PROBLEM TO BE SOLVED: To provide a rational construction method for a truss bridge, reducing the term of construction for a concrete truss bridge. SOLUTION: A precast concrete segment 11 of an upper chord material provided with a through hole 12 for passing a single item diagonal member 31, a precast concrete segment 21 of a lower chord material provided with a receiving recessed part 22 where the end part of the single item diagonal member 31 is seated, and the single item diagonal member 31 are respectively individually manufactured in advance, and the precast concrete segment 11 of the upper chord member, and the precast concrete segment 21 of the lower chord member are connected to the adjacent already constructed upper and lower chord members 10, 20, respectively by PC stretch material. The single item diagonal member 31 is a steel product, and passed from above through the through hole 12 of the precast concrete segment 11 of the upper chord member, and the lower end is seated in the receiving recessed part 22 of the precast concrete segment 21 of the lower chord member. The precast concrete segment 11 of the upper chord member, the precast concrete segment 21 of the lower chord member and the single item diagonal member 31 are connected to one another.
