Présentation

• La route nationale 164^Bis, ou RN164^Bis, est une ancienne route nationale française qui reliait Montauban-de-Bretagne à Rostrenen.

Historique

Généralités

• A sa création, le 14 mai 1837, elle est définie comme la route de Rennes à Brest.
• En 1962, son tracé est déclassé entre Saint-Méen-le-Grand et Rennes au profit d'un nouvel itinéraire orienté sur Montauban-de-Bretagne et la RN12. Le raccordement direct sur la voie express est inauguré à la fin de l'année 1972.
• L'ancien tracé est alors intégré à la D125. Depuis le 1^er janvier 2017, la section située sur le territoire de Rennes Métropole a été reclassée en tant que route métropolitaine en conservant son ancienne dénomination, soit M125.
• En 1978, le tracé de la RN164^Bis est intégré à la nouvelle RN164.
