Río Gallegos, Santa Cruz in the context of Güer Aike Department

Néstor Carlos Kirchner ([ˈnestoɾ ˈkaɾlos ˈkiɾʃneɾ] ; 25 February 1950 – 27 October 2010) was an Argentine lawyer and politician who served as the president of Argentina from 2003 to 2007. A member of the Justicialist Party, he previously served as Governor of Santa Cruz Province from 1991 to 2003, and mayor of Río Gallegos from 1987 to 1991. He later served as first gentleman of Argentina during the early tenure of his wife, Cristina Fernández de Kirchner, the first person to serve in this role. Ideologically, he identified himself as a Peronist and a progressive, with his political approach called Kirchnerism.

Born in Río Gallegos, Santa Cruz, Kirchner studied law at the National University of La Plata. He met and married Cristina Fernández at this time, returned with her to Río Gallegos at graduation, and opened a law firm. Commentators have criticized him for a lack of legal activism during the Dirty War, an issue he would involve himself in as president. Kirchner ran for mayor of Río Gallegos in 1987 and for governor of Santa Cruz in 1991. He was reelected governor in 1995 and 1999 due to an amendment of the provincial constitution. Kirchner sided with Buenos Aires provincial governor Eduardo Duhalde against President Carlos Menem.

National Route 40, also known as RN40 or "Ruta 40", is a route in western Argentina, stretching from Cabo Vírgenes near Río Gallegos in Santa Cruz Province in the south to La Quiaca in Jujuy Province in the north with approximately 5194 km length. The route parallels the Andes mountains. The southern part of the route, by now largely paved, has become a well-known adventure tourism journey, and there are plans to pave the whole road.

RN40 is the longest route in South America and one of the longest in the world alongside such routes as U.S. Route 66, Canada's Trans-Canada Highway, and Australia's Stuart Highway, more than 5,000 kilometres (3,100 mi) long. At its traditional southern end near the city of Río Gallegos, it starts at sea level. It then crosses 20 national parks, 18 major rivers, and 27 passes in the Andes. Route 40's highest point is 5,000 m (16,404 ft) in Abra del Acay in Salta Province.
