Yangshan Port (Chinese: 洋山港, p Yángshān Gǎng, Wu Yan-se Kaon), formally the Yangshan Deep-Water Port (洋山深水港, p Yángshān Shēnshuǐ Gǎng, Wu Yan-se Sen-sy Kaon), is an offshore deep-water port for containerization in Hangzhou Bay south of Shanghai, China, built on land reclamation joining the Lesser Yangshan Island with numerous other nearby islands of the northwestern Zhoushan archipelago. It is connected to Shanghai's Pudong New Area on the mainland by the 32.5 km-long (20.2 mi) Donghai Bridge, forming part of the Port of Shanghai, while the other islands of Yangshan archipelago (including the Greater Yangshan Island, where the civilian population of the archipelago live) are administered separately as part of Zhejiang's Shengsi County.
Yangshan Port is part of China's Maritime Silk Road, built to allow the Port of Shanghai to grow despite shallow waters near the shore. Prior to its construction, the Port of Shanghai was predominantly based around the mouth of the Huangpu River, which is too shallow to handle large container ships, forcing the port to often perform mid-stream operations within the Yangtze estuary, which often had to wait for the high tide hours, severely restricting the port's capacity. The construction of Yangshan Port allows berths with depths of up to 15 m (49 ft) to be built, and can handle today's largest container ships. In mid-2011, port officials said the port was on track to move 12.3 million twenty-foot equivalent units (TEUs) during the year, up from 10.1 million TEUs in 2010, overtaking Port of Singapore to become the world's busiest container port. In 2015, the port handled 36.54 million TEUs, and by 2019, its throughput had increased to 43.35 million TEU.
