Before the move
How we plan a Mississippi load
Every Mississippi move starts with an MDOT permit. Our permitting team checks the size, weight and route against the Mississippi rules, then sets the escorts and travel windows the permit calls for.
Over 17'W, 121'L or 15'7"H, or at 189,999 lbs, the load is a super load, so we file the route survey and traffic control plan with the application.
Over 120'L we get the railroad letters before the move.
