Présentation

• La route nationale 327, ou RN327, est une route nationale française qui a connu deux parcours radicalement différents dans le réseau routier national.

Historique

Généralités

• A sa création, en 1933, elle est définie comme la route de Versailles à Beauvais par Pontoise. Le parcours de Versailles à Pontoise se faisait alors via la N184, et d'Allonne à Beauvais, on empruntait la N1.
• Elle a repris en Seine-et-Oise (actuel Val-d'Oise (95)) le Gc79 de Pontoise à Hérouville puis le Gc72 d'Hérouville à la limite du département. Dans l'Oise (60), elle a repris l'intégralité du Gc135 (ancienne route départementale n° 5).
• Elle est intégralement déclassée en 1973.
• Le numéro est alors récupéré par un court barreau faisant la liaison entre Menton et l'Italie, anciennement numéroté en N7^H.
• Il s'agit de la route de Menton, N. 7, à la frontière italienne (Menton).
• Elle est déclassée en 2006.

Aménagements

• Déviation d'Ennery : 5 février 1999. L'ancien tracé devient la D927^Z (95), puis est déclassé dans la voirie communale.
• Rectification à l'Ouest d'Hérouville : 1936, supprimée avec la création d'un carrefour giratoire en 1997.
• Déviation de Méru : 1976.
• Déviation de Corbeil-Cerf : 1988.
• Rectification des virages au Bois de Molle : 1985 (virage Sud) et 1990 (virage Nord). En 1994, afin de permettre la construction de l'A16, le premier virage cité est finalement démoli (et reconverti en passage à faune), en échange d'une déviation du Bois du Molle par l'Ouest.
• Giratoire de Saint-Quentin à Auteuil : 1994.

Autour de la route

• La Côte d'Azur
• La cathédrale de Beauvais
