PROBLEM TO BE SOLVED: To provide a waterproofing method in a bridge expansion / contraction part which can be easily and quickly waterproofed without requiring skill and can be executed at a low cost regardless of the size of the bridge. SOLUTION: The bridge girder 2 is provided at the boundary between the bridge girders 2 and 2 constituting the bridge or the boundary between the bridge girder 2 and the abutment parapet that supports one end of the bridge girder 2 at both ends of the bridge, and expands or contracts the bridge girder 2 due to changes in temperature. A waterproof construction method for preventing water from entering the bridge expansion / contraction part 3 for absorption, which has heat resistance to withstand pavement heat during road surface paving and pressure resistance that does not deform due to vehicles traveling on the road surface 4 or the like. This is a method in which the covering member 12 is prepared, the covering member 12 is covered so as to cover the bridge expansion / contraction portion 3, and the covering member 12 is fixed to at least one of the adjacent bridge girders 2, 2.
