Yungas Road, Bolivia's Deadliest Byway

NORTHEAST OF LA PAZ, BOLIVIA - MAY 31: A 56 kilometer road from La Paz to Coroico in the Yungas region of Bolivia. In 1995 the Inter-American Development Bank christened it as the "world's most dangerous road". In 2006, one estimate stated that 200 to 300 travelers were killed yearly along the road. The road includes graves and markings on many of the spots where vehicles have fallen. The largely single-lane road has no guard rails and cliffs of up to 600 meters (2,000 feet). Most of the road is the width of a single vehicle, about 3.2 meters (10 ft). The danger of the road made it a popular tourist destination starting in the 1990s, drawing some 25,000 thrillseekers. Mountain biking enthusiasts in particular have made it a favorite destination for downhill biking since there is a 64-kilometer (40 mi) stretch of continuous downhill riding with only one short uphill section.
