context_page_description: The Autovía A-23 is a motorway in Aragon, Spain.
  A-23 is an upgrade of the N-330 and N-234. As of June 2020, it starts in the province of Huesca then runs south to Zaragoza. Then, it follows the Jiloca River 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 where a 8.6-km two-lane cross-border tunnel has been in operation since 2003. The freeway is also known as Autovía Valencia-Francia or Autovía Sagunto-Somport.
  Once fully complete, it will serve as an important connection between Valencia, Aragon, the Basque region, and France, through the Somport tunnel. The highway's nickname is "spine of Aragon" since it runs along the north-south through the region.
  The A-23 runs through the corridors of the N-234, between Sagunto and Retascón and the N-330 between Retascón and Jaca. The road is new and independent of national roads with two exceptions, one being 10 km from Viver, and the other between Nueno and Monrepós, about 75 km south of Somport using parts of the N-330 to cross the difficult terrain of the Pre-Pyrenees mountains. This was the most expensive portion of the highway to build.
