PROBLEM TO BE SOLVED: To provide a method for manufacturing a perfect grade separated crossing, which requires no signal and is used for men and cars, even at a connecting point with a quasi-main road 2 or the like in the intermediate section of a perfect grade separated point in a main road 1 having the grade separated point by a rectilinearly propagated overbridge and an inversion overbridge assisting the overbridge. SOLUTION: In the perfect grade separated crossing method at an intermediate point, the two inversion overbridges 6 are installed at places, where the main road 1 and the quasi-main road 2 or the like are connected in a plane, so that opening sections are faced mutually at both places properly separated on the main road 1. In the method, a bus stop 19a on the main road side is mounted on the inside connected under the state, in which a connecting roadway 20 near to the quasi-main road 2 at the connecting place is opened, while a pedestrian way system by underground sidewalks 22a and 22b passing under the main road 1 and the quasi-main road 2 or the like is secured just under the bus stop 19a, and the efficiency and safety of a man-car traffic are improved.
