This is the lowest point recorded in underwater shield tunneling to date. The machine is being used in the development of the Haimen-Taicang highway in east China's Jiangsu Province. Around a third of the 39-kilometer-long project runs under the Yangtze River. It's the world's longest underwater highway tunneling project. #FrontlineStory 📺 Subscribe to our YouTube channel and stay updated with our latest analysis and interviews:👇 https://www.youtube.com/channel/UCgrNz-aDmcr2uuto8_DL2jg 👈 Download our APP on Apple Store (iOS): https://itunes.apple.com/us/app/cctvnews-app/id922456579?l=zh&ls=1&mt=8 Download our APP on Google Play (Android): https://play.google.com/store/apps/details?id=com.imib.cctv For more: https://www.cgtn.com/video Most watched videos: Impossible Challenge: 30 seconds to count banknotes BLINDFOLDED https://www.youtube.com/watch?v=ZmP_Ybj-jws Impossible Challenge: Gymnastics Boy Arat Hosseini from Iran! https://www.youtube.com/watch?v=8sxX--U4c8w Impossible Challenge: How to calm babies in 5 seconds? https://www.youtube.com/watch?v=kR3q9sXM7WA Mon, 04 May 2026 12:13:43 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://tankie.tube https://tankie.tube/lazy-static/avatars/3ba3ff73-a8b6-49c9-add8-9653ef090c7f.webp https://tankie.tube/videos/watch/437005a8-f40c-4567-9683-798584b4639b All rights reserved, unless otherwise specified in the terms specified at https://tankie.tube/about and potential licenses granted by each content's rightholder.
