Two bridge parts of an expressway over a railway line were made to rotate for 78 degrees in south China's Guangdong Province Friday morning. Each of the bridge parts is 150m long, 31.7m wide and weighs 13,500 tons. The two bridge parts form a section of the Shantou-Kunming expressway, which links the Shantou City in Guangdong Province to Yunnan Province's capital Kunming.
