National Route 1, also known as Buenos Aires–La Plata Highway and officially called Autopista Doctor Ricardo Balbín since 2004, connects the Autopista 25 de Mayo in Buenos Aires with 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 and Ensenada.
The origins of this road go back to the Plan Director para Capital Federal y lineamientos estructurales para el Area Metropolitana y su región (Directing Plan for Capital Federal and structural guidelines for the metropolitan area and region) written by Buenos Aires City Hall between 1958 and 1965, where they describe, among others, a coastal highway between the cities of Tigre and La Plata.
The road planned after studies done starting in 1964 was accepted as it required the least expropriations.
As the roadbed coincided in part with Acceso Sudeste which was a federally administered road, when defining the routing of the Autopista Buenos Aires–La Plata, the Federal Department of Public Works (Secretaría de Estado de Obras Públicas de la Nación) and the Buenos Aires Province Ministry of Public Works (Ministerio de Obras Públicas de la Provincia de Buenos Aires) took part in the discussions and planning.
