Update, 10:10 a.m.: Crews are continuing to clean up debris from the rollover, but the ramp between I-290 East and I-495 North is now open.
A tractor trailer rolled onto its side on the ramp from I-290 East to I-495 North in Marlborough, forcing officials to close the ramp down while they cleared the scene. Commuters should expect heavy delays.
Crews began working to clean up debris from the accident, including some of the truck’s cargo that spilled out. Massachusetts State Police Trooper Dustin Fitch was tweeting images from the clean up effort.
