The road is entirely part of the European route E5. It mostly follows the path of the former N-4 road, crossing the provinces of Madrid, Toledo, Ciudad Real, Jaén, Córdoba, Seville and Cádiz.

Between Seville and Cádiz, the highway is known as Autopista AP-4, extending over 123.80 km. AP-4 used to be a toll road before 1 January 2020. The original N-4 in this section remained in service as a free option for this reason.

The construction works required major engineering work to tunnel through Despeñaperros Natural Park in the Province of Jaén, which separates the autonomous communities of Andalusia and Castilla-La Mancha. Construction started in the 1960s, reaching the city of Seville in 1992 and the Province of Cádiz in the 2000s.
