In order to save footprints of elevated road and ramp and improve the overall traffic elevated road feature, a design steel viaduct of looping bi-directional traffic is proposed. The lane next to the side is set to ramp up and down; in order to reduce the interference of double-enter and surface transportation, a dual entrance is proposed to import and export of even and odd numbers distinguish, increase the distance of the entrance to balance traffic load, reducing the 50% blocking probability and ramp construction. Another scenario is that upper and lower layer design loop of one-way traffic, balance the city's traffic load, the combination of multiple loops for one-way traffic dual relationship; perfect double connection traffic and intersections, constitute a complete transportation network. Cities can set the cycle double traffic trunk road network. Steel viaduct for environmentally friendly buildings, can migrate more suitable for future development of old town.
