The Most Impressive Tunnel in the World: 57 Kilometers beneath the Alps that Revolutionized Engineering History!
It is measured in milestones: colossal bridges, skyscrapers that touch the sky, and tunnels that cut through impossible mountains. Among them all, one takes the crown. The Gotthard Base Tunnel, opened in 2016 in Switzerland, is not only the longest in the world at 57.1 kilometers, it is also the deepest, drilling up to 2,300 meters through alpine rock.
A Giant Underground
The Gotthard Base Tunnel runs through the heart of the Alps and connects the north and south of Europe. Building it took 17 years of continuous work and an army of engineers, geologists, and workers who faced extreme conditions of pressure and temperature. The opening in 2016 marked a before and after in global rail transport.
Traveling at 250 km/h in the mountain’s depths
Inside this underground colossus, trains reach speeds of 250 km/h, reducing the journey between Zurich and Milan by over an hour. The tunnel is not just a shortcut: it is a strategic corridor that moves goods and people quickly.
Technology to the Limit
The Gotthard Base Tunnel is a permanent innovation laboratory. Its ventilation systems, fire sensors, and constant monitoring make it an underground fortress. Everything is designed to maintain safety in a space where depth reaches extreme levels and any failure could be fatal.
