Before the move
How we plan a Washington load
Every Washington move starts with a WSDOT permit. Our permitting team checks the size, weight and route against the Washington rules, then sets the escorts and travel windows the permit calls for.
Over 14'6"H our lead escort runs a height pole on every highway on the route.
Superloads go in early, because WSDOT needs time to analyze the bridges and pavement on the proposed route.
