2. Bolivia’s “Road of Death”
North Yungas Road is hands-down the most dangerous in the world for motorists. If the previous road is just 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. A fatal accident happens there every couple of weeks, 100-200 people perish there every year. In 1995 the Inter-American Development Bank named the La Paz-to-Coroico route “the world’s most dangerous road.”
