A tractor-trailer carrying glass containers rolled over as it exited Interstate 495 on Thursday afternoon, trapping the two 65-year-old occupants of the truck and prompting authorities to close the ramp between I-495 south and the Massachusetts Turnpike, State Police said.
The occupants had two dogs on board, a Chihuahua that was recovered from the truck and a poodle that ran across the roadway, causing a wild chase and closure of the highway, State Police said.
The trapped occupants, a man and a woman, were freed by the Hopkinton and Westborough Fire Departments and taken to UMass Memorial Medical Center with injuries that were not life-threatening, State Police said.
A preliminary investigation suggested that speed might have contributed to the rollover, State Police said.
Eric Gahagan, a trooper who works with the bomb squad, was driving onto I-495 shortly after the crash and pulled over to help.
To his surprise, he spotted a black poodle running on the ramp.
Gahagan sprang into action, and ran after the dog, hoping to halt what he expected would be an inevitable bad ending. A woman stepped out of a minivan, with a dog on a leash, and joined Gahagan in the attempt to halt the poodle.
Before he knew it, Gahagan said, eight or nine people had exited their cars, stopped all the traffic, and were helping to get hold of the frantic canine.
Gahagan brought his own police dog out of his car hoping to calm the poodle, and with the help of one of the other motorists, managed to grab hold of the pooch, named Princess.
Gahagan brought Princess to the overturned truck, where he learned that she and the Chihuahua, Buddy, belonged to the occupants of the truck.
The dogs weren’t hurt, but are nervous and missing their owners, Gahagan said.
The two dogs are in his custody while the owners recover.
