They do the same for drills in MS.. I-55, I-59, I-20, I-10, for hurricane reversals... There are plans for I-55, I-20 reversals for NMFZ events. Have hot heard anything about an actual drill for NMFZ stuff yet, but they regularly do Hurricane, and Nuclear Disaster drills. Also in reversal planning for things are US 84, 27, 28, 33, 51, 49 and others. Jackson being the primary Evac hub, along with other Metro areas, including Hattiesburg.
