Introduction to Haitian Yizhou Observation Deck: There is an offshore platform built on the sea 14 kilometers away from the south bank of the bridge. It served as the midpoint between the north and south banks during the construction of the bridge to facilitate the transportation of building materials. After the construction is completed, this platform will become a bridge transfer station integrating rescue and sightseeing. There is also a lookout tower on the platform that is as big as two football fields. Standing on the tower, you can not only enjoy the sea scenery, but also overlook the entire bridge building. It is an indispensable part of the Hangzhou Bay Bridge.
