A container ship passes under the Lingdingyang Bridge when a steel box girder is lifted to be installed on the bridge on Wednesday. A section of the Shenzhen-Zhongshan Link, the bridge is the world’s longest-span steel box girder suspension bridge in the ocean, with a main span of 1,666 meters. Upon completion next year, the Shenzhen-Zhongshan Link will cut commuting time between the two cities from two hours to 30 minutes.Xinhua
