After 17 years of construction, the Gotthard Base Tunnel opens today. This feat of engineering is a 35-mile high-speed rail connection beneath the Swiss Alps and is now the longest transit tunnel in the world. You better believe that Hyperloop engineers are paying attention.
Today, after 20 years of digging by some 2,500 workers, 8 of whom lost their lives, Swiss engineers blasted through the last bit of rock to create the world's longest tunnel. The accomplishment even made macho Swiss miners cry.
