The Autopista AP-9 (also known as ''Autopista del Atlántico'') is an autopista in Galicia, Spain. It starts in A Coruña and runs south past the cities of Santiago de Compostela, Pontevedra and Vigo, before ending at the town of Tui, a few kilometres north of the Portuguese border at the Minho River. The AP-9 is 178 km (111 miles) in length. The first 16 km (10 miles), from A Coruña to the Autovía A-6 near the towns of Guísamo and Betanzos, form part of European route E70, while the remainder forms part of European route E01. Between A Coruña and Vigo, the autopista runs parallel to the N-550 road, and between Vigo and Tui it runs parallel to the Autovía A-55. The AP-9 has two spurs: the 36 km (22.5 mile) long AP-9F from Guísamo to Ferrol, which runs parallel to the N-651 road and also forms part of European route E01; and the 4 km (2.5 mile) long AP-9V, which runs into the centre of Vigo. ==History== Construction of the autopista, 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Autopista AP-9」の詳細全文を読む スポンサード リンク
