It starts at the city of Zaragoza, passes Lleida and ends at El Vendrell, 70 kilometers west of Barcelona, where it connects with AP-7.

It was a toll road, and forms part of the European route E90.

It is a major motorway in Spain because it is between Barcelona and Madrid.

It was finished at 1977 and was exploited under a concession agreement operated by Abertis.

This concession agreement expired in 2021 and the motorway ownership was transferred to the state, with all tolls throughout the route abolished.
