6. Jalalabad–Kabul Road, Afghanistan
Many roads have been dubbed “most dangerous,” but the 65-kilometer stretch of highway from Jalalabad to Kabul has more claim than most, snaking through Taliban territory. But it’s not the threat of insurgency that makes Highway so dangerous. It’s a combination of the narrow, winding lanes that climb up to 600 meters through the Kabul gorge and the reckless Afghan drivers trying to overtake the heavily-burdened haulage trucks.
