ABSTRACT:
A hybrid bridge construction comprises a pair of piers enclosed in the earth at a fixed predetermined distance apart with a cantilever section supported on each pier. Each cantilever section comprises one or more vertical towers with a pair of inner and outer rigid compression members fixed to and extending upwardly and outwardly from the base of each tower. Outer tension members are attached to the top portions of each tower and to upper end portions of the compression members. A suspension section interconnecting the cantilever sections comprises catenary cable members attached to the upper end portions of inner compression members. A road deck extends between the piers, and vertical suspender members extend between the cable members and the road deck.
