Bulloch County 911 is planning a major overhaul of addresses along Northside Drive as a way to make emergency response efforts more efficient. By the start of 2014, nearly every building on the busy highway will sport a new numerical address, according to Kelly Barnard, the director of Bulloch, Evans and Candler County Emergency 911. New numbers are being assigned, she said, because as businesses have moved in each year, more and more inconsistencies have appeared in the system — inconsistencies that can delay a confused ambulance driver or police officer responding to an emergency call.
