Important Days & Events Current Affairs

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. The successful completion of this underwater tunnel is expected to pave the way for similar ambitious projects in other water-logged or geographically challenging areas across the country. The operationalization of this segment is projected to carry thousands of passengers daily, integrating the two sides of the river more seamlessly than ever before.

World Tuberculosis Day is observed annually on March 24th to raise public awareness about the devastating health, social, and economic consequences of tuberculosis (TB) and to intensify efforts to end the global TB epidemic. The theme for World Tuberculosis Day 2026 is 'Uniting to End TB', emphasizing the critical need for global collaboration and concerted action from governments, healthcare providers, civil society, and affected communities to achieve the ambitious targets set for TB eradication. This year's observance highlights the progress made in TB prevention and treatment, while also acknowledging the persistent challenges, including drug-resistant TB, the impact of co-infections like HIV, and the need for equitable access to diagnostics and care, especially in low-resource settings.
