That is a bridge too far: World's longest sea bridge opens to traffic in China... but it will only hold the title for five years | Mail Online: "The engineering feat will only hold the record as the longest sea bridge for a few years - it will be beaten by another Chinese bridge in the next decade.
Last December officials announced workers had begun constructing a bridge to link southern Guangdong province with Hong Kong and Macau. Set to be completed in 2016, officials said the £6.5billion bridge will span nearly 30 miles. It will be designed to cope with earthquakes up to magnitude 8.0, strong typhoons and the impact of a 300,000 tonne vessel.
But both structures will still be dwarfed by the longest bridge in the world, also in China.
The Danyang-Kunshan Grand Bridge is an astonishing 102 miles in length."
