FIELD: construction.
SUBSTANCE: invention relates to bridge engineering, namely to construction of foundations of short-term bridges. Method of supporting superstructure delivery to installation site using soft pontoons consists in that delivery of superstructure is carried out by imparting positive buoyancy to it, for this purpose cylindrical soft pontoons are attached uniformly to one side of the superstructure, air is supplied into them, the superstructure is switched to horizontal position and installed by pontoons on water, then it is transported to the place of installation.
EFFECT: invention can be used in reconstruction of railway bridges along old axis and construction of collapsible bridge crossings through water obstacles.
