National Route 1

Route in Argentina

National Route 1, also known as Buenos Aires–La Plata Highway and officially called Autopista Doctor Ricardo Balbín since 2004, is a highway that connects the 25 de Mayo Highway and Paseo del Bajo in the city of Buenos Aires with the Provincial Route 11, near the city of La Plata. It has a length of 50 km (31 mi) with two or four lanes on each direction in different areas, and is indicated in red in the map. On km marker 31 it connects with National Route A004, the main road to the coastal tourist areas of Mar del Plata and others in Buenos Aires Province. The highway runs (from northeast to southeast) through the partidos of Avellaneda, Quilmes, Berazategui, Ensenada, and La Plata. This highway is currently operated by AUBASA ("Autopistas de Buenos Aires S.A."), a state-owned company owned by the Government of Buenos Aires Province, which also manages most routes to the cities of Costa Atlántica.[citation needed] From Wikipedia
