The Autovía A-23 is a motorway in Aragon, Spain. A-23 is an upgrade of the N-330 and N-234. Presently, it starts in Huesca then heads south to Zaragoza. Thereafter it follows the rio Jiloca south to Teruel through the Sierra d'Espada to the coast at Sagunto. Plans call for the freeway to reach the French border at Somport. The freeway is also known as Autovía Valencia-Francia or Autovía Sagunto-Somport. Eventually, once fully complete, it will serve as an important axis of connection between Valencia, Aragon, the Basque region and France through the Somport tunnel . It's nickname is the "spine of Aragon" since it runs along the north-south community intercommunicating the three capitals. The A-23 runs through the corridors of the N-234 , between Sagunto and Retascón and the N-330 between Retascón and Jaca , though the whole layout of the road is new and independent of national roads except two small sections, one 10 km from Viver and Barracks (Ragudo rise) and another about 30 km complicated port to save the Pyrenean the Monrepós which is the most expensive portion of the entire highway, which is currently under construction. ==Name== Its name is derived from, like almost all conversions of national roads to highways, the first two figures of the old name (N- 23 4> A- 23 ), and the letters A reference to a motorway belonging to the Ministry of Development . The A-23 also has European nomenclature , as part of the European route E07 , which connects Pau , southern France , with Zaragoza . In the French section, the route is called RN134, which connects Pau to Oloron-Sainte-Marie and Spain. 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「Autovía A-23」の詳細全文を読む スポンサード リンク
