The invention relates to an overpass concrete outside-hanged cantilever type flower bed, simultaneously relates to a construction method thereof, which and belongs to the technical field of building construction. The flower bed comprises a reinforced concrete flange extending upwards from the edge of the horizontal bridge width direction. The bottom of the reinforced concrete flange further extends outwards and upwards to form an arc-shaped outer bed edge. A bed cavity with big end up is arranged between the outer bed edge and the flange, the section of the bed cavity is similar to a trapezoidal shape, and a broken stone cushion layer is overlaid at the bottom of the bed cavity. A horizontal water pipe extending along the length direction of the bed cavity is supported on the upper surface of the broken stone cushion layer, and penetrating water drainage pipes penetrating from the upper surface of the broken stone cushion layer of the bed cavity to a bridge floor water drainage pipe are distributed on the con
