An SPC girder bridge structure includes a bridge girder constructed with overhanging bridge body blocks formed of cast-in-place concrete from one section to another between bridge legs by an overhanging construction method. Iron frames and concrete arranged by being connected from one section to another are formed integrally and constructed continuously in a longitudinal direction, first PC steel members are arrange continuously in an upper portion of a main girder except for a central section as a closure portion and second PC steel members are arranged so as to penetrate through a lower portion of the central section and continue to adjacent sections in a curved shape, the first PC steel member on the upper portion of the main girder and the second PC steel members arranged in the lower portion of the main girder of the central section are secured under tension to provide a prestress to the concrete of the main girder.
