The Thruway ramp was closed Thursday morning for about three hours as the result of an accident. Around 7:40 a.m., a tractor trailer flipped while exiting the eastbound roadway at exit 59, the Dunkirk/Fredonia exit. Both the entrance and exit ramps were closed as firefighters freed the driver, Magdala Laguerre, 33, of Hillside, N.J., who was trapped in the cab. She was taken to Brooks Memorial Hospital for a wrist injury and bruises and contusions to the body. According to police, she may have been traveling too fast on the exit. Charges are pending.
