This is Guiyang Qianchun interchange, the maximum vertical drop of the highway interchange is 55 meters, 5 layers of interchange, a total of 11 ramps, 8 entrances and exits. The wrong exit is a half-day tour of Guiyang.#VenmoSpringBreak #novelty #macysownyourstyle #exploration #trip #scenery #miracle #China #bridge
