Switzerland has completed the construction on the world’s longest tunnel. This is the longest and deepest train tunnel in the world.
The Gotthard Base Tunnel is a stunning feat of engineering.Workers have bored nearly 100 miles of tunnels into the Alpine mountains, to create a route between the two Swiss cities of Erstfield and Bodio.
The Swiss Alps are an unforgiving landscape of rugged, rocky peaks and lush, green valleys. Connecting communities that would be otherwise isolated by the vast mountain range — including cultural and economic hubs such as Zurich, Milan, and Turin — is no easy task.
Tunneling and track-laying for the 35-mile NEAT Gotthard Base Tunnel has been completed, making it officially the longest tunnel in the world, surpassing Japan’s 14-1/2-mile Seikan Tunnel.
Swiss authorities held a media day inside the tunnel on Monday to announce that most of the technical work for the tunnel had been completed, the Swiss newspaper TDG reports. Testing will begin October 1 in anticipation of the first passenger and freight trains in June 2016.
Most of this area — inhabited by approximately 111 million people — is relatively flat, except for Switzerland’s notorious Alps. The Gotthard Pass has proven itself a vital link between Switzerland and northern Italy for hundreds of years.
This new tunnel has been financed entirely by Switzerland, at a cost of approximately $10.3 billion.
