The underwater metro in Kolkata is almost complete and is expected to start soon. It's a project that will not only make commuting much faster for the residents of Kolkata but will also put the city on the global map once again because it's the first underwater metro project in India.
Known as the East-West Metro project, the underwater metro will pass through under the Hoogly river, connecting Howrah and Sealdah Railway Stations – two of the busiest railway stations in the world. The 520 metre twin tunnel is built 30 metres below the riverbed, and it's being estimated that the passengers commuting from Howrah to Mahakaran metro station are going to travel in about one minute as the train will pass the tunnel at a speed of 80km/hour.
This project is sure to attract about one million (10 lakh) passengers who will use the metro line every day by the year 2035. The tunnel that has been constructed using the world's finest technology will be ready by 2021, though it's been in the news for years now since the project's foundation stone was laid in 2009.
