Argentina and Chile have agreed to finance the Agua Negra tunnel project, which will connect both countries, by direct investment.
Each country will finance the infrastructure located in its territory. Twenty eight per cent of the tunnel is located in Chilean territory and the rest in Argentine territory.
The total project investment is estimated at US$850 million. The period to develop the project would be 10 years, 2 for the design and engineering studies and the remaining 8 years for construction.
In July 2013, the two countries, launched a Request for expressions of Interest to build the Agua Negra tunnel. Later in October 2013, 23 companies or teams expressed interest.
The list of companies/teams interested in the project is the following:
The project will have two parallel tunnels, one for each direction, 13.9 km in length. The Argentine entrance will be at altitude of 4,085 meters, and the Chilean entrance at 3,620 meters.
It is strategically located within the central belt of both countries and was considered a high-priority investment, because it attracts traffic itself that does not compete with any other road.
El Paso de Agua Negra is one of the 13 projected roads that Chile and Argentina have agreed to receive preferential budgetary attention, for the purpose of improvement. The 13 projects have a total investment estimated at US$2200 million. This investment plan is expected to be completed by 2030.a
