What is the deepest driving tunnel in the world?

The deepest driving tunnel in the world is the Gotthard Base Tunnel, located in Switzerland. This remarkable tunnel was officially opened in 2016 and runs under the Swiss Alps, connecting the towns of Erstfeld and Bodio. The Gotthard Base Tunnel stretches an impressive 57 kilometers (35 miles) in length and reaches a depth of 2,300 meters (7,546 feet) below the mountain’s surface. It is a pivotal part of the European transportation network, linking northern and southern Europe.

This groundbreaking engineering feat took nearly two decades and billions of dollars to complete. The tunnel was constructed with state-of-the-art technology, including complex drilling machines and innovative safety measures. It was designed to accommodate high-speed trains, notably reducing journey times between Zurich and Milan. The Gotthard Base Tunnel is not only the deepest in the world but also the longest railway tunnel globally, enhancing connectivity and promoting economic growth in the region.
