National Route 11 (RN11), known officially as Carretera Juan de Garay, is a road in Argentina, which runs through the provinces of Santa Fe, Chaco, and Formosa.

From its beginning in the Rosario Beltway until it ends at the San Ignacio de Loyola International Bridge, on the border with Paraguay, it covers 980 km (610 mi), fully paved.

In Formosa Province, the 80 km (50 mi) highway is under construction between the intersection with National Route 81 to the north of the City of Formosa and the town of General Lucio V. Mansilla on the shores of the Bermejo River bordering the Chaco Province.

In 1990, the busiest routes in the country were concessioned with toll collections, dividing them into Road Corridors.

The 297 km (185 mi) stretch between the junction with National Route 16, in Resistencia, and the border with Paraguay has been located since 1995 in Road Corridor 28, under the concession system with private financing, that is, without tolls.
