Gotthard Base Tunnel:World's Longest Railway Mountain Tunnel
Subscribe/Renew Journal
Switzerland was suffering from serious traffic problem and so it proposed a gigantic project. Over 35 miles long tunnel would cut through the heart of the Swiss Alps. Redirecting the rush and traffic of Europe not over the Alps but under the Alps. To do this, miners had to punch their way through the hardest rock on this planet. For this a TBM was required, each 3 stories high and larger than 4 football fields, working continuously for 6 years. This project was very dangerous and outrageously expensive at a price tag of $10 billion.
