Kolkata, India – March 31, 2026 – In a significant milestone for urban infrastructure development, India has inaugurated its first underwater metro tunnel. The project, a part of the Kolkata Metro's East-West Corridor, plunges beneath the Hooghly River, connecting the twin cities of Kolkata and Howrah. This engineering marvel is expected to revolutionize public transportation in the region, significantly reducing travel time between the two cities and easing congestion on existing road networks. The tunnel, constructed using advanced Tunnel Boring Machines (TBMs), is designed to withstand immense hydrostatic pressure and seismic activity, ensuring the safety and reliability of the metro service. The construction involved intricate excavation and sealing techniques to create a watertight environment. The East-West Metro corridor aims to connect Salt Lake Sector V, the IT hub of Kolkata, with Howrah, a major railway terminus. The underwater section spans approximately 500 meters, with the entire tunnel system extending much further. This project is a testament to India's growing capabilities in complex engineering and infrastructure development. It is anticipated to boost economic activity by improving connectivity and accessibility for commuters and businesses. The inauguration ceremony was attended by prominent dignitaries, highlighting the strategic importance of this project for national development.
