San Ignacio de Loyola International Bridge, Iron bridge at Clorinda-José Falcón border crossing, Argentina-Paraguay.

The San Ignacio de Loyola International Bridge is a prefabricated modular steel bridge of the Acrow type, 70 m long with an 8 m wide roadway, spanning the Pilcomayo River between Clorinda, in Argentina's Formosa Province, and José Falcón in Paraguay's Presidente Hayes department. It is the only direct vehicular link between the two countries, and paved road runs from it to Asunción, 42 km away.

The bridge is named after Ignatius of Loyola, founder of the Society of Jesus, whose order explored the area and established missions that later became towns. It carries Argentine National Route 11, which runs 980 km from Rosario to Clorinda, and links to Paraguay's Route 12 toward Asunción. Crossings were restricted to cargo during the COVID-19 pandemic; the bridge reopened on 13 December 2021 after two years of closure, together with the river crossings between Alberdi and Puerto Formosa.

The bridge is named after Ignatius of Loyola, founder of the Society of Jesus. The Jesuits explored this area and established missions that later grew into towns and cities, the Jesuit Reductions.
