World`s Longest & Deepest Tunnel – Gotthard Base Tunnel!

The Gotthard Base Tunnel in the heart of the Swiss Alps was opened in 2016. It is a railway tunnel with 151.84 km (94.3 mi) of tunnels, passages, and shafts, and a route length of 57 km. The Gotthard is the longest and deepest rail tunnel in the world which surpasses the Seikan Tunnel in Japan, which previously held the record. The main purpose of the Gotthard Base Tunnel is to increase total transport capacity, especially freight, across the Alps. It was built more particularly to reduce environmental damage caused by numbers of heavy lorries by shifting freight volumes from road to rail. The project is a big step forward; thus, it took around 20 years of constant preparation and construction.
