The East-West Metro Corridor project which is India's first underwater metro service is expected to be completed by December 2023.
The underwater metro which will run through the Hooghly River will connect the cities of Kolkata and Howrah.
Two German-made tunnel boring machines (TBMs), named Prerna and Rachna, were deployed for the process.
Of the total 16.55 km length of the project, 9.30 km length between Sector V and Sealdah is operational. The remaining 7.25 km length is likely to be operational by December 2023.
The first metro rail system in India was also started in Kolkata from Dum Dum to Tollygunge in 1984.
The first metro rail system in the world was started in London on 10 January 1863.
