Successful talks have been held between Chile and Argentina with regard to the Agua Negra Tunnel that will link the two countries. The project looks set to cost US$1.37 billion to construct, according to Business News Americas. The majority of the planned route, 72%, lies in Argentina and the country will provide the bulk of the funding required; some $986 million. Chile will provide the remaining $384 million. The agreement was struck between the Publics Works Ministries of the two countries. Further details have now to be agreed for the tunnel, which at 13.9km will be Latin America’s longest tunnel. The tender process could be opened later this year, with construction activity then commencing in 2015. Construction is expected to take 7-8 years and although details have not yet been released, drilling and blasting seems the likely method for excavation. The new tunnel will reduce travel times between the two countries as the distance will be cut by around 44km over existing routes. The project will also help trade between Argentina and Chile.
