Jiaxing-Shaoxing Sea Bridge, Cable-stayed bridge in Zhejiang, China

The Jiaxing-Shaoxing Sea Bridge is a multi-pylon cable-stayed bridge across the Qiantang River estuary, running 10.14 km from Shaoxing's north-east bank to landfall south of Jiaxing. Its main span is 2,680 m long and 55.6 m wide, with six pylons carrying two steel box-girder carriageways tied together and eight traffic lanes.

Construction began in December 2008, and the toll bridge opened on 20 July 2013. It was the second sea-crossing bridge in the greater Hangzhou Bay area, built about 50 km west of the Hangzhou Bay Bridge, which had opened in May 2008. The bridge received the IRF Award in 2016 and the FIDIC Award of Special Merit for 2017.

The bridge stands as a representation of Chinese engineering capabilities, connecting the cities of Jiaxing and Shaoxing while facilitating regional development.

The bridge is open to vehicle traffic and requires a toll fee for crossing. Drivers should expect an organized traffic system and should follow all safety regulations.

The structure uses a special design with single piers that block water flow in the bay less than traditional bridge constructions. This innovative system helps manage the region's strong tidal currents while maintaining stability.
