Seven people were hospitalized and Route 302 closed for several hours after a morning collision in Bridgton Monday.

Officer Mac McCormick of the Bridgton Police Department said an SUV driven by Margaret Samuelson, 39, of Freeport, was headed west when it went out of control and crossed the centerline at around 9:10 a.m.

The vehicle crossed in front of an eastbound tractor-trailer driven by Matthew Libby, 23, of Porter. The truck jackknifed as Libby tried to avoid a collision and then struck the SUV on the passenger side.

As the cab of the tractor-trailer went off the road, the SUV veered across the parking lot of a local ski shop. Samuelson and six passengers, all minors, had to be extricated from the SUV by the Bridgton Fire Department.

Samuelson’s condition was listed as satisfactory on Wednesday by Maine Medical Center.

Libby and his passenger, Michael E. Dahms, 22, were uninjured in the accident.

McCormick said four of the victims were originally taken to Bridgton Hospital and three to Memorial Hospital in North Conway, N.H. All the victims have since been taken to Maine Medical Center in Portland. Police are not releasing the names of the minors taken to the hospital.

McCormick said the Commercial Vehicle Enforcement division of the Maine State Police joined Bridgton police and fireman in responding to and investigating the accident. He added that the cause of the collision appears to be weather-related and that charges are unlikely to be filed against either driver.
