The World's Most Dangerous Roads: 8 Extreme Routes That Challenge Every Driver

Karakoram Highway, Pakistan–China

This highway links Islamabad to Kashgar, crossing the Karakoram Range at Khunjerab Pass, the highest paved border crossing on Earth. Its construction came at a brutal human cost: more than 900 workers died building it, roughly one death for every 1.5 kilometers of road. A major landslide in 2010 submerged 22 kilometers of the highway under a new lake, forcing a bypass and boat crossings that are still in use today.
