 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 thoroughfare (Route 195) connecting Buenos Aires to San Fernando was built in the late 1930s and was likewise renamed in 1950.
