A new audit from the Asociación Española de la Carretera (AEC) published in July 2025, reveals that over 52 % of Spain’s interurban road network, more than 54,000 km out of roughly 101,700 km, shows serious or very serious deterioration. Examples of these damages go from deep pavement cracks and potholes to failing signage, safety barriers, and road markings.
The AEC study estimates that €13.491 billion is required to restore the network, including 33,966 km in need of urgent reconstruction within one year and another 20,407 km requiring repairs in the next four years. According to AEC, lack of sufficient maintenance over recent years has accelerated deterioration at a rate of approximately 8 % per year, while annual investment in road upkeep (~€2 billion) remains far below the recommended €5.2 billion.
