The Donghai Bridge China

The Donghai Bridge

Donghai Bridge was the longest cross-sea bridge in the world until Hangzhou Bay Bridge opened on May 1^st 2008. It was completed on December 10, 2005. It has a total length of 32.5 kilometres (20.2 miles) and connects mainland Shanghai and the offshore Yangshan deep-water port in China.The bridge is under construction. It is one of the most interesting projects I know besides the World Expo and the Hangzhou Bay bridge. The 32 km long bridge will extend to the island at the heart of the Hangzhou bay and it is the first bridge that will enable us to drive onto an island in Shanghai. 


The A2 expressway connects A20 and the bridge.And The bridge linking mainland Shanghai with Yangshan port opens this month in Donghai just outside Shanghai. Yangshang is expected to become the biggest deep-water in northeast Asia when completed in 2010. Construction of the 's' shape bridge took just two and a half years and cost 10 billion yuan ($1.2 bn) which included 30% overruns on the original budget due to piling difficulties.To provide a safer driving route in the typhoons and high waves known to hit the region, Donghai Bridge is designed in an S-shape. The structure, reported by Shanghai Daily to have cost $1.2 billion, will hold its title of China's -- and one of the world's -- longest over-sea bridge for only a couple of years, though. In 2008, the nearby 22-mile Hangzhou Bay Transoceanic Bridge, which also begins (or ends, depending on your journey) in Shanghai, will earn the superlative.
