The accident happened around noon Friday. That's when Lambright, driving a semi with a 53-foot box trailer that contained 43,000 pounds of bottled water, attempted to cross the South Bridge located on South Gospel St. Lambright told Paoli police that she had driven over the bridge before in her personal vehicle and was aware of the posted sign that reads: "No semis, weight limit 6 tons." She also admitted that she didn't know how many pounds that was. The semi she was driving at the time of the accident weighed close to 30 tons.
