A variably dimensionable bridge (10) comprising pre-engineered components provided in a kit. The pre-engineered components are constructed of fiber reinforced polymer (FRP) composite material and include at least one floor module (14) for providing a floor; at least two girders (12) for providing opposing substantial vertical sides; and at least two cross beams (16) to lend support to the girders (12). A is a method for constructing a bridge (10) of variable dimensions comprising the use of pre-engineered components provided in a flat-pack kit.

A modular ramp system includes a ramp component and a connector releasably joined to the ramp component. The ramp component has first and second inclined surfaces and a connecting portion positioned between the first and second inclined surfaces. The connector has a bottom side formed with a first and second coupling section connectible to the connecting portion. The connector is positionable in a first position in which one of the first and second coupling sections is releasably joined to the connecting portion of the ramp component and the other of the first and second coupling sections is adapted to releasably couple to a ramp or an external structure, and a second position in which the first and second coupling sections are releasably joined to connecting portion of the ramp component.

Portable road segments, herein referred to as surface vehicles, include first and second surface vehicles. A female wedge mount is attached to the first surface vehicle. The female wedge mount has a concave contact surface including three or more female contact surface segments an at least two female wedge slots. A male wedge mount is attached to the second surface vehicle. The male wedge mount has a convex contact surface including three or more male contact surface segments and at least two male wedge slots that are aligned with the at least two female wedge slots, respectively, when the convex contact surface of the male wedge mount and the concave contact surface of the female wedge mount are in aligned contact with one another to form an adjacent connection between the first and second surface vehicles. A mechanism includes at least two pins that are movable along the at least two male and female wedge slots, respectively, between unlocked and locked positions.
