Final Draft:

An underwater tunnel is a tunnel, which is partly or wholly constructed under the sea or a river. They are often used where building a bridge or operating a ferry link is unviable, or to provide competition or relief for existing bridges or ferry links.

They are underground artificial passages, which are constructed without disturbing the ground surface. Shedding light on its advantages, tunnels allow rapid and unobstructed transport facilities in big congested cities. Besides, they avoid troubling surface life and traffic during construction. Moreover, underwater tunnels protect the system from destruction due to bombarding during wartime. In the most congested urban areas, underground railways or highways are the best alternative to provide means of transportation.

Coming to the disadvantages of underwater railways is their initial cost of tunnel construction is very high. Moreover, tunnel construction requires skilled labour and technical supervision of high order. Besides, the construction duration of tunnels is longer than bridges or open cuts. Lastly, its construction requires advanced and specialized equipment.

Technological developments have seen the transport industry introduce many new impressive fuel types, touchless technology, robot helpers, and autonomous vehicles. However, the world has pushed advancements one step further with the construction of underwater railways
