Bering Strait Tunnel by the mega Engineering

The Bering Strait tunnel has become the most expensive and ambiguous tunneling project. To build it needed thousands of miles railroad tracks and 2 massive boring machines. "Bering Strait Tunnel" would be the longest in the world than any other subway and it connects the countries Russia and Alaska that would have a freight route, high-speed rail line and a crucial oil pipeline.

Workers would lay almost 4,000 miles of railway to connect the nearest rail heads to the tunnel. On the other hand massive Tunnel Boring Machines would be started at 64 miles apart on both sides of the strait and they will meet in the middle. While building this tunnel there will be very high risk of mountains, earthquakes, permafrost regions and summer swamps.

This Tunnel can be a deadly project as it has subzero temperature. It is an underwater tunnel for trains with a gas pipeline which could transform the future of fuel and revolutionize global trade. The question arises that can engineers make the dream in the reality or not.
