Towers complete on world's longest high-speed rail bridge over the sea #coolchina

All seven main towers of the Hangzhou Bay Cross-Sea Railway Bridge were topped out in Jiaxing, east China's Zhejiang, on September 3, marking a major milestone for the world's longest high-speed rail #bridge over the sea. The bridge uses factory prefabrication and integrated assembly to withstand challenging tidal and high-humidity conditions. With #construction now moving to the upper structure, the 350 km/h high-speed rail line will transform travel across the #Yangtze River Delta. 📺 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://news.cgtn.com/news/2026-09-04/Towers-complete-on-world-s-longest-high-speed-rail-bridge-over-the-sea-1QatFv36cxO/p.html 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
