🦃th是什么的缩写🦄     

th是什么的缩写一座集桥、岛、隧、水下互通于一体的中国跨海集群工程创下了10项世界纪录，它就是深中通道。经过七年的建设，深中通道于2024年6月30日正式通车，它将深圳至中山的车程从2小时左右缩短至30分钟以内，进一步连通大湾区，为当地发展带来新机遇！

After seven years of construction, the Shenzhong Link opened to traffic on June 30. This mega sea-crossing project, integrating bridges, islands, and underwater tunnels, has set 10 world records -- five for the Shenzhong Bridge in the west and five for the Shenzhong Tunnel in the east.

This project will slash travel time from Shenzhen to Zhongshan from around 2 hours to less than 30 minutes, further connecting the Greater Bay Area and bringing new development opportunities!
