A dump truck started spilling gravel and tipped over, stopping traffic in a Boston tunnel.
A dump truck overturned on Interstate 93 north in the Tip O'Neill Tunnel Monday morning, spilling gravel and causing a major traffic backup for commuters Monday morning.
The truck tipped over inside the tunnel on Interstate 93 northbound, just after Exit 23, at about 8 a.m. spilling gravel across three travel lanes, state police said.
Video taken by a motorist showed the driver climbing out of the truck with the help of a motorist.
Police said the driver, a 30-year-old Mattapan man, was taken to Massachusetts General Hospital with non-life-threatening injuries.
Authorities said the Freightliner truck is owned by the Boston Water and Sewer Commission.
Only one lane was open to traffic for a couple of hours where back-ups stretched for miles. By about 10 a.m., state police said the truck and the debris had been cleared.
