description Donghai Bridge Overview

Donghai Bridge is a long sea crossing that links Shanghai's Pudong area with the Yangshan Deep-Water Port on islands in Hangzhou Bay. Opened in 2005, the roughly 32.5-kilometre structure combines extensive low-level viaduct sections with a cable-stayed navigation span. It was built to provide road access to the offshore container port, supporting freight movement between Yangshan and Shanghai's mainland transport network.

help Donghai Bridge FAQ

What is the purpose of the Donghai Bridge?

The Donghai Bridge connects Shanghai's Pudong area with the Yangshan Deep-Water Port on islands in Hangzhou Bay. It was built to enable cargo transport to and from Yangshan, which was developed as a deep-water facility capable of handling the largest container ships.

How long is the Donghai Bridge?

The Donghai Bridge is roughly 32.5 kilometres long, combining extensive low-level viaduct sections with cable-stayed navigation spans. When it opened in 2005, it was one of the longest sea-crossing bridges ever built.

Can ordinary traffic use the Donghai Bridge, or is it restricted to port vehicles?

The Donghai Bridge carries a multi-lane highway that primarily serves freight traffic going to and from Yangshan Deep-Water Port. General vehicular traffic can use the bridge, but it is functionally a dedicated link to the port rather than a route between population centers.

What engineering challenges did the Donghai Bridge face?

Building a 32.5-kilometre bridge across Hangzhou Bay required overcoming harsh marine conditions including typhoons, strong currents, and soft seabed soil. The structure incorporates a cable-stayed navigation span to allow large vessels to pass beneath it on the way to the port.
