The Most Dangerous Roads Around The World. North Yungas Road is hands down the most dangerous in the world for motorists. If other roads could be considered impassable, this one clearly endangers your life. It runs in the Bolivian Andes, 70 km from La Paz to Coroico, and plunges down almost 3,600 meters in an orgy of extremely narrow hairpin curves and 800 meter abyss near misses.
