Présentation

• La route nationale 532, ou RN532, est une route nationale française reliant Valence à Bourg-de-Péage.
• Cette voie express sert de prolongement naturel à l'autoroute A49 dans sa connexion avec l'autoroute A7 à Valence.

Historique

Généralités

• Le premier tracé de la RN532 reprend celui des anciennes D3 dans l'Ardèche et dans la Drôme jusqu'à Bourg-de-Péage. Elle reprend l'ancien tracé du Gc61 dans l'Isère et celui du Gc6 dans la Drôme entre Bourg-de-Péage et Saint-Jean-en-Royans.
• La RN532 actuelle a bien peu de points communs avec les différents itinéraires qui ont porté le même numéro.
• A sa création, en 1933, elle est définie comme la route d'Yssingeaux à Grenoble par Tournon-sur-Rhône.
• Le trajet d'Yssingeaux à Saint-Bonnet-le-Froid se faisait alors via la N105. De Sassenage à Grenoble, on empruntait la N531.
• Jusqu'en 1958, on traversait le Rhône entre Tournon-sur-Rhône et Tain-l'Hermitage par le vieux pont suspendu construit par Marc Seguin en 1849 (plus ancien pont suspendu encore en service en France, classé monument historique depuis 1985). Après la mise en service du nouveau pont Gustave Toursier, l'ancien ouvrage a été transformé en passerelle réservée aux piétons et cyclistes et déclassé dans la voirie départementale en tant que CD219 (07).
• Lors de la réforme de 1972, une nouvelle RN532 a été dessinée pour relier directement Saint-Péray et Valence à Grenoble, via la vallée de l'Isère. Les anciens tronçons ont été renumérotés en D532, à l'exception de liaison entre l'A7 et la RN86 à Tain-l'Hermitage et Tournon, incluant la traversée du Rhône, récupérée par la nouvelle RN95. La courte section du tracé d'avant 1972 entre l'Avenue Berthelot et le Pont Vieux à Romans-sur-Isère est numérotée actuellement D92.
• La nouvelle RN532, route de Saint-Péray N86 à Grenoble N75, s'est appuyée sur les anciennes nationales suivantes :
  • N533 de Saint-Péray à Valence.
  • N92 de Valence à Bourg-de-Péage.
  • N531 de Bourg-de-Péage à Saint-Just-de-Claix.
  • N532 de Saint-Just-de-Claix à Sassenage.
  • N531 de Sassenage à Fontaine.
  • N90^D de Fontaine à Grenoble.
• A partir de 1983, on adjoint à la RN532 une annexe, la RN1532, qui contournait Valence par l'Est jusqu'en 2002, date de son absorption par la RN7.
• La réforme de 2005 a été fatale à cet itinéraire qui dédoublait à la fois la RN92 et surtout l'A49 dans la Vallée de l'Isère. Seule la voie express reliant Valence à Bourg-de-Péage a été conservée dans le Réseau routier national alors que le restant de l'itinéraire était renuméroté en D532 dans la Drôme (26) et en D1532 dans l'Isère (38).

Aménagements

• Créneau entre Valence et Saint-Marcel-lès-Valence : 1975.
• Déviation de Chanos-Curson : 25 juillet 2011.

Futur

• A long terme, il est envisagé, soit une mise aux normes autoroutières de la RN532, soit la création d'un grand contournement de l'agglomération valentinoise.

Autour de la route

• Montagne ardéchoise.
• Le Mastrou à Tournon-sur-Rhône.
• Valence.
• Parc Naturel Régional du Vercors.
• Grenoble.
