Présentation

• La route départementale D971 (50), ou RD971 (50), est une route départementale de la Manche (50) qui relie la D973 (ex-RN173), sur la commune de Saint-Pair-sur-Mer, à la RN13, sur la commune nouvelle de Carentan-les-Marais.
• Elle correspond en grande partie au tracé de la RN171 déclassée en 1973. Les portions créées plus récemment ont été attribuées à la D973 pour assurer la continuité, bien que n'ayant jamais été classées dans la voirie nationale.
• Les contournements de Granville et Coutances présentent actuellement des caractéristiques de voie express.
• Elle possède plusieurs annexes, dont la plupart correspondent au tracé originel de la RN171 et ont porté le numéro D973 entre le déclassement de 1973 et l'ouverture de leurs déviations respectives :
  • la D971^E1 dessert Orval (commune nouvelle d'Orval sur Sienne) ;
  • la D971^E2 correspond à la Rue Paul Poirier à Granville ;
  • la D971^E3 correspond au tracé originel de la RN171 dans la traversée de Coutances ;
  • la D971^E5 correspond au tracé originel de la RN171 entre Granville et Bréville-sur-Mer ;
  • la D971^E6 correspond au tracé originel de la RN171 dans la traversée de Bréhal ;
  • la D971^E9 correspond au tracé originel de la RN171 dans la traversée de Carentan.
