Donghai Bridge (simplified Chinese: 东海大桥; traditional Chinese: 東海大橋; pinyin: Dōnghǎi Dàqiáo; literally "Big East Sea Bridge") is one of the longest cross-sea bridges in the world. It was completed on December 10, 2005. It has a total length of 32.5 kilometres (20.2 mi) and connects mainland Shanghai and the offshore Yangshan deep-water port in China. Most of the bridge is a low-level viaduct. There are also cable-stayed sections to allow for the passage of large ships, largest with span of 420 m. Donghai Bridge is part of the S2 Hulu Expressway.
The bridge has a long and narrow speedway and does not allow vehicles that do not meet the weight requirements.
