Qingdao Haiwan - The Worlds Longest Sea Bridge

China has unveiled the worlds longest sea bridge, which stretches a massive 26.4 miles five miles further than the distance between Dover and Calais and longer than a marathon. The Qingdao Haiwan Bridge was completed on December 27, 2010 and is 26.4 miles long - the equivalent of 174 Tower Bridges, links the main urban area of Qingdao city, East Chinas Shandong province, with Huangdao district, straddling the Jiaozhou Bay sea areas. The road bridge, which took four years and cost a cool 5.5 billion pounds to build, will be open for use in the New Year and is almost three miles longer than the previous record-holder, the Lake Pontchartrain Causeway in Louisiana.
