An intermodal movement of cargo which involves a vessel leg to a port and then a movement via another transportation mode, truck or rail, to an inland point where the movement terminates. In the reverse direction, the cargo is picked up at a point inland for transport via truck or rail to a port where a vessel loads the cargo and transports it to an overseas port. The land portion of the two intermodal moves described is the "microbridge".
