Présentation

• La route nationale 166, ou RN166, est une route nationale française, classée en voie express, qui relie actuellement Ploërmel à Vannes.

Historique

Généralités

• A sa création, en 1824, elle est définie comme la route de Vannes à Dinan. Elle succède alors à la Route impériale 186.
• En 1933, elle est prolongée jusqu'à Dinard et elle devient la route de Vannes à Dinard. On lui adjoint alors une annexe, la N166^A.
• L'extrémité de la route à Dinan a évolué plusieurs fois entre 1824 et 1933. A l'origine, elle aboutissait intra-muros, sur l'ancien tracé de la route d'Avranches à Lamballe qui passait par les rues du Jerzual et de la Lainerie. En 1847, à la suite de la mise en service de la nouvelle route entre Le Pont-Ruffier et Dinan, l'extrémité est fixée à Cassepot, à 2 kilomètres à l'Ouest de Dinan, sur le nouveau tracé de la RN176. Le tronc commun entre Cassepot et Dinan était alors rattaché à la RN176, malgré le fait que celle-ci avait un numéro plus élevé, probablement pour des raison de continuité de l'axe Caen - Lamballe. La situation change au 1^er janvier 1890, avec le rattachement du tronc commun à la RN166 sur 2.140 mètres, de Cassepot à la Place du Champ. Le dernier changement est intervenu à l'occasion de la réforme de 1933, avec le prolongement de la RN166 vers Dinard à partir de la Place Duclos, par classement d'un petit tronçon du Gc2 à Dinan et du Gc12. Le court tronçon de 450 mètres entre la Place Duclos et la Place du Champ est alors restitué à la RN176.
• L'origine de la route à Vannes est décalée d'une centaine de mètres par arrêté ministériel du 6 mars 1964, à la suite de la mise en service de la déviation de la RN165.
• A l'origine, la RN166 traversait donc la Bretagne du Nord au Sud, de Dinard à Vannes, via Dinan et Ploërmel. Le tronçon Dinard - Ploërmel a été déclassé suite à la réforme de 1972.
• Elle devient ainsi la route de Vannes, N. 165, à Ploërmel, N. 24.
