Communications, trade, and tourism for three countries

The Southern Interoceanic Highway crosses the three natural regions of Peru. It goes across the departments of Madre de Dios, Puno, Cusco, Arequipa, Apurimac, Ayacucho, Moquegua, Ica and Tacna, which make up the Macro Southern Region. 

It has been estimated that there will be an increase of 1.5 percent in the area's GDP  when several development opportunities open up, promoted by the dinamization of communications, trade, and tourism. 

The road will consolidate the interconnection of the Pacific and Atlantic oceans. This means access to new markets  and an increase of trade and tourism between Peru, the  central-western region of Brazil, and the north of Bolivia. At the same time, Brazil and Bolivia will gain access to the ports of Asia through Peruvian ports.

The reduction in travelling times and cargo transportation costs are part of the benefits, especially between the Macro SOuthern Region and the country's maritime ports.

The Macro Southern Region includes 25 percent of the areas protected by the State, and innumerable areas of cultural and historic wealth, a great biodiversity, and natural beauty, which are expected to become tourism destinations for an environmentally sustainable industry. 

This area includes the Manu National Park and the Bahuaja Sonene National Park, the National Sanctuaries Lagunas de Mejía in Arequipa, the National Reserves of Pampa Galeras, Titicaca and  Tambopata-Candamo. Also in the area of influence are the famous Nazca Lines in Ica and the Valleys of Colca and Cotahuasi in Arequipa.
