11 Mack trucks, each with a 28-liter V12 Cummins diesel engine under the hood, hauling over three million pounds of cement and steel into the freezing Arctic Circle, 1,500 miles away from civilization.

Sounds a bit crazy, doesn’t it? But amid the bleak 1950s, when North America was under the threat of a nuclear showdown with the Soviet Union, the West’s solution was the so-called Distant Early Warning Line, or DEW Line, which consisted of 63 manned radar stations about 200 miles north of the Arctic Circle.

And, well, construction material had to be hauled into the freezing terrain somehow.
