Abstract: The spring ice run on most great Siberian rivers proceeds impetuously and with ice blocking. For the most rapid opening of navigation, it is necessary to ensure the ice movement is free of obstructions through bridge openings, thus eliminating every possibility for ice fields to stop long at piers. A method for estimating minimum dimensions valid for bridge spans is developed in this paper, taking into account the principal factors of phenomena, in particular central surface velocity of the streamflow, the ice floe dimensions and their strength, as well as the size and form of bridge piers. A method developed by the author is used in the USSR for projecting of railway and highway bridges.
