ABSTRACT:
A deployable modular bridge has a central girder; two side girders flanking the central girder; and couplings connecting each side girder to the central girder along the lower zones of the girders parallel to the bridge length. The couplings are arranged symmetrically with respect to a central vertical longitudinal plane of the bridge and permit displacement of the side girders relative to the central girder parallel to the bridge length. Each coupling includes a rail affixed to the central girder and extending parallel to the bridge length. The rail has a guide track formed thereon. Each coupling further includes a roller mounted on a respective side girder and engaging the guide track.
