Most of the high capacity roads in Spain are under the authority of the General Roads Directorate (Sp. "Dirección General de Carreteras") of the Ministry of Public Works, a department of the central Government of Spain, with the exceptions of Navarre and the Basque Country, the only autonomous communities which have been transferred full powers over all roads in their territories. Usually, the DGC manages all road maintenance, but in the case of the tolled "autopistas", the management is commonly delegated to the concessionaire company.
