National Route 9 (in Spanish, Ruta Nacional 9) is a major road in Argentina, which runs from the center-east to the northwest of the country, crossing the provinces of Buenos Aires, Santa Fe, Córdoba, Santiago del Estero, Tucumán, Salta and Jujuy. It starts on Avenida General Paz, which marks the border between the Autonomous City of Buenos Aires and the surrounding province of the same name, and ends at the Horacio Guzmán International Bridge, on the La Quiaca river, traversing 1,967 km (1,222 mi). The road is a limited access motorway from Buenos Aires to Rosario.
Between the cities of San Nicolás de los Arroyos and Rosario (distant about 65 km (40 mi) from each other), the road is named Teniente General Pedro Eugenio Aramburu.
The route originated as the "Camino Real del Perú" (Royal Road of Peru), used since colonial times to travel from Buenos Aires, through Córdoba, Santiago del Estero, San Miguel de Tucumán, Salta, San Salvador de Jujuy, and Potosí, continuing to Perú. The section between Buenos Aires and the south of what it is today Cordoba Province, was shared with the "Camino Real del Oeste" (Royal Road of the West) which branched towards San Luis, Mendoza and Santiago (Chile). The road had a system of small inns and establishments every 30–50 km where travellers could rest.
