A multifunctional and multi-story crossroad for intensive land use relates to urban road construction engineering and solves technical problems of urban traffic jams through space division and streamlined design, without occupying the land outside the road. It achieves: operating smoothly without red lights, large vehicle-free intersection space on the ground, large parking areas, long 'side of the road' border between the parking area and roads, bicycle exclusive system. Technical elements include: learning from building design, multi-story crossroad, 'Turning Right and Looping Back technique', &#x201c;exclusive bikeway interlayer&#x201d;, &#x201c;adding a lane&#x201d;, and &#x201c;large steps above ramp of a tunnel.&#x201d; It is a combination of a smoothly flowing crossroad technique, viaduct and the tunnel. The main purposes are: for new construction and renovation of crossroad in congested cities, and development of city fast lanes, elevated roads and tunnels.
