Zusammenfassung:Composite platform for manufacturing road underpasses having monolithic structure. The underpass (10) is advanced through an excavation in the roadway (14), whilst across said excavation there leans at least one central movable plate (20) which, after reaching a preestablished position, is moved back by drive means (36) so that it occupies a substantially central position on the interrupted roadway (14). To said movable plate (20) is joined at least one pair of stationary side plates (24), which provisionally form, together with the central plate (20), the roadbed of the interrupted roadway (14).
