CHINA-HENAN-SWIVEL BRIDGE-ROTATION (CN)

Staff members from Zhengzhou Engineering Co., Ltd of China Railway Seventh Group work at the rotation construction site of a swivel bridge in Zhengzhou, capital of central China's Henan Province, Aug. 29, 2019. The 317-meter-long and 38.7-meter-wide Dahe Road bridge, which lies across three railway lines, was successfully rotated to its targeted position on Thursday. The weight of the swivel bridge, which reaches 60,000 tonnes, refreshed the world record of its kind. China has adopted the swivel construction method in building many bridges. The method helps overcome the constraints of environment and traffic, while shortening the construction period. (Xinhua/Li An)
