The bridge over the Douro River on the La Plata Motorway had a very large separation between the carriageways. This is the reason why the idea of building a single, four-armed pier was replaced by two bridges with two separate piers. The separation between the axes of the two carriageways amounts to 20.5 m and the bridge is longitudinally divided into six spans of 34.5 m +36 m +49.5 m +72.00 m +49.5 m +34.5 m.
