Two people were killed and two others were injured in a multi-vehicle accident on Interstate 495 in Westford this morning, State Police said.
Authorities described a cascading series of crashes near Exit 32 around 6:30 a.m.
A Honda CRV being driven by Henry X. Obrien III, 40, of Templeton, was traveling south on the interstate in the left-hand lane when it was rear-ended by a Chevrolet Malibu operated by John J. Cousineau, 21, of Worcester. The force of the collision made the Honda veer left, cross the median. It was subsequently struck by a Dodge Caravan driven by Joseph P. Dainis Sr., 40, of Leicester, which was traveling northbound on the interstate.
The Honda then was hit by a tractor-trailer operated by Joseph Poirier, 48, of Hopedale. The Honda flipped over.
The two occupants of the Honda, Obrien and his passenger Gregory E. Butler, 46, of Fitchburg, were taken to Lowell General Hospital and Emerson Hospital where they were pronounced dead.
Dainis and Cousineau were taken to Lowell General and Emerson Hospital for minor injuries.
All northbound lanes and one southbound lane of I-495 were closed for three hours, and were reopened at 9:30 a.m.
