Chile-Argentina tunnel project moving ahead

So far 18 companies have been registered as eligible for tenders in the Agua Negra Tunnel project, which will link Argentina with Chile. The tender process is commencing for the project in the second half of 2014. The new tunnel will provide a better alternative to existing routes connecting the two countries through the Andes Mountain range at present. One of the existing routes is through a high mountain pass, which is frequently blocked due to poor weather while being unsuitable for heavy vehicles. The other route, a tunnel, is also at altitude and can suffer blockages in poor weather.
