China has unveiled the world’s longest sea bridge, which stretches a massive 26.4 miles! The road bridge, which took four years and cost a cool £5.5billion 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.



With an overall length of 42.58km, the route between Qingdao and Huangdao will be shortened by 30km, cutting the travel time by about 20 minutes.
