China just dropped a jaw-dropping engineering flex with its largest-ever self-developed tunnel-boring machine (TBM)! Dubbed a “mechanical dragon,” this 145-meter-long, 5,000-tonne beast can carve tunnels as wide as a five-story building is tall. Talk about next-level infrastructure!
Built in Hunan Province by tech giants CRCHI and China Railway 14th Bureau Group, the TBM is set to drill a critical tunnel beneath the Yangtze River, linking Nantong and Taicang in Jiangsu Province. Once complete, this underwater highway will turbocharge regional connectivity and economic growth in the Yangtze River Delta.
“This marks China’s mastery of 16-meter-class tunneling tech,” said CRCHI chairman Zhao Hui. Forget slow boats or winding roads—this project could slash travel times and boost trade networks like never before.
