ABSTRACT:
A transportable bridge having longitudinal sides, includes plural bridge sections connected in series and presenting first and last bridge sections in the series. Each said bridge section in the series includes a deck slab extending across a width of the bridge and having front and rear transverse ends, and an inverted triangular truss on each longitudinal side of the bridge. Each truss has a lower corner portion and an oppositely disposed top beam. The lower corner portion of the truss is connected to the rear transverse end of the deck slab and additionally to the front transverse end of the deck slab of an adjacent following bridge section in the series of bridge sections. The top beam of the truss of the bridge section is connected to the top beam of the adjacent following bridge section thus forming a trough-shaped bridge having a lateral truss structure. A further deck slab is associated with the last bridge section. Diagonal struts are connected, respectively, between the top beams of the trusses of the first and last bridge sections and the deck slabs associated with the first and last bridge sections for closing off the trusses.
