<P>PROBLEM TO BE SOLVED: To improve train traveling property in the event of an earthquake by preventing irregular displacement within a horizontal plane such as positional slippage or angular slippage. Ž<P>SOLUTION: In the reinforcement structure 1 of viaduct connection, an adjustment girder 3 is laid between a rigid frame viaduct 2 and a rigid frame viaduct 5 disposed along a bridge axial direction, and an end portion 2a of the viaduct 2 opposed to the adjustment girder 3 and an end portion 3a of the adjustment girder 3 opposed to the viaduct 2, or opposed end portions 2a and 3a are mutually connected by a reinforcement member 4. The reinforcement member 4 is disposed on the track floor upper surface so as to straddle the opposed end portions 2a and 3a. Similarly, an end portion 5b of the viaduct 5 opposed to the adjustment girder 3 and an end portion 3b of the adjustment girder 3 opposed to the viaduct 5, or the opposed end portions 5b and 3b are mutually connected by a reinforcement member 4, and this reinforcement member 4 is disposed on the track floor upper surface so as to straddle the opposed end portions 5b and 3b.
