History

Federal law number 2,089 of 1887 established the limits of the city of

, including the partidos of Belgrano and the former San José de Flores (now Barrio Flores). In Article 6 of that law it declared that a road was to be built to delimit these with the city of Buenos Aires. Due to the plan of drawing straight lines for the road, an exchange of land was made between the Autonomous City of Buenos Aires and

. Works started on 8 June 1937, completed in two stages, the first from Riachuelo to Liniers (to Ramón Falcón street). The second stage extended from Liniers to Río de la Plata. Works were supervised by Dirección Nacional de Vialidad (the National office that controlled the routes in the country) and carried out by three private companies, "Empresa Argentina de Cemento Armado", "Compañía de Construcciones Civiles S.A.", and "Empresa Sabaría y Garassino Ltda." The freeway was opened to the public on 5 July 1941. In the 1970s the roundabout on Avenida del Libertador was replaced by an interchange. In 1996 the road was modernized and fully grade-separated, widening the road to three lanes on each direction and two feeder streets with two lanes each. To facilitate traffic it was decided that the colectivo bus lines travelled on these feeder roads, except the express service buses, which stop on these feeders. These streets have
