PROBLEM TO BE SOLVED: To provide a bridge with a damping function, which can exert the excellent damping function by employing restrictive damping materials and executing simple construction. SOLUTION: The bridge is composed of a main girder structure and a concrete floor slab structure. The main girder structure is constructed by sequentially arranging main girder unit structures each having at least a pair of steel main girder unit bodies opposed to each other and in parallel with each other, and a transverse girder connecting between the main girder unit bodies, in a longitudinal direction via main girder expansion gaps. The concrete floor slab structure is constructed by sequentially arranging concrete floor slab unit bodies which are formed corresponding to the main girder unit structures, respectively, and connected to upper surfaces of the main girder unit structures, respectively, via floor slab expansion gaps. Then, rigid members are stuck to a single side surface or both side surfaces of the main girder unit body so as to cover a predetermined area of the single side surface or both the side surfaces of the main girder unit body, by an elastic adhesive, and thus the damping function is exerted.
