Abstract: A barrier device capable of rapid deployment and assembly to form a barrier wall. The barrier device comprises wheels so as to be easily transported. The barrier device further comprises connection plates so that adjacent barriers can be connected to one another quickly and without the use of any tools or other components. In one aspect, the invention is the barrier device comprising: base plate structure having a top surface and a bottom surface, the bottom surface of the base plate structure being in a first plane; a wall plate structure connected to and extending upward from the top surface of the base plate structure; and at least one wheel having a tread surface, the at least one wheel positioned so that the tread surface of the wheel is at or above the first plane and at least a portion of the tread surface extends beyond the rear edge of the base plate structure.
