World's longest tunnel built 8,000 feet beneath French Alps

Published: August 27, 2015


Switzerland has successfully completed work on the world’s longest and deepest railway tunnel, 8,000 feet beneath the French Alps, which will transport passengers from Zurich to Milan. 

The 35-mile long tunnel made with 2 million truck loads of earth and at a cost of £6.5 billion, will transport passengers within two hours and 50 minutes from Zurich to Milan, reducing almost an hour off the current travel time, authorities claimed.

Authorities further said that the NEAT Gotthard Base Tunnel is set to open to the public in June 2016, however, will select 1,000 people to take the maiden voyage in January 2016.


The work on the project began 20 years ago in 1996 with over 2,000 workers hired to excavate more than two million truck loads of earth. Further, the tunnel measures 35 miles and exceeds Japan’s 14.5 mile long Seikan Tunnel, connecting two islands.


Due to the rugged terrain of the alps, massive tunnel boring machines cutting through almost 100 feet of rock on a daily basis were required, consequently eight workers lost their lives in this dangerous process.

According to a Swiss newspaper, safety tests will begin in October. “All scenarios will be considered and tested,” Marco Hirzel of Alptransit Gotthard said during a press conference.


Regardless of the rugged terrain, workers were able to make a completely flat tunnel, enabling trains to travel at more than 150 miles per hour.


“After opening the tunnel, it will be the safest stretch of the Swiss railway network,” Renzo Simoni, CEO of AlpTransit Gotthard said.
