The Only Gap in a 30,000 km

A single road runs from Alaska to the tip of Argentina, about 30,000 km. Except for one place: on the border between Panama and Colombia, the asphalt simply stops. Here's why the Darién Gap has never been crossed by a road, and how it stopped explorers, a Scottish colony and a U.S. highway plan, before becoming the path of half a million people on foot.
