Biggest Underwater Tunnel

At 65-miles, the proposed tunnel would be twice as long as the Chunnel between France and England, and could connect New York City with London. It’s been hailed as the greatest railway project of all time.

Experts forecast that the completed service could carry 3% of the world’s freight and earn £7billion GBP per year. Engineers have said the project could reach break-even in seven years.

Proposed tidal energy plants could provide 10 gigawatts of energy and a string of wind power fields could churn a constant supply of clean energy.

The tunnel alone would take fifteen years to complete — and an energy and railway network would take many more — but the project would significantly change the shipping and energy industry.
