【#深圳到中山从2小时缩短至30分钟以内#】今天，深中通道海底隧道贯通，这也标志着深中通道主线正式贯通。深中通道东起广东深圳，西至中山，全长24公里，是集“桥、岛、隧、水下互通”于一体的世界级集群工程。其中，桥梁部分长约17.1公里，海底隧道部分长约6.8公里。The subsea tunnel of the Shenzhen-Zhongshan cross-sea link in south China's Guangdong Province has been completed, marking the full completion of the main line of the mega cross-sea link. The 24-kilometer-long link, connecting the two major cities in the Great Bay Area, consists of bridges with a total length of 17.1 kilometers and a 6.8-kilometer-long tunnel. It will help shorten the commuting time between the two cities from two hours to no more than 30 minutes. For more: http://t.cn/A6Ws7WMZ
