A truck traveling on I-84 in Newtown Thursday crashed through metal fencing, and then collided with several parked construction vehicles that had been staged in that area.  Sandy Hook Volunteer Fire and Rescue responded to the area of Exit 11 and had to extricate the male driver.  The sole occupant of the truck was unable to move due to the crash, having sustained major injuries.  Firefighters stabilized the vehicle and had to work around the fencing and equipment.  The extrication took less than 20 minutes, and the patient was transported to the hospital.  It then took nearly 90 minutes to remove the vehicle from those it had crashed into.
