Answer:
The Gotthard Tunnel has opened up transportation in Europe. For the first time, there is a continuous high-speed rail network connecting the North Sea to the Mediterranean. The region where the tunnel is located is rugged and difficult to cross. What used to take several days on foot in the 1800s now takes only 20 minutes on 155-mile-per-hour trains. The travel time between places like Zurich, Switzerland, and Milan, Italy, is cut down by about an hour and a half.
