WALTHAM, MA - Around 9:45 A.M. on May 15th, both Waltham and Weston Fire Departments were receiving calls for a truck rollover on the off ramp from I-95 south to Route 20 in Waltham. Weston Engine 4, Ladder 1 and Ambulance 1, along with Waltham Engine 4, Squad 5, Rescue 1 and Medic 1 responded. Companies arrived and found an 18 wheeler tipped over on its side with a load of gravel dumped out, and the driver still pinned inside the tractor. It took firefighters 30 minutes using the Jaws of Life to extricate the driver, who had a broken leg and was taken to Lahey Hospital in Burlington.
