The first steel box girder of the bridge, weighing 490 tons and covering around 539 square meters, was installed Wednesday, marking a major milestone of the superstructure of the main bridge.

The 24-kilometer Shenzhen-Zhongshan Bridge will connect Shenzhen and Zhongshan, two major cities on the Pearl River Delta in south China's Guangdong Province and shorten the travel time to 30 minutes. Construction of the mega project started in late 2016 and its opening is scheduled for 2024.
