The bridge laying system incorporates one or more vehicles with laying mechanisms. Bridge sections of inverted U-section and with parallel girders are joined together and pushed in the longitudinal direction of the vehicle. They include two ramps and a leading end supporting part, travelling on roller guides in the longitudinal direction. At the bridge section girder bottom corners, facing each other, are guide rails (16), in which rollers (15) on the laying mechanism (8) engage. A drive mechanism (23) is coupled alternately to the bridge sections and the support and the support part portions.
