The correct option is C. India’s first underwater metro rail tunnel has been constructed under the Hooghly River.
– The underwater metro tunnel is part of the Kolkata Metro’s East-West Corridor project.
– The tunnel passes beneath the Hooghly River, connecting the city of Kolkata with Howrah.
– This project represents a significant engineering achievement in India’s infrastructure development.
The Kolkata Metro, operational since 1984, was the first metro system in India. The East-West Corridor project, including the underwater section, aims to further expand and modernize the network, providing faster connectivity between key areas. The underwater section under the Hooghly is a particularly complex part of the construction.
