To provide a hung road of which rigidity in the advancing direction of the road is high, construction is easy, and strength is large.

A tension member 2a of which one end is buried in the natural ground as an anchor, is connected to a pillar standingly provided on the natural ground. A tension member 2b is brought down from the pillar as a hanging material. A road slab 3 made of precast provided with a girder part 5 having a main girder effect on the end part on the valley side and a floor part 6 extending from the girder part 5 to the natural ground side is hung by connecting the tension member 2b to the end part on the overhang side. The girder parts 5 are connected together through cables 10 and the like. A girder member formed into a T-shape by the girder part and a cross girder part is continuously hung, and a floor board can be arranged thereon. Or a road part can be constructed by assembling a mould and concreting hardening material at site. Hereby, the road part is continuously integrated in the advancing direction of the road by the girder parts 5, the strength is improved, and the load is dispersed into a plurality of the tension members. Hung members are not shaked during construction so as to facilitate construction. By concreting at site, it can be constructed even on a place of difficult carry-in.
