ensured by stiffening diaphragms and crossbeams placed inside the girders with 4.0 m
pitch, which corresponds to the pitch of the diaphragms. The orthotropic deck of the
carriageway consists of steel deck plate (12 mm thick sheet), longitudinal stiffeners
of trapezoidal closed cross-section with a pitch of 600 mm and cross-beams with a
pitch of 4000 mm.
As for the design solution of proposed superstructure unit, it consists of seven
elements of the same type, suitable in size for railway transportation: two units
of box girders and five plates of the orthotropic deck. In this case, the plates are
only two makes—the intermediate plate and the end plate. The main girders of the
