Avenida del Libertador is one of the principal thoroughfares in Buenos Aires, Argentina, and in points north, extending 25 km (16 mi) from the Retiro District of Buenos Aires to the northern suburb of San Fernando. ==History== Inspired by Parisian urbanist Baron Haussmann's renowned modernization of the City of Lights, Mayor Torcuato de Alvear took office with a similar mandate in 1880. Inheriting a rapidly growing city hamstrung by a typically colonial grid of narrow streets, his most ambitious project would be a boulevard connecting the Retiro section (north of downtown) to the growing neighborhoods of Recoleta and Palermo to the northeast (at the time merely suburbs). Bella Vista Street was widened and lengthened, reaching 7 km (4.5 mi) northwest into Palermo and, upon its inaugural in 1885, was renamed in honor the Mayor's father, Carlos María de Alvear (one of Argentina's early leaders). Soon becoming among the most coveted addresses in Buenos Aires, Avenida Alvear was graced by numerous mansions (a few of which survive), though it quickly also became among the most transited in the fast-growing Buenos Aires of the late 19th century. Planned with a future railway terminal in Retiro in mind, Mayor Adolfo Bullrich had a multilane boulevard developed between Retiro and Palermo, roughly parallel to the Mitre rail line and east of Alvear Avenue, giving Palermo commuters easy access to the station and freeing Alvear of its heavy traffic. Opened in 1906, Avenida Viceroy Vértiz was renamed ''Avenida del Libertador'' in 1950 in honor of the Liberator of Argentina, Chile and Perú, General José de San Martín, by order of President Juan Perón and to commemorate the hundredth anniversary of San Martín's passing. A 15 km (9 mi) thoroughfare (Route 195) connecting Buenos Aires to San Fernando was built in the late 1930s and was likewise renamed in 1950. The subsequent automobile boom and the growth of northside neighborhoods and suburbs led Mayor Manuel Iricíbar in 1968 to order the extension of the avenue northwards into the Belgrano and Núñez neighborhoods. The extension was facilitated by a tunnel and by the widening of Blandengues Street, which became part of Avenida del Libertador. Thus connected to the avenue of the same name north of Buenos Aires, Libertador's entry into the suburb of Vicente López via a roundabout was replaced by a freeway underpass and its boulevard medians, removed. Severe rush hour traffic congestion along the avenue was alleviated by the 1996 opening of the Arturo Illia Freeway, running parallel to the avenue and providing a (toll road) alternative to the busy junction at Libertador and Avenida 9 de Julio. 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「Avenida del Libertador」の詳細全文を読む スポンサード リンク
