Construction of the motorway, originally known as the A-9, began in the mid-1970s with the section between Pontevedra and Vigo, including the
Rande Bridge, and also the section between A Coruña and Santiago de Compostela. The latter opened in 1979, the former two years later. Between 1988 and 1992, these two sections were gradually linked. In 1994, construction of the spur to Ferrol commenced. In the late 1990s, the A-9 was extended from Vigo to what is now the junction with the Autoestrada AG-57. Then, in the early 2000s, it was extended from this point to Tui. The spur to Ferrol was completed in 2003, and in the same year the A-9 was redesignated the AP-9, as part of the
general redesignation of Spanish autopistas and autovías. ==Gallery==
