Avenida del Libertador (Buenos Aires)

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.

Bella Vista Street was widened and lengthened, reaching 7 km (4.3 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).

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.

In Núñez, it passes by the infamous Navy Mechanics School, which housed the most important of the 340 detention centers operated by Argentina's last dictatorship in the late 1970s.

An underpass then leads into the northern suburb of Vicente López, beginning the avenue's 15 km (9 mi) stretch in Buenos Aires Province.
