Abstract: A transportable pantograph truss bridge structure. The pantograph truss is in the form of an inverted triangle with deck sections incorporating gratings utilized as parallel tracks for wheeled vehicles. The bridge is suitable for rapid deployment in military applications and is portable on a wheeled trailer including erecting masts, cables, and winches. The pantograph truss is formed of sealed tubular elements, so as to be neutrally buoyant. The deck panels are formed in sections with grating formed of metal or of resin impregnated Fiberglas, carbon filaments or the like.
