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. They are mainly autopistas (ca|autopistes) or autovías (Catalan: autovies) but some regular roads can also be found (most of them are in process or in prospect of being upgraded to autovía).
The second group are itineraries mainly used for Catalonia's internal transport. However, some of these highways (such as C-31, C-32 or C-58) are main communication paths and suffer from heavy traffic.
The following highways (freeways or not) are managed by the Spanish Government. The list is arranged by itineraries, some of them formed by sections of different categories. The category field indicates if the sections are autopistas (generally tolled freeways under a concession contract), autovías or simple single-lane roads.
