Unfortunately, the entire article is not online. From the New Yorker abstract:
The defining project of Herrenknecht’s career and one of the greatest public works of any kind is the Gotthard Base Tunnel, in Switzerland. The tunnel, which has been under construction since 2002, will run a distance of more than thirty-five miles. When completed, in 2017, it will be the longest traffic tunnel in the world.After reading, I was compelled to look at Martin's website as I needed to see the machines he is so enraptured with. Turns out you can buy a used model for your personal tunnel digging needs!
