The 16.6 km long Kolkata East-West Metro line is estimated to carry approximately 10 lakh people every day by 2035. The underwater travel will take place 30 metres beneath river Hooghly, a branch of the river Ganga. The journey will commence through 520 metres long twin tunnels, where one tunnel would be East-bound and the other West-bound.
The 16.6 km long Kolkata Metro East-west corridor will comprise of a 5.8 km long elevated section, while 10.8 km of the stretch will be the underground corridor.
The elevated stations of Kolkata Metro East-west corridor are mapped around Sector-V station, Karunamoyee station, Central Park Station, City Centre Station, Bengal Chemical Station, Saltlake Stadium Station. The underground corridor has stations at Phoolbagan station, Sealdah station, Esplanade, Mahakaran station, Howrah station, and Howrah Maidan.
This project is expected to cut down on the travel cost as well as the time of travel across the most populous of areas in Kolkata. The underwater tunnel will act as the prime attraction though, providing a unique travelling experience which will also be the first of its kind in India.
