Portsmouth Firefighters responded to a crash just south of East Main Rd at Sandy Point Ave around 5 PM for a truck vs pole. The three occupants were transported to Newport Emergency Room for evaluation. A Med-Tech rescue was near by and assisted until Portsmouth Fire arrived on scene. The area was shut down as a precaution because the high voltage transmission lines were broken off their insulators. National Grid responded to shut down power to the area and will be on scene for a while.
