Uruguaiana is a municipality in the Brazilian state of Rio Grande do Sul. It is located on the left-hand (eastern) shore of the Uruguay River that forms the border with Argentina. Opposite Uruguaiana, and joined to it by a road/railway bridge, lies the Argentine city of Paso de los Libres, Corrientes. North of Uruguaiana lies the Brazilian municipality of Itaqui, connected by a bridge constructed by the English in 1888 over the Ibicuí River. The municipality also borders the municipalities of Alegrete, Barra do Quaraí and Quaraí, and, also, Uruguay, making it one of the few international triple-border municipalities of Brazil.
The city marks the southernmost point reached by the Paraguayans in the Paraguayan War; after being taken without resistance, it was recaptured after a six-week siege that effectively ended the phase of Paraguayan offensive operations.
Nowadays, Uruguaiana represents the biggest in population and arguably most important municipality of the sparsely populated western Rio Grande do Sul.

Remarkable construction works
Later, on May 21, 1947, the International Getúlio Vargas/Agustín P. Just Road/Railway Bridge on the Uruguay River was inaugurated by presidents Eurico Gaspar Dutra of Brazil and Juan Domingo Perón of Argentina, linking Uruguaiana to the Argentine city of Paso de los Libres. At the time of its construction, the bridge was the greatest work of engineering of Latin America.
Since 1987 there is a high-voltage direct current (HVDC) back-to-back station for power exchange with Uruguay at Uruguaiana. This facility, which was built by Toshiba, can transfer a maximum power of 53.9 megawatts. The applied DC voltage is 17.9 kV.
