This Is How The World’s Longest Immersed Tunnel Is Being Built

Tesla is quite famous for constructing tunnels for its hyperloop train, but when they are measured against the world’s longest immersed tunnel, they do not seem anything close to amazing.

The tunnel is called Fehmarnbelt and it connects Rdbyhavn on the island of Lolland to Puttgarden in Germany.

The following video explains how 360,000 tons of steel and 3 million cubic meters of concrete are being transformed into an 18-kilometer-long tunnel.

Once the work on the tunnel is concluded, it will provide the fastest route between Scandinavia and Central Europe.

The tunnel is not at all ordinary. It has become one of Europe’s largest construction sites. The first step in its development is a large-scale harbor. This is where delivery will happen for the huge quantities of sand, cement, steel, and gravel required for the tunnel’s construction.

Behind the harbor, is a tunnel factory with six production halls for casting the tunnel’s 89 elements round the clock. Yes, you read that right. The construction will not stop even for an hour on this site.

What other structures and elements are needed to complete this massive project? What is the science and engineering behind this gigantic tunnel? When is it slated for completion?

This video answers all these questions and more with these detailed illustrations.
