Snow shed

A snow bridge near a ski-resort in Vorarlberg.

Trains passing in an avalanche gallery on the Wengernalpbahn in Switzerland.

A snow shed, snow bridge or avalanche gallery is a type of rigid snow-supporting structure for avalanche control (avalanche defense) or to maintain passage in areas where snow removal becomes almost impossible. They can be made of steel, prestressed concrete frames, or timber. These structures can be fully enclosed, like an artificial tunnel, or consist of lattice-like elements. They are typically of robust construction considering the environments they must survive in.
