State Police are investigating a car-tractor-trailer crash that forced the closure of a stretch of Route 95 south for about 10 hours of cleanup yesterday and the evacuation of 14 homes after the tractor-trailer spilled thousands of gallons of jet fuel on the major thoroughfare.

Route 95 north was also closed through much of the morning. All northbound lanes were reopened before noon. All southbound lanes were open by 3:30 p.m. Residents were allowed to return home once the road reopened, according to the state police.

The police said the 4:47 a.m. crash occurred after an East Providence man driving a 1997 Volvo 960 sedan swerved from the middle lane, where he was driving behind a slower-moving vehicle, into the left lane. Driver Andrew Tavarez, 21, then struck a Jersey barrier on the Reed Street overpass, about a quarter-mile south of the Attleboro weigh station between exits 2 and 3. At that point, he lost control of the Volvo, swerved to the right across all traffic lanes and collided with the driver’s side of the cab of a tractor-trailer in the right lane.

The driver of the tractor-trailer, Michael Cowan, 37, of Northbridge, Mass., lost control of the truck, according to the state police. The tractor-trailer veered left across all three lanes, rolled over and landed on the hood of the Volvo, blocking all four lanes, including the breakdown lane, the police said.

When the police arrived, state police Sgt. David Mahan said Cowan, Tavarez and a passenger from the Volvo, 19-year-old Hope Amaral, of East Providence, were out of their vehicles. All were taken to Rhode Island Hospital with minor injuries, the state police said.

“Everyone involved is certainly lucky,” Massachusetts State Police Trooper Eric Benson said.

At the hospital yesterday afternoon, Cowan was in good condition, spokeswoman Nancy Cawley said. Amaral was treated and released. Tavarez was not treated, Cawley said.

Cowan was transporting 11,001 gallons of aviation fuel from East Boston to T.F. Green Airport in Warwick in a truck owned by C. White Trucking of Connecticut, the police said. About one-third of the fuel spilled onto the highway and flowed toward nearby houses, posing an ignition risk. Emergency crews evacuated about 40 residents on Read Street, Spur Street and Tanya Drive in case the fuel ignited.

The accident, which snarled the morning commute, drew dozens of emergency vehicles and officials, including local and state fire and police crews, fire and police crews from nearby towns, the U.S. Environmental Protection Agency, a hazardous materials response crew from Massachusetts and a fire crew from Green Airport.

Crews monitored the air quality and drinking water in the area, according to James Mooney, health agent with the Attleboro Health Department. The drinking supply and reservoir in Attleboro were not affected, he said.

No charges have been filed in the crash. The state police ask witnesses to contact the Foxboro barracks at (508) 543-8550.
