Présentation

• La route départementale D31 (21), ou RD31 (21), est une route départementale de la Côte-d'Or (21) qui relie Semezanges au Jura à hauteur de Champvans.
• Elle a la particularité d'être extrêmement morcelée, car elle emprunte beaucoup de troncs communs.
• Depuis le 1^er juin 2020, la partie de cette route qui se situe dans le périmètre de Dijon Métropole a été reclassée en tant que route métropolitaine en conservant son ancien numéro, soit M31.

Historique

De nombreuses plaques Michelin à Gevrey
© Polo

• Il s'agit probablement de la route de Sombernon à Dôle par Gevrey.
• Ce chemin porte ce numéro depuis l'origine, entre Semezanges et Varanges. Vers 1920, l'ancien Gc16 (Soirans-Dole) lui fut ajouté.
• Il possédait une annexe, le Gc31^A, qui est devenu D31^A.
• On lui a adjoint quelques chemins vicinaux. La liste complète des annexes est donc :
  • La D31^A crée une liaison vers Quémigny-Poisot.
  • La D31^B va de Mailly-le-Château à La Chapelle.
  • La D31^C / M31^C correspond à un délaissé de l'ex-RN468, qui relie Thorey-en-Plaine à Époisses (Bretenière).
  • La carte Michelin fait part d'une autre annexe de la D31 de La Bussière à Flagey-lès-Auxonne, mais il pourrait s'agir d'une erreur.
  • La D931 / M931 lui a enfin été adjointe entre Gevrey-Chambertin et Perrigny-lès-Dijon.
