Présentation

• La route nationale 137^D, ou RN137^D, est une ancienne route nationale française, antenne de la RN137, qui a connu trois affectations :
  • Traverse intérieure de La Rochelle, en 1933.
  • Desserte du bac de Saint-Servan-sur-Mer, de 1933 à 1973.
  • Boulevard Périphérique Est de La Rochelle, de 1972 à 1978.

Historique

• A sa création, en 1933, la RN137^D est décrite comme étant l'annexe de la Rochelle (traverse intérieure). En réalité, il s'agit d'une erreur administrative très surprenante dans la mesure où cette annexe avait été déclassée en bonne et due forme par un décret du… 12 août 1925 ! Cette "traverse intérieure" correspondait au tracé historique de la RN137 dans le centre-ville de La Rochelle. Elle entrait par la Porte Saint-Nicolas, passait notamment par le quai Maubec et la rue des Fonderies, puis sortait des murs par la Porte Royale. Elle avait été dédoublée au XIX^e siècle par une "traverse extérieure" qui reprenait l'ancien chemin de Saint-Éloi à Tasdon et qui était devenue au fil des ans l'itinéraire principal.
• L'erreur administrative a été très rapidement corrigée et le numéro 137^D a été donné à l'annexe suivante, l'éphémère RN137^E. Cette annexe de Saint-Servan-sur-Mer assurait la continuité du réseau routier national entre les deux rives de la Rance, par le bac entre l'extrémité de la RN168, à la cale du Bec de la Vallée à Dinard, et la cale Solidor à Saint-Servan. Devenue inutile depuis l'arrêt du bac en 1966, elle a été déclassée en 1973.
• Enfin, le numéro a également été attribué à titre provisoire au Boulevard Périphérique Est de La Rochelle, de 1972 à 1978, date à laquelle il a été intégré à la RN137.
