Before the move
How we plan a South Dakota load
Every South Dakota move starts with a single trip oversize and overweight permit. Our permitting team checks the size, weight and route against the South Dakota rules, then sets the escorts and travel windows the permit calls for.
Over 16'H, over 200,000 lbs, or overweight and wider than 12', the permit goes to a longer state review, so we file early. Every vertical clearance on the route is ours to check before the move.
Our 22 axle setups carry loads up to 300,000 lbs.
