List of national roads in Spain

The Carreteras Nacionales de España or National Roads of Spain are roads of governmental property, managed by the Ministry of Fomento and conform the Red de Carreteras del Estado or State Roads Network. The road numbering scheme is normalized according to the rules set by the fourth Plan General de Carreteras (General Road plan) of 1939-1941 (Plan Peña). The territory (without the Canary Islands and Balearic Islands) is divided into 6 radial sectors, whose boundaries are the radial roads that link Madrid to the coasts and borders. These radial roads follow a clockwise system:

Now, these roads have been upgraded to Autovías, changing their names to its geographical heading instead of using the city they link to Madrid, and not varying their number (A-1, A-2,...). The codes for the national roads consist of 3 numbers (e.g.: N-XXX, where X is a number) assigned as follows:

If the road is radial, the beginning will be the closest end to Madrid. However, if it is a transversal road, it will start in the end that makes an anti-clockwise direction. Example:

Some exceptions may exist if the road is within Basque Country or Navarra limits, where other numbering scheme applies (e.g.: N-102)
