The invention relates to a non-foundation steel-structure express overpass. The non-foundation steel-structure express overpass comprises an overpass body, bridge approaches and pier shafts. The bridge approaches are symmetrically arranged on both sides of the overpass body. Both ends of the overpass body are supported by the vertically-arranged pier shafts. The non-foundation steel-structure express overpass is characterized by further comprising connecting sections, one end of every connecting section is matched and fixedly connected with each of the bridge approaches, and the other end of the connecting section is matched and fixedly connected with the overpass body. The overpass body, the bridge approaches, the connecting sections and the pier shafts are respectively of a steel-frame structure. The overpass body is fixedly connected to the upper ends of the pier shafts through bolts. One end of each of the bridge approaches is fixed to the upper ends of the pier shafts through bolts. The lower ends of the pier shafts and the other ends of the bridge approaches are all cradled on the ground through iron plates and connected to the iron plates through bolts. The non-foundation steel-structure express overpass is reasonable in overall structure design, capable of being produced at the factory and directly assembled in site due to the fact that the entire overpass is formed by a steel structure, short in construction period, low in cost and easy to disassemble and maintain.
