A 10-year-old boy was taken to Tufts Medical Center with serious injuries Thursday after he was struck by a box truck and then a sport utility vehicle while attempting to cross the Middlesex Turnpike in Billerica, police said.
The unidentified boy was trying to cross the southbound lane of the turnpike near Marshall Street around 3:30 p.m. with his mother, said Billerica police Sergeant Sean Coffey.
He was struck by a large box truck and thrown into the northbound lane, where he was then hit by the sport utility vehicle, Coffey said.
The driver of the box truck attempted to stop after hitting the boy, turning the truck sideways and blocking the road, Coffey said.
The boy was taken by MedFlight to Tufts Medical Center in Boston, and officials could not comment on his condition.
His mother was not injured.
State and local police are investigating, Coffey said. There are two crosswalks at the intersection, but Coffey could not say whether the boy and his mother used them.
The Middlesex Turnpike reopened shortly before 7:30 p.m.Amanda Cedrone can be reached at email@example.com.
