The portable bridge of the present invention includes a plurality of laterally adjacent longitudinal bridging sections, wherein each bridging section extends between longitudinally opposed bridging section supports positioned on opposed sides of an obstacle to be traversed. Each of the longitudinal bridging sections includes a laterally spaced apart generally parallel pair of longitudinal support members for receiving thereon a plurality of decking members in removable resting placement on upper surfaces of the longitudinal support members. Each of the decking members may be removably placed on the upper surfaces of the longitudinal support members so as to extend between the laterally spaced apart generally parallel pair of longitudinal support members, whereby a closely adjacent longitudinal array of the decking members may be placed on the pair of longitudinal support members so as to extend a bridging deck between the bridging section supports. The longitudinal support members include lateral retaining guides for laterally releasably retaining the decking members on the upper surfaces of the longitudinal support members. Transverse bracing members extend between the longitudinal support members. The bridging section supports may be releasably secured to opposed ends of the longitudinal bridging sections. The transverse bracing members may include a pair of transversely extending rigid hollow members, each disposed at opposed ends of the longitudinal bridging sections, the hollow members adapted to be filled with a dense solidifiable filler whereby impact damage to the longitudinal bridging sections is reduced.

Le pont transportable faisant l'objet de la présente invention comprend une pluralité de sections de pontage longitudinales installées contiguës, chaque section de pontage se prolongeant entre des supports de section de pontage longitudinalement opposés, installés de chaque côté de l'obstacle à franchir. Chacune des sections de pontage longitudinales comprend une paire d'éléments de support longitudinaux généralement parallèles, espacés latéralement, conçus pour recevoir une pluralité d'éléments de tablier amovibles et installés de manière amovible sur les surfaces supérieures des éléments de support longitudinaux. Chacun des éléments de tablier peut être placé sur les surfaces supérieures des éléments de support longitudinaux de manière à former un ensemble en longueur entre la paire d'éléments de support longitudinaux parallèles, espacés, latéralement, où un arrangement longitudinal rapproché d'éléments de pontage peut être placé sur une paire d'éléments de support longitudinaux, de manière à prolonger le tablier de pont entre les supports de sections de pont. Les éléments de support longitudinaux comprennent des guides de retenue latéraux pour la retenue non permanente des éléments de tablier sur les surfaces supérieures des éléments de support longitudinaux. Des éléments de contreventement transversaux s'étendent entre les éléments de support longitudinaux. Les supports des sections de pontage peuvent être fixés de manière non permanente aux extrémités opposées des sections longitudinales de pontage. Les éléments de renfort transversaux peuvent comprendre une paire d'éléments rigides creux transversaux chacun disposé aux extrémités opposées des sections de pontage longitudinales, les éléments creux conçus pour être remplis d'un matériau de remplissage dense solidifiable réduisant les dommages d'impact aux sections de pontage longitudinales.
