Route nationale 175

La route nationale 175 est une voie de la Manche dans sa partie entre sa frontière avec le Calvados et sa frontière avec l'Ille-et-Vilaine.

Sur sa longueur totale (304 km), elle relie Rouen (Seine-Maritime) à Rennes (Ille-et-Vilaine).

Elle est déclassée en D 975 entre la frontière avec l'Ille-et-Vilaine et Pontorson et en D 76 entre Pontorson. Elle passe ensuite à Précey et Avranches par son contournement à l'ouest (km 75), Sainte-Pience (km 87) et Villedieu-les-Poêles (km 97), puis le Calvados.

Histoire

Créée en 1824, à la suite de la Route impériale 195, elle est dénommée comme la route de Caen (Calvados) à Granville. Elle est reliée alors à la route n° 173 qui va de Granville à Avranches.

En 1839, la création de la RN 24bis la prive du tronçon compris entre Villedieu-les-Poêles et Granville.

Avant le déclassement de 1972, elle reliait seulement Villedieu-les-Poêles à Caen (Calvados).
