ABSTRACT:
A slab-type short span bridge constructed of at least one corrugated plate having parallel, longitudinally extending corrugations of a generally trapezoidal cross-section. A layer of concrete which defines the traffic carrying surface of the bridge and a generally flat plate are secured to the corrugated plate. The flat plate can be interposed between the concrete layer and the corrugated plate, or it may be spaced from the concrete layer by the corrugated plate. The flat plate can simultaneously define portions of the corrugated plate. Means is provided for rigidly interconnecting all members of the bridge into a unitary, load carrying structure.
