FIELD: bridge-building, particularly to erect bridges, overpasses and other transport works.

SUBSTANCE: bridge includes piers, support parts rigidly connected to the piers, span structure, approach slabs and unloading means. Support parts and span structure are rigidly connected one with another. Intermediate panels are mounted within bridge length above bridge aperture, connected one to another and rigidly joined with span structure by one end and with unloading means by another end thereof. The unloading device is formed as retaining wall which serves as a platform for embankment and supported by foundation pad or grillage. Lower edges of retaining walls are joined with foundation pads or with grillage by hinged connection so that retaining wall may rotate relative support axis or by sliding hinged connection so that retaining wall may rotate and move in horizontal direction.
