In the country of Bolivia is a truly amazing road carved into the side of a cliff.
Stremnaya road and Yungas Road is called the road of death.

The North Yungas Road (also Grove’s Road, Coroico Road, Camino de las Yungas,
“El Camino de la Muerte”, “Death Road”) is a 38 to 43 mile road (depending on source)
leading from La Paz to Coroico, 35 miles (56 km) northeast of La Paz in the Yungas
region of Bolivia. It is legendary for its extreme danger, one estimate is that nearly 100
travellers annually have died along the road — the road moreover includes Christian
crosses marking many of the spots where such vehicles have fallen.
The road descends from approx. 14,100 ft (4300 m) to 6200 ft (330 m), transitioning
quickly from cool altiplano terrain to rain forest as it winds through very steep hillsides
and atop cliffs.
