The Agua Negra Pass (Spanish: Paso de Agua Negra) is a pass over the Andes mountains which connects Argentina and Chile. The highest point of this pass is at 4,780 m (15,680 ft) AMSL.[1]

Agua Negra Tunnel

To improve trade between Chile and Argentina, a 14 km, three-bore vehicular tunnel (two for traffic and one for ventilation[2]) below the pass is planned, which will allow year-round traffic.[3][4] (The pass is closed for much of the winter.)

In March 2015, Argentina officially approved the project.[5] It is awaiting ratification from Chile.

Also planned for the deepest part of the tunnel is the Agua Negra Deep Experiment Site (ANDES):[2] an underground laboratory. Because all currently operating deep underground laboratories are located in the Northern Hemisphere, a Southern Hemisphere site would have some unique benefits:
