Built as a strategic military route, the 90 km of twists and turns run North to South across the tallest sections of the Carpathian Mountains, between the highest peak in the country, Moldoveanu, and the second highest, Negoiu. The road connects the historic regions of Transylvania and Wallachia, and the cities of Sibiu and Piteşti.
