Friday's freezing temperatures and iced over bridges landed a number of south Mississippi motorists in harm's way. The wintry weather took many people by surprise, resulting in dozens of accidents and even a few pile ups. Kelly Castleberry, M.D.O.T. District Engineer, says, "Friday’s was a non-forecast event. Temperature was supposed to be warmer and precipitation was supposed to be drier." More wintry weather is on the way and this time, M.D.O.T. is getting ahead of the curve. At noon, 300 workers hit the pavement, prepping major highways for frozen roads and icy conditions. They cleaned up road salt and sand left over from this weekend's weather event in preparation of spreading out fresh sand and salt tonight. Castleberry also says, “Some of these are a highly concentrated salt water solution that we're applying and when it’s dry, we let the water evaporate, leaving the salt behind. We have spreader trucks that will put a sand salt mix out and some with just a sand mix.” M.D.O.T. has 35 de-icing trucks working throughout Mississippi's lower 14 counties, all preparing for tomorrow’s weather. Castleberry closes, “If you can avoid being on the road, you really don't need to be on there when the precipitation starts.” Staying off the roads is the only guarantee you won't end up in a wreck. M.D.O.T. workers will be working around the clock the next few days, so if you find yourself out on the road, keep an eye out for them.
