The Jiashao Bridge is a cross-sea bridge. The Jiashao Bridge is 10.137 kilometers long, starting from Guzhu Hub in the south, crossing Hangzhou Bay, and ending at Nanhu Hub in the north. The bridge deck is a two-way eight-lane expressway with a design speed of 100 kilometers per hour. The Jiashao Bridge is a river crossing channel connecting Haining City, Jiaxing City and Shangyu District, Shaoxing City in Zhejiang Province, China. It is located in the Hangzhou Bay waters of Zhejiang Province, China, and is a component of the Changtai Expressway.

However, please note that there is no sea under the Jiashao Bridge, but the famous Qiantang River. The Jiashao Bridge is the first world-class bridge built by humans at the estuary of the Qiantang River, one of the three largest tidal estuaries in the world (Qiantang River in China, Amazon River in Brazil, and Ganges River in India).
