Summary:PROBLEM TO BE SOLVED: To provide a method for joining a viaduct having a high waterproof performance and can flexibly correspond to an enlargement and reduction of a space part in accordance with expansion and contraction of the viaduct by temperature difference and a waterproofing layer is not easily deteriorated by protecting the waterproofing layer from damage factor. SOLUTION: A buffer member 25 is arranged inside of a space part 3 formed between a bridge 1 and 1' adjacent to each other, a waterproofing layer 36 having flexibility by spraying elastomer is formed so as to cover a whole of the top face of the buffer member 25 and at least one part of the top face of the bridge adjacent along the space part, and a protective layer 40 is formed so as to cover the waterproofing layer 36 and at least one part of the top face of the bridge 1 and 1' adjacent along both sides of the waterproofing layer 36.
