Présentation

• La route nationale 522, ou RN522, est une ancienne route nationale française qui reliait Saint-Jean-de-Bournay (RN502) à Lancin (RN75).

Historique

Généralités

• A sa création, en 1933, elle est définie comme la route de Saint-Jean-de-Bournay à Lancin.
• Elle est issue des chemins de grande communication Gc25 de Saint-Jean-de-Bournay à Bourgoin, Gc65 de Bourgoin à Flosaille et Gc68 de Flosaille à Lancin dans l'Isère.
• Son tracé est modifié dans la traversée de Bourgoin-Jallieu en 1970, à l'occasion de la mise en service de la déviation de la RN6, dont une partie de l'ancien tracé est reprise pour la nouvelle RN522.
• Elle est intégralement déclassée en 1973 en D522.

Aménagements

• Suppression du passage à niveau de Bourgoin-Jallieu : 1982.
• Déviation Ouest de Bourgoin-Jallieu : 1988 au Nord-Ouest et 1992 à l'Ouest.

Description

• La RN522 comporte deux tronçons jouant deux rôles différents :
  • Au Nord de Bourgoin-Jallieu, elle fait partie de la liaison verte Bourgoin-Jallieu - Bourg-en-Bresse;
  • Au Sud de cette ville, elle fait partie de la liaison verte Bourgoin-Jallieu - Vienne.

• La partie Nord se déroule dans une plaine entourée de modestes collines. Elle prend naissance à Lancin, sur l'ex-RN75 par un simple carrefour à "Stop". A Sablonnières, elle croise l'ex-RN517 par un autre carrefour à "Stop", puis se dirige vers Bourgoin-Jallieu à travers une plaine marécageuse.
• A Bourgoin-Jallieu, le tracé d'origine correspond aux actuelles avenue de la Libération et rue de Stalingrad. Entre les deux, le tronc commun avec la RN6 empruntait les rues de la Liberté et de la République. Après 1970, le tracé passait dans le quartier Saint Michel, devant le stade, puis rejoignait la nouvelle RN6 par le boulevard Jean-Jacques Rousseau, juste avant la bifurcation de la RN85.
• La partie Sud est nettement plus sinueuse, car établie dans les collines des Terres Froides. De nombreuses sections sont limitées à 70 km/h. L'ascension est douce, mais continue de Maubec à Meyrieu-les-Étangs.
• A Saint-Jean-de-Bournay, elle rejoint l'ex-RN502 provenant de Champier, mais elle est prioritaire sur cette branche équipée d'un "Stop".
