BOSTON (WHDH) - Motorists heading into Boston were forced to deal with major traffic delays Thursday morning after a tractor-trailer clipped the top of the O’Neill Tunnel, sending debris flying through the air, officials said.

And now the driver, a 59-year-old man from Ontario, Canada, has been ticketed for overheight and overwidth truck, state police say.

Troopers responding to the southbound side of the highway near Exit 20 about 6 a.m. found a pair of disabled vehicles and debris from the toppled truck in the roadway, according to Massachusetts State Police.

Video shared by MassDOT shows several cars swerve out of the way at the last minute as the truck comes to a screeching stop in the middle travel lane.
