BEIJING: China has opened the world's longest cross-sea bridge. The Jiaozhou Bay bridge is 26 miles (42 kilometers) long and links China's eastern port city of Qingdao to an offshore island, Huangdao. State-run CCTV says the 110-foot (35-meter)-wide bridge is the longest of its kind and cost more than 10 billion yuan ($1.5 billion). It has taken four years to build the bridge, which is supported by more than 5,000 pillars. According to Guinness World Records, the previous record holder for a bridge over water is the Lake Pontchartrain Causeway in Louisiana. The Chinese bridge is more than 2.5 miles (4 kilometers) longer.
