Danbi Bridge is actually the main road in the Temple of Heaven between the Hall of Prayer for Good Harvest and Imperial Vault of Heaven. It is 360 meters long and 29.4 meters wide. A tunnel passes through under the path, so it is called a bridge. The southern end of the road is one meter above the ground and the northern end of it is four meters above the ground. The rise meant to "step upward toward heaven". The central path was reserved for divine gods, the path on the left was reserved for the emperor and the path on the right was used by court officials.
