"We’re asking people to avoid the area at all costs," state police spokesman Lt. J. Paul Vance said, "take alternate routes if they’re traveling to northwest Connecticut to try to avoid this situation....." The crash happened around 4:45 a.m. State police said the truck ran off the right shoulder of the road, crashed through a guardrail and rolled down an embankment.
