Gothard Base Tunnel

Billed as Switzerland’s “Construction of the Century,” the Gothard Base Tunnel, the longest and deepest rail tunnel in the world, inaugurated on June 1 amid colorful events, fireworks, and abundance of yodeling and alphorns.

The project lasted 17 years, involving about 2,600 workers, costing over $12 billons, and the tunnel opened up with nine losing their lives in the construction of the tunnel.

Instead of making a long journey around the Alps of the Swiss, travelers can now fly straight underground on lighting fast trains.

The Gothard Base Tunnel consists of two separate single-track tunnels running through the Dutch port of Rotterdam in the north to the Italian port of Genoa on the Mediterranean.

The tunnel is 57 kilometers long 35 miles that bypasses many famous mountainsThe Gothard Base Tunnel reaches a mere depth of a mile and a half (2,300 meters or 7,545 feet) beneath the surface of the earth will cut down half of the travel time between Zurich, Switzerland and Milan, Italy.

To cool down the air inside the tunnel to 28-degrees, a lot of electricity was used to bring fresh air into the tunnel.

The project consists of two separate single-track tunnels running through the Dutch port of RotterdaThe main purpose of the Gotthard Base Tunnel is to increase total transport capacity across the Alps, especially for freight, notably on the Rotterdam–Basel–Genoa corridor, and more particularly to shift freight volumes from road to rail to reduce fatal crashes and environmental damage caused by ever-increasing numbers of heavy trucks.
