Avenida General Paz (official nameRuta Nacional A001 - National Route A001) is a beltway freeway surrounding the city ofBuenos Aires. Roughly following the boundary between the city andBuenos Aires Province, it is one of the few motorways in Argentina that is toll-free. It carries three lanes of traffic in each direction during most of its length, and five lanes between thePan-American Highway and theRío de la Plata. There are feeder roads in both directions and there are service areas along its length, usually with a gas station and fast food restaurants.
The route was the first highway in Argentina, built between 1937 and 1941 with a cost ofm$n 24 million, and officially inaugurated on July 5, 1941.[1]
Federal law number 2,089 of 1887 established the limits of the city ofBuenos Aires, including thepartidos ofBelgrano and the formerSan 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 theAutonomous City of Buenos Aires andBuenos Aires Province.
Named afterJosé María Paz, the freeway was designed byPascual Palazzo and construction was directed byJosé María Zaballa Carbó. It was the first freeway built in the country. The crossings with the most important avenues were grade-separated; more minor cross-streets were served withtraffic circles. The road had four lanes, two on each direction and lateral feeder streets of one lane on each side. The pavement was made ofreinforced concrete.
Works started on 8 June 1937, completed in two stages, the first fromRiachuelo toLiniers (to Ramón Falcón street). The second stage extended from Liniers toRío 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.[1]
In the 1970s the roundabout on Avenida del Libertador was replaced by aninterchange.
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 thecolectivo bus lines travelled on these feeder roads, except theexpress service buses, which stop on these feeders. These streets havespeed bumps that limit speed to40 kilometers per hour (25 mph).
