Hangzhou Bay Bridge is an S-shaped cable-stayed bridge. Starting in Jiaxing to the north, the bridge ends at Ningbo's Cixi County in the south. It shortens the ground transportation distance from Ningbo to Shanghai by 120 km. Construction was started in 2003 and completed in 2007. The bridge was open to the public on May 1, 2008. It helps relieve the traffic congestion for Shanghai-Hangzhou-Ningbo Expressway significantly.
The bridge consists of nine sections. It is 33 meters wide with six lanes, three in each direction. The total length is 36 km which makes it the longest sea-crossing bridge in the world and is expected to last at least 100 years.
There are two navigable bridges. The north navigable bridge is a cable-stayed bridge with twin diamond-shaped towers, double cable and steel box-girders. The main span of the north approach is 448 meters. The south navigable bridge is a cable-stayed bridge with an A-shaped single tower, double-cable and steel box-girders. The main span is 318 meters.
Situated 1.4 km away from the south shore is a 12,000 square meters offshore platform used for rescue services. It is also a tourist leisure area.

杭州灣跨海大橋是一座橫跨中國杭州灣海域的跨海大橋，它北起浙江省嘉興市海鹽鄭家埭，南至寧波市慈溪水路灣。橋於2003年施工，2007年竣工，2008年5月1日正式啟用。通車後寧波至上海陸路距離縮短120餘公里，大大減輕滬杭甬高速公路交通堵塞。
橋分九段，橋寬33公尺，橋面為雙向六車道。全長36公里，是世界上最長的跨海大橋。設計使用壽命100年以上。
大橋設兩個通航孔。北通航孔橋為主跨448公尺鑽石型的雙塔雙索面鋼箱梁斜拉橋。南通航孔橋為A字型單塔單索面鋼箱梁斜拉橋，主跨318公尺。
在離南岸約14公里處，設計有一個面積達1.2萬平方公尺的交通服務救援海上平台，同時也是一個旅遊休閒觀光平台。
