How Denmark Is Building an 18 KM Underwater Tunnel to Germany

🚇 Denmark is building the world's longest immersed tunnel: about 18 km under the Baltic Sea between Denmark and Germany, made from 89 giant concrete elements built on land and sunk into a trench in the seabed. Each standard element is 217 meters long and weighs around 73,000 tonnes, more than the Titanic.
