Chinese engineers have embarked on a groundbreaking project to construct a 5-kilometer subsea tunnel for the Shenzhen-Zhongshan Link – a vital transport corridor connecting two major hubs in the Pearl River Delta. The fully immersed underwater structure will use cutting-edge engineering techniques to withstand marine conditions while boosting regional connectivity.
Using the 'immersed tunnel' method, engineers will sink and join 32 massive prefabricated concrete sections weighing 80,000 tons each onto a pre-dug seabed trench. Advanced waterproofing and seismic-resistant designs aim to ensure safety in this earthquake-prone region.
The $6.7 billion mega-project will slash travel time between Shenzhen and Zhongshan from 2 hours to 30 minutes upon its 2024 completion. When operational, it's expected to handle 80,000 vehicles daily, integrating manufacturing and tech hubs in the Greater Bay Area.
'This hybrid bridge-tunnel system represents China's mastery of complex infrastructure challenges,' said lead engineer Wang Liang. 'The technologies developed could redefine sustainable coastal transport globally.'
Environmental monitoring systems have been installed to protect marine ecosystems during construction, aligning with China's green development goals. The project forms part of broader efforts to integrate the GBA's 86 million residents through smart, climate-resilient infrastructure.
