The Swiss have built a 57 km tunnel under the Alps, and it opens June 1st:
[T]he new Gotthard Base Tunnel burrows deep beneath the mountains to connect Switzerland’s German- and Italian-speaking regions, ultimately linking the Swiss lowlands with the North Italian plain. It exceeds the length of its longest predecessor, Japan’s Seikan Tunnel, by a little over three kilometers (1.9 miles). Running at up to 8,000 feet below mountain peaks at times, it also runs deeper below ground level than any other tunnel yet built. So great is the amount of rock and rubble created by the excavation—over 28 million tons—that steep artificial hills have been created in the valleys at the tunnel’s mouth.
Now that trains will run on a specially constructed, almost entirely flat track, trains through the tunnel will be able to reach speeds of 150 miles per hour. This will slash the journey time between Zurich and Milan to just two hours and 30 minutes, considerably faster than the current four hours and 40 minutes. While that’s impressive, shorter hops between sub-Alpine cities aren’t really the new tunnels main raison d’etre, and wouldn’t alone necessarily be worth an injection of over $10 billion.
Why is Europe in generally better shape even though their economy is technically in worse shape? This might be an example.
