Abstract of the Disclosure This invention relates to an arrangement for projecting cantilever sections of multi-sectional bridge supporting structures forming the super- structure of the bridge which is supported on bridge piles. A traveling auxiliary beam is movably carried on and arranged above the superstructure for spanning between superstructure sections. Two concreting scaffolds each comprising a supporting part having crossbeams and rollers are arranged above the superstructure and carry a platform which is arranged below the super- structure for carrying casings to extend the projecting superstructure sec- tions. A transport device is movably carried on the auxiliary beam and supports the concreting scaffolds for transport between superstructure sections and from the end of a completed section to a bridge pile for beginning construction or a new section. The supporting part of each of the concreting scaffolds has longitudinal girders arranged adjacent the auxiliary beam and crossbars connected to the girders arranged below the auxiliary beam. A pair of supporting blocks for supporting the auxiliary beam on the next succeeding pile are arranged so as to be alternately retractable to allow the supporting part of the scaffolds to pass the bridge pile.
