National Route 9 (in Spanish, Ruta Nacional PY09, better known as Ruta Transchaco) is a national highway in Paraguay, which crosses the Paraguayan Chaco, crossing the departments of Presidente Hayes, and Boquerón. It starts at the Argentinian border in José Falcón and ends at the Bolivian border in Fortín Sgto. Rodríguez, traversing 7800NaN0.
It is important to note that the last 1300NaN0, or so, of the route from Asunción to the Bolivian border which is shown on the accompanying map, no longer represents the de facto highway between Paraguay and Bolivia. Coming from Asunción the actual asphalt highway turns left (south-west) at a place on Ruta 9 called Estancia La Patria ( -21.3521°N -61.5221°W ).[1] After turning left the asphalt highway continues south-west and west for 1150NaN0 to cross the Paraguay-Bolivia border at -21.6726°N -62.458°W. From there 1100NaN0, or so, of good quality gravel road leads to the first substantial Bolivian town, Villamontes.[2]
