Présentation

• La route nationale française 2171, ou RN2171, est une ancienne route nationale française qui correspondait à deux parcours très proches :
  • Liaison entre les deux tronçons de la RN171 au Nord-Est de Savenay. Cette route a été créée lors d'une première refonte de l'échangeur de Savenay pour assurer la continuité de la RN171 sur le parcours Rennes - Saint-Nazaire, alors que la priorité du trafic était donnée au parcours Nantes - Saint-Nazaire. Devenue une route de desserte locale après la seconde refonte de l'échangeur de Savenay en 1989, elle a été déclassée en 2007 et intégrée pour partie dans la D3 et pour partie dans les voiries communales de Savenay et La Chapelle-Noyal.
  • Traversée de Bouvron suite à la construction de la déviation de la RN171. D'un intérêt très local, cette route a été intégrée le 7 décembre 2020 dans la voirie communale.
