List of primary highways in Catalonia
The network of primary highways (freeways or not) in Catalonia, Spain, can be divided into two groups: highways managed by the Spanish Government and highways managed by the Generalitat de Catalunya (Catalonia's Government). The first group are itineraries included in the Red de Interés General del Estado (Spanish highways network), which generally either serve as long-distance connectors beyond the Catalonia's field or either have a special strategical importance.
