A method of distributing freight between an intermodal shipping container and the freight containers of one or more surface-road transports, comprising the steps of: providing a freight container of at least a first surface-road transport; providing a first intermodal shipping container containing freight having a collective weight in excess of the maximum weight that can be lawfully carried in the freight container of each surface-road transport; providing a selectively moveable cross-dock having a body defining an interior storage area and at least first and second openings in the body through which freight may be moved into and out of the interior storage area; positioning a loading/unloading opening of the first intermodal shipping container proximate one of the openings in the cross-dock; positioning a loading/unloading opening of the freight container proximate the other opening in the cross-dock; and distributing freight between the intermodal shipping container and the freight container via cross-dock, the distribution step not continuing beyond the point at which the collective weight of all freight in each freight container would cause each surface road transport to exceed the maximum lawful surface-road transportation weight.
