Paso de los Libres – Uruguaiana International Bridge, Combined road and railway bridge connecting Paso de los Libres, Argentina and Uruguaiana, Brazil

The Agustín P. Justo–Getúlio Vargas International Bridge is a road-rail bridge over the Uruguay River between Paso de los Libres, Argentina, and Uruguaiana, Brazil. Its flat deck runs straight on evenly spaced rectangular piers rising from the water, with no arches, towers or cables; the right end meets a small tree-covered island.

Studies for a binational bridge over the Uruguay River began in 1934–1935, when a mixed Argentine-Brazilian commission chose the Paso de los Libres–Uruguaiana crossing over Alvear–Itaquí and Santo Tomé–São Borja. Work started in 1942, built from both banks by Parodi & Figini in Argentina and Matheus Martins Noronha & Cia in Brazil. The bridge opened to the public on 12 October 1945 and was formally inaugurated on 21 May 1947 by presidents Juan Domingo Perón and Eurico Gaspar Dutra. Until 1997 it was the only crossing on this stretch of the border, carrying 80% of road traffic between the two countries.

The bridge carries the names of two national leaders—Agustín P. Justo from Argentina and Getúlio Vargas from Brazil—reflecting the political partnership between the nations. As you cross, you encounter these names as a reminder of the shared history binding the two countries.

The structure serves as a border crossing and operates daily with international cargo trucks, passenger vehicles, and railway transport. When crossing, allow extra time for processing, especially during peak hours and holidays.

Until 1997 this was the only bridge crossing the Uruguay River on the Argentine-Brazilian border, carrying 80% of the heavy road traffic between the two countries. A parallel span for freight was studied from 2008, and in 2011 the mayors of Paso de los Libres and Uruguaiana signed an agreement to push the project forward.
