In March, 2024 PM Narendra Modi inaugurated India’s first underwater metro section in Kolkata.
The metro tunnel has been built under Kolkata's Hooghly River that will connect Howrah Maidan to Esplanade.

The Howrah Maidan-Esplanade section passes under the river Hooghly, on the east and west banks of which are situated Kolkata and Howrah City.

The Metro will take to a 520-metre stretch under the river Hooghly in 45 seconds.
The 4.8 km stretch between Howrah Maidan and Esplanade is the 2^nd section of the East-West Metro corridor between Howrah Maidan and the IT hub Salt Lake Sector V.
Out of the total 16.6 km length of the East-West Metro, the underground corridor constitutes 10.8 km between Howrah Maidan and Phoolbagan, with the tunnel under the Hooghly River while the rest of the stretch is an elevated corridor.
Positioned 26 meters below the river’s surface, the tunnel allows trains to operate 16 meters beneath the riverbed.
