Abstract

There is disclosed a bridge or like pillar (1) erected in a moving body of water in which the water may periodically flow in strata in one as well as the other of two opposite main flow directions. The pillar is provided with a flow compensation device including a motor-driven stream generator (9) which functions to set part of the water in motion thus compensating for the flow resistance exerted by the pillar in the water body.
