SUBSTANCE: small-sized low automobile-railway crossing consists of a sliding barge bridge and two cable-stayed overpasses, equipped with short retractable supports inserted into guide bushings of cable-stayed overpasses, which in front of ice drift are lifted and free passages under cable-stayed overpasses for passage of ice drift, and at the end of ice drift, they are lowered from cable-stayed overpasses and inserted into connecting sleeves, which at depth of 2.5 m are fixed on piles driven into the bottom of the strait.
