The current Paso de Agua Negra is the highest border crossing between Chile and Argentina. On the Argentine side, the Agua Negra Pass is located at 4,765m above sea level and 260km from the city of San Juan in the province of San Juan in the north-west of the country. On the Chilean side, the pass lies 229km from the city of La Serena in the Coquimbo region. The pass can be accessed from the Argentine side via National Highway No 150 from the province of La Rioja, which runs for a total of 390km. From the Chilean side, the pass can be accessed by Highway 41 CH which begins in the city of La Serena and is paved up to the customs house.

Because of its altitude, the current pass is subject to frequent closures due to bad weather and this route also poses challenges to drivers even in good conditions. Clearly, the construction of a new route is important to both countries and the new tunnel connection will make a major improvement in transport. The highway project consists of two parallel tunnels that will carry two traffic lanes. The tunnels run for a distance of 13.9km and have a maximum width of 11m but because the tunnels run through high mountains, the maximum incline has been limited to 4%. The Agua Negra Tunnel will be designed for a maximum speed of 100km/h, a maximum cant of 2.5% and with a radius curvature of 1,500m, as well as a maximum longitudinal incline of 3.37%.
