A snowstorm guard fence structure is constructed by anchoring a wall, which overhangs at an upward slope to a road side, to a supporting wall disposed along one side of the road. The constructed structure can be placed on sides of roads, has a space to discard the snow removed from the road, and also is effective for preventing snow accumulation on the road regardless of the degree of wind velocity and the presence of shelter structures. A jet roof is constructed by disposing a plurality of props on a slant and providing a plurality of panels between the props at spaces for jet openings so that jet openings are gradually narrowed toward the road side. The constructed jet roof is effective for preventing snow accumulation on the road regardless of the condition of wind velocity and the presence of shelter structures.
