PROBLEM TO BE SOLVED: To provide a bridge structure inexpensively constructible in a short period, and easily constructible at a job site for imparting a gradient and bending in a short span; and a joint member of a pier and a main girder used for this bridge structure. SOLUTION: This bridge structure has the pier and the main girder extended between the adjacent piers; and is constituted so that the joint member for connecting the pier and the main girder is composed of a cylindrical body part fitted around an upper end part of the pier and left-right two support parts extended to the left and right sides of the body part and respectively supporting the left and right main girders connected by sandwiching the pier, and the two support parts have a support surface for supporting the main girders from below, and both end part under surfaces of the main girders are fixed along the support surface.
