PROBLEM TO BE SOLVED: To provide a method for manufacturing a supporting member A for a bridge structure. SOLUTION: When the supporting member A is manufactured, first of all, at least one pile 1 is driven into ground; next, an upper part 11 of the pile 1, which is located above the ground in that case, is covered with a caisson- shaped hollow prefabricated component 2, which has lateral walls 23 and 24 regulating a central hole 20 having an upward opened upper opening 22 and a lower opening 21 into which the upper part 11 is inserted, in such a manner that the component 2 is extended horizontally along a direction crossing a vertical axis of a floor deck B; concrete D is infilled to the height of the upper opening 22 of the central hole 20, in order to bury the upper part 11; and on the concrete D, there is placed at least one distribution plate 5 which has a lower surface 51, abutting on the concrete D, and an upper surface 53 serving as the supporting member A for supporting a part corresponding to the floor deck B after solidification of the concrete D.
