Moreover, the only option is to build it in the center of a large city, dig it deep underground, or raise it 50 to 100 to 200 meters above ground, which requires a huge amount of money and takes 10 to 20 years. The invention is intended to solve the above-mentioned difficulties, and as shown in the drawing, several branch roads are directly connected to the main road at the grade intersection point, and furthermore, up and down bridges are directly connected to the branch roads. , which completely completes grade-separated intersections.This does not require the vast land area required in the past, and also makes it possible to build grade-level intersections in the center of large cities and other places, which was previously considered impossible. The aim is to eliminate traffic congestion by popularizing the invented grade-separated bridge.
