The Massachusett Department of Transportation is reporting that the 495 North entrance from 290 East has been blocked.
The block has closed the ramp to 495 North at exit 26 A/B after a car carrier rolled over.
The Marlborough Fire Department was called to the scene. There were no injuries reported, but they were called in to deal with a small fuel spill, said fire officials.
Marlborough Deputy Fire Chief Fred Flynn said during a closure of 495 North in August that tractor trailer accidents on this ramp happen at least once or twice a year.
