The Ruta Nacional 9 ( Buenos Aires - La Quiaca ) is a national road in Argentina. It is also known as the Panamericana as it is part of the network of the same name. Its length is 1830 kilometers; it is one of the longest numbered streets in the country.
The road has a long history, since it was the main connection route between the mining town of Potosí and the then most important overseas port of Buenos Aires from the time of the viceroyalty of the Río de la Plata . It used to be called the Camino Real (Royal Way).
course
The road begins as a toll motorway on the inner ring road of Buenos Aires , the Avenida General Paz , and leads - known as Acceso Norte - first through the north-western suburb of this city, then further parallel to the Río Paraná to Rosario . From there it continues to the west. After bypassing Villa María , you will reach the city of Córdoba . As far as Córdoba, the road is built like a motorway.
In Córdoba, the road turns north and leads through Jesús María and Santiago del Estero to San Miguel de Tucumán , where it is also expanded to four lanes over a short stretch. After Rosario de la Frontera and Metán , Salta is reached.
From Salta the road leads on a winding stretch through the subtropical cloud forest to San Salvador de Jujuy . This section is also known as the Cornisa . Because of the many curves on the route between Salta and Jujuy, many prefer to use the route via Ruta Nacional 34 and Ruta Nacional 66 .
Behind Jujuy, the road leads through the Quebrada de Humahuaca gorge . It goes around Tilcara and Humahuaca , the two most important cities of the gorge. Then there is a steep ascent to the Puna plateau . At Tres Cruces , the highest point of the road is reached at 3750 meters above sea level, from there on the road continues relatively flat.
In Abra Pampa the road joins the Ruta Nacional 40 , the longest national road in the country. This is where the last section of the route begins, which leads almost straight north to the border town of La Quiaca , which is connected to the Bolivian Villazón via the “Horacio Guzmán” bridge .
The continuation of the Ruta 9 in Bolivia, the Ruta 14 , leads over Tupiza almost to Potosí .
particularities
In almost all cities, the Ruta Nacional 9 originally had a different course than it is today. These include the metropolitan area of Gran Buenos Aires , Rosario , Córdoba and San Salvador de Jujuy , where parts of the originally inner-city national road have been converted into bypasses and expressways.
