Autovía 2 Juan Manuel Fangio (also known as Provincial Route 2, formerly National Route 2) is an Argentine dual carriageway, which runs from Buenos Aires to Mar del Plata. The road was a National Route until 1990 when it was transferred to the Government of Buenos Aires Province. The Autovía 2 extends from the junction of Provincial Routes 1 and 36 and National Route A004, just on the traffic circle "Juan María Gutiérrez", which is the limit of Berazategui and Florencio Varela districts. Autovía 2 has two toll booths, one in Samborombón and another in Maipú. The entire road is currently managed by State-owned company "Autopistas de Buenos Aires S.A.", also known for its acronym "AUBASA". More than 30 fuel stations are placed on the route in its entirety. The route has also numerous phone posts to call in case of emergency. Another service is an FM radio station which gives reports about the conditions of the route. Almost all the intersections with other roads are level crossings, without bridges to prevent accidents. There are also two railroad level crossings with General Roca Railway tracks. From Wikipedia
