China unveiled bridge in the world's longest sea, extending a massive 26.4 miles - five miles longer than the distance between Dover and Calais and more than a marathon.


The Qingdao Haiwan Bridge, completed earlier this week, linking the major cities of Qingdao city, east China's Shandong Province, with Huangdao district, straddling Jiaozhou Bay waters.


Viaduct, which lasted four years and cost a cool £ 5.5billion to build, will be open to the use of the new year and almost three miles longer than the previous record holder, the Lake Pontchartrain Causeway in Louisiana.
