A new ‘longest tunnel in the world’ opened today : the Gotthard Base Tunnel, after 17 years of construction, and running 57 km (35 miles) long under the Swiss Alps. It is 8,000 feet, or one-and-a-half vertical miles deep in the earth in some places. The tunnel reduces travel time from Zurich to Milan from 3.5 hours to 2.5 hours. All the more reason for me to go visit Switzerland (I have never been there), and experience the 20 minute tunnel ride! Check out these great pictures from the International Business Times website.
