Abstract: Bridge comprising a bridge floor, said floor consisting of an upper boom (4) which may form a road section, a lower boom (5) which may be formed by a tubular succession of sections, and diagonal linking girders (6), joining the booms, their axes converging on that of the lower boom. Those elements subjected to high stress are preferably to be provided with individual pretensioning elements. The gussets (15) linking the diagonals with the upper boom carry advantageously the attachment elements of the supporting stay cables (2).
