Présentation

• La route nationale 180, ou RN180, est une ancienne route nationale française qui reliait Honfleur à La Maison-Brûlée.

Historique

Généralités

• A sa création, en 1824, elle est définie comme la route d'Honfleur à Rouen. Elle rencontre, à la Bouille, la route n° 138, de Bordeaux à Rouen. Elle succède à la Route impériale 200.
• Une grande partie de son parcours (Saint-Maclou - La Maison Brûlée) fut reprise par la nouvelle N175 en 1978 tandis que le reste de l'itinéraire était déclassé en D180 et D580.
• On notera que la RN180 a possédé de façon très éphémère avant 1933 deux annexes : les N180^A et N180^B.
• La déviation de La Rivière-Saint-Sauveur a pris les noms de D180/D580 après avoir dans un premier temps été numérotée D580^Bis. Le tracé originel de la RN180 a en conséquence été renuméroté D180^E/D580^A entre Fiquefleur et Honfleur.
