Abstract
A temporary bridge for supporting heavy loads includes elongate hollow cylinders. A first rigid flat plate is horizontally disposed in overlying relation to each hollow cylinder and a second rigid flat plate is horizontally disposed in underlying relation to each hollow cylinder. Stress-distributing strengthening members formed by a pair of legs that are angularly disposed with respect to one another are circumferentially positioned about each hollow cylinder and the respective free ends of the legs are secured to their associated rigid flat plates. A key extends from a first end of each hollow cylinder and a mating socket is formed in a second end of each hollow cylinder to facilitate end-to-end interconnection of a plurality of hollow cylinders. Further embodiments include longitudinally-disposed timber mats, pedestrian walkways and curvature-creating members so that the bridge may follow a non-linear path of travel.
