The Yungas Road, popularly known as The Death Road, is a 64-kilometre (40 mi) long cycle route linking the city of La Paz with the Yungas region of Bolivia. It was conceived in the 1930s by the Bolivian government to connect the capital city of La Paz with the Amazon Rainforest in the north part of the country. Large parts of it were built by Paraguayan prisoners during the Chaco War. Several sections of the road are less than 3 metres (9.8 ft) wide, and due to presence of rain, fog, landslides, cascades, steep slopes and cliffs that drop more than 610 meters or 2000 feet, it is largely considered the most dangerous road in the world.^[1][2][3] Since 1994, nearly 300 drivers and passengers are reported to have died there annually.

Unlike in the rest of the country, The Yungas Road is a left-hand traffic road, which allowed drivers to better gauge the distance between their vehicles and the edge of the road.^[4] It has since been replaced by a newer, two-lane asphalt road featuring guardrails and drainage systems.^[5]

Known for its extreme danger with 3,500 metres (11,500 ft) of descent, the Death Road draws about 25,000 tourists per year and has become a popular destination for adventure tourism, particularly mountain biking.^[6][7] At least 18 cyclists have died on the road since 1998.^[8]

Parts of this road were built by Paraguayan prisoners that were captured after Chaco War in 1930s. It was of one of the few routes that connect the Amazon jungle up north, with the city of La Paz.^[9]

A new alternative route, now part of Route 3, was built during a 20-year period ending in 2006. The modernization included enlarging the carriageway from one to two lanes; asphalt paving; bridges, drainage, guardrails, and the building of a new section between Chusquipata and Yolosa, bypassing the most dangerous sections of the original road. As the result, North Yungas Road is now mainly used for bicycles, motorcycles, and walking. Up until 2006, the North Yungas Road was the sole route for traveling from Coroico to La Paz. In 2009, the Bolivian government built a new road along the adjacent mountain range.^{[citation needed]} The asphalt road features two lanes, drainage systems and guardians.

Because of the steep slopes, the lack of guardrails, and the narrow width of the road (as little as 3 meters in some places), the road was especially dangerous for vehicular traffic. Weather conditions further increased the danger; rain and fog would reduce visibility, while muddy terrain and loose stones could impair traction. It was famous for its dangerous conditions and deaths from traffic accidents, averaging around 209 accidents and 96 deaths per year.^[10] In 1995, the Inter-American Development Bank dubbed it as the most dangerous road in the world.

In July 1983, a bus fell from the Yungas Road into a canyon, killing more than one hundred passengers in one of the worst road accidents in Bolivia.^[11]

Until the mid-1990s, the accident rate was even worse, with 200 to 300 drivers falling off the cliff each year.^[12]

In 2011, the total number of accidents was around 114, the second most in Bolivia after the road between La Paz and Oruro. Of these accidents, 42 people died.^[13]
