The AP-7 motorway is the backbone of the country. The other roads are limbs of a structured body. The AP-7 was designed with sufficient quality (compare it to the A-2 in Lleida) and has been a toll road for 50 years, extended by the addition of a third lane (and, consequently, by extension on the C-32). The only ministerial magnanimity was the addition of a fourth lane on the Vallès section and the removal of the Bellaterra toll, by which time more cars were already using the side lanes than the main carriageway. Today, the AP-7 serves as a major connector between the entire Iberian Peninsula, Europe, and Morocco. Heavy goods vehicles account for more than a quarter of the total traffic. Every day, the AP-7 carries up to 13,000 trucks through La Jonquera, and more than 25,000 travel along the central section in Vallès.
