While passing through the elevated corridor, the Kolkata Port which is the only riverine Major Port in India is fully visible. Situated 232 kms up-stream from the Sandheads with arguably the longest navigational channel amongst Major Ports of India, its navigational channel is one of the longest in the world. The Port which was once considered the most important port in the country still remains the premier port which has been rightly called the gateway to Eastern India and is the guiding factor to trade and commerce of vast hinterland comprising the entire Eastern India including Bihar and Eastern Uttar Pradesh and the two land-locked Himalayan Kingdoms of Nepal and Bhutan. Apart from eminent Cargos ships, well-known Passenger Ships like MV Akbar, MV Nicobar, MV Harshavardhan regularly pay visit to this port.
