The Carretera Austral (CH-7) is the name given to Chile's Route 7. The highway runs about from Puerto Montt to Villa O'Higgins through rural Patagonia.〔(【引用サイトリンク】language=Spanish )〕 Carretera Austral provides road access to Chile's Aysén del General Carlos Ibáñez del Campo Region and southern part of Los Lagos Region. These areas are sparsely populated and despite its length, Carretera Austral provides access to only about 100,000 people. South of the highway's start in Puerto Montt, Coyhaique (population 44,850〔(【引用サイトリンク】language=Spanish )〕) is the largest city along it. ==History== Construction of the highway was commenced in 1976 under the dictatorship〔http://www.emol.com/noticias/nacional/2013/10/03/622683/textos-escolares-deberan-calificar-el-periodo-de-augusto-pinochet-como-dictadura-militar.html〕 of Augusto Pinochet in order to connect a number of remote communities. Before that, in the 1950s and 1970s, there had been unsuccessful attempts to build access roads in the region.〔(【引用サイトリンク】title=History of the Carretera Austral )〕 It is among the most ambitious infrastructure projects developed in Chile during the 20th century. Carretera Austral has a strategic meaning due to the difficult access by land to a significant portion of Chile's southern territory. This area is characterized by thick forests, fjords, glaciers, canals and steep mountains. Access by sea and air is also a complex task due to extreme winter weather conditions. For decades, most of the land transportation had to cross the border to Argentina in order to reach again Chile's Patagonia. These difficulties were deepened during the 1970s due to the Beagle Conflict crisis. In order to strengthen the Chilean presence in these isolated territories and ensure the land connection to the rest of the country, the government planned the construction of this road, which was executed by the Chilean Army's Engineering Command. More than 10,000 soldiers worked in its construction. Many of them lost their lives during this effort. The highway opened to traffic in 1988, and by 1996 was completed to Puerto Yungay. The last to Villa O'Higgins were opened in 2000. In 2003, a branch road to Caleta Tortel was finished.〔(【引用サイトリンク】title=Carretera Austral )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Carretera Austral」の詳細全文を読む スポンサード リンク
