La Margineda Bridge is the largest mediaeval bridge still preserved in Andorra.
It is located on the road that formerly went from Sant Julià de Lòria to Andorra la Vella (and is now to the east of the La Margineda roundabout). The structure passes over the River Valira, the main river in the country. It is 33 metres long and has a single nine and a half metre span.
Next to the bridge there is a modern sculpture by the Valencian Vicenç Alfaro to commemorate the First Language and Literature of Catalonia Congress. The two arches together represent Andorra’s past and present.
