A blown transformer is being blamed for a power outage that struck the area near Route 59 late yesterday morning in the town of Clarkstown. Supervisor George Hoehmann says O&R cited the transformer as the reason for the major outage that affected area residents, commercial establishments and traffic lights along Route 59. It took about two hours for most everyone to have the power restored. The outage stretched from Forman Drive in Spring Valley to Route 304.
