A tractor trailer delivering a food shipment for the Bangor school district tipped over on Macaw Road in Bangor. The driver had pulled over to check his directions when the wet ground gave out.”The ground just gave way from underneath my truck, and it slid me into the little drain ditch causing a slow rollover so it just stopped. It tipped over,” said Antonio Serna, of G&J Transport.Serna was carrying the truckload of refrigerated food to Dennis Paper and Food Service just up the road from the accident. Bangor Police expected it to take a few hours to transfer the food to another truck. No one was injured.
