PROBLEM TO BE SOLVED: To provide a floor slab bridge structure extremely effective as a bridge fall preventing countermeasure to a severe earthquake by improving rigid connection strength between a bridge girder and a bridge pier made of concrete, to effectively restrain expansion, flexure and torsion of the bridge girder and to synergistically enhance the strength of connection concrete itself to expansion, torsion, or the like. SOLUTION: The floor slab bridge structure in formed in rigid connection structure wherein slab concrete 3 and the bridge pier 2 made of concrete are connected through connection concrete 11 by placing the slab concrete 3 between the side faces of bridge girders 1 lined up in a bridge width direction, over the longitudinal length of the bridge girders 1, and additionally placing the connection concrete 11 embedding bridge girder portions supported to a bridge seat face 10, on the bridge seat face 10 of the bridge pier 2 made of concrete to support the bridge girders 1.
