A triple-helix horizontal spanning structure comprised of three helical beams in compression and cables in tension which integrate with the helical compression members and together form a structure that is stable. Anchored at each end, the structure is a single-span structure without any intermediate vertical members such as columns or pylons. This super structure provides a longitudinal space for the sub structure to be hung within the helical beams and cables that can serve as platform for such things as roads or passageways. |
