Before the move
How we plan a Maryland load
Every Maryland move starts with an MDOT SHA hauling permit. Our permitting team checks the size, weight and route against the Maryland rules, then sets the escorts, pole car and travel windows the permit calls for.
Maryland tunnels and toll bridges have their own limits, so we route wide and tall loads to avoid the Harbor and Fort McHenry tunnels.
Superloads over 150,000 lbs need an engineering review and police escorts, so we file early.
