Interstate 55 at West Trigg was flooded around 2 p.m., stopping southbound traffic on the interstate. By 2:45 traffic was flowing smoothly again. Shelby Drive at Millbranch looked more like a river for a while. One person tried to drive on the median and got stuck. Another driver with a truck freed him. John Gillespie, who witnessed the stuck driver, said heavy rain always leads to flooding in this area. “If it’s going to be a downpour we going to have some problems in that area,” he said.
