The Guadiana International Bridge (Spanish: Puente Internacional; Portuguese: Ponte Internacional) is a bridge that crosses the Guadiana River connecting southern Spain (town of Ayamonte) and Portugal (town of Castro Marim). It is not split evenly between the two countries, with a greater share of it situated in Portugal. Completed in 1991, its structural type is a cable-stayed bridge, with a deck of prestressed concrete. The bridge is open to vehicles only.
The bridge is 666 metres long with the central span between the towers being 324 metres. The deck stands 20 metres above the river, allowing the navigation of ships of deep draft. The two towers of the bridge are 95 and 96 metres tall, respectively. The Spanish side tower rests on an artificial island built on the riverbed, while the pillar on the Portuguese side is on land.
The bridge connects the Via do Infante de Sagres A22 motorway in Portugal to the Autopista del Quinto Centenario A-49 motorway in Spain, and is part of the European route E01.
