Excavation of India’s First Undersea Tunnel Completed for Mumbai-Thane Section of Bullet Train Project
The National High Speed Rail Corporation Ltd. (NHSRCL) has successfully completed the excavation of a 4.8 km undersea tunnel beneath the Mumbai-Thane creek. This is a critical milestone for the Mumbai-Ahmedabad high-speed rail corridor, marking India's first undersea tunnel. Additionally, Japan has agreed to provide the latest E10 Shinkansen trains for the project. The tunnel was constructed using simultaneous excavation from both sides through challenging underwater terrain. The first section of the bullet train project is expected to be operational by 2027, with the full stretch to Mumbai slated for 2029.
