PROBLEM TO BE SOLVED: To provide a bridge capable of being carried out construction work even in a narrow site. SOLUTION: The bridge comprises foundation work carried out in each of spots required for constructing the bridge, an arch member rigidly connecting both ends thereof to both head ends of the foundation work and placed in such a posture that a circular arc can be upward projected, a plurality of hangers suspended from a circular arc part of the arch member and arranging positions of the lower ends in a predetermined position, a hanging floor slab connected to the lower ends of the hangers and extended in parallel with a line connecting the two spots to each other, a rigidly connecting means rigidly connecting one extended end section of the hanging floor slab to one end section of the arch member opposed thereto and a connecting means connecting the other extended end section of the hanging floor slab by relatively allowing the movement only in the extended direction of the hanging floor slab to the other end section of the arch member to which the extended end section is opposed.
