Jintang Bridge, Steel bridge in Jintang Island, China
Jintang Bridge is a major road bridge in Zhejiang that crosses the sea to link island and mainland areas. The structure uses both prestressed concrete and steel elements across its various spans to achieve this long-distance crossing.
Construction began in April 2006 with an investment of 7.7 billion yuan. The offshore section was joined on 15 July 2008, and the bridge opened to traffic on 25 December 2009. It is the third-longest sea-crossing bridge in China after the Hangzhou Bay and Donghai bridges.
The bridge functions as a connection point between mainland China and the Zhoushan Archipelago, influencing the movement of goods and people across the region.
The bridge carries vehicle traffic between the two areas and is part of the larger highway system. Be aware it is a toll road that undergoes regular maintenance.
The main navigation span is a cable-stayed section with a 620-metre main span between two towers, carrying cables in two planes. It is rated for vessels of 50,000 tonnes and is described as the longest cable-stayed span built in open sea. The bridge deck is 26 metres wide and carries four lanes in two directions.
