FIELD: roads.
SUBSTANCE: invention relates to anti-icing methods, specifically to methods of controlling ice formation in fresh small streams at intersection of their transport structures, for example road or railways. Method of for ice-free water passage in under-bridge beds of small bridges includes insulation of bed. In hole of the bridge is deepened bed and filling draining heat-insulating material in form of foamed glass to ensure preservation of positive temperatures at bottom of channel for free passage of water.
EFFECT: technical result consists in improvement of reliability of transport facilities due to elimination of ice-formation in under-bridge streams.
