Aerial photo taken on Sept. 21, 2019 shows a steel girder being lifted by a crane at the construction site of the Pingtan Strait Road-rail Bridge in southeast China's Fujian Province. China on Wednesday completed the main structure of the world's longest cross-sea road-rail bridge in Fujian. The last steel girder, weighing 473 tonnes, was bolted on the Pingtan Strait Road-rail Bridge, another mega project in China, on Wednesday morning. With a staggering span of 16.34 km, the bridge connects Pingtan Island and four nearby islets to the mainland of Fujian Province. (Xinhua/Lin Shanchuan)
