PROBLEM TO BE SOLVED: To provide a construction method for a bridge which has a robust strength and withstands earthquake and the bridge structure thereof. SOLUTION: In the construction method for a bridge, geotextile 2 and sandbags 3 are used according to a procedure of a reinforced soil wall construction method for constructing a reinforcing banking 4. When a support ground 1 is soft, a foundation such as a foundation pile 5 or the like is constructed after a ground sinkage by banking up of the reinforcing banking 4 is settled, and at the same time the geotextile 2 and the sandbags 3 are used for constructing the reinforcing banking 4 at the opposing side. When the support ground 1 is soft, the foundation such as the foundation pile 5 or the like is constructed after the ground sinkage by banking up of the reinforcing banking 4 is setteled, the wall faces 6 of the reinforcing banking 4 facing to each other and a beam part of a bridge girder 7 are integrated, and then reinforced concrete for a rigid frame bridge part 8 is placed.
