PROBLEM TO BE SOLVED: To provide a straight road-type suspended floor slab bridge which makes a longitudinal road slope gentle by reducing a sag, and decreases a horizontal force acting on an abutment, and also to provide a construction method the straight road-type suspended floor slab bridge. SOLUTION: The straight road-type suspended floor slab bridge comprises: a primary cable 3 for erecting a suspended floor slab; and a secondary cable 13 for supporting the whole of the bridge. Both the primary cable 3 and the secondary cable 13 are tensioned and anchored together by means of the abutment 2. A cable 9 for directly introducing prestress is arranged in a suspended floor slab body, and tensioned and anchored by an end of the suspended floor slab. The end of the suspended floor slab is supported by an elastic support without being fixed to the abutment 2. COPYRIGHT: (C)2009,JPO&INPIT
