The completion of the project will bring great relief to lakhs of commuters as it will connect the busy Howrah and Sealdah RAILWAY stations as well as the north-south line of the Kolkata Metro at Esplanade. Another attraction for travellers will be the twin tunnels under the width of the river. Passengers will pass under the water for half a kilometre in less than a minute, giving them a one-of-a-kind experience.
