PURPOSE: A precast prestressed concrete girder bridge and a construction method thereof are provided to conveniently and completely enable an upper structure of a bridge to be precast in order to obtain high quality and longevity and to improve workability and economic efficiency. CONSTITUTION: A precast prestressed concrete girder bridge comprises a plurality of outer girders (40), a plurality of inner girders (41), and a precast slab (70). The outer girders are individually arranged on the outermost side of a bridge width in a transverse direction and comprise a stairs-shaped short protrusion unit in an upper flange on one side. The inner girder is arranged side by side by including a gap between outer girders and individually comprises the stairs-shaped short protrusion on both sides of the upper flange in the transverse direction. The precast slab is individually arranged between the outer girder and the inner girder and between the inner girders, and the side surface of the precast slab is engaged with the short protrusion unit. |
