They Just Finished Digging the World's Longest Tunnel

When Swiss engineers aren't burrowing out spaces for large hadron colliders, they're off digging train tunnels. Really, really long train tunnels.


When Swiss engineers aren't burrowing out spaces for Large Hadron Colliders, they're off digging train tunnels. Today they finished drilling the Gotthard Base Tunnel, which is 33.5 miles long and expected to cut ground travel time between Zurich and Milan by 1.5 hours. Trains will zip through it at 155 miles per hour.

Here in Los Angeles, we're still trying to get the subway extended from downtown to the beach.


The BBC has a great series of photos of the drill breaking through the last few feet of rock. You can take a look at those photos here.
