Présentation

• La route nationale 686, ou RN686, est une ancienne route nationale française qui comprenait deux très courts tronçons : un de Riom à la N141 desservait Volvic, l'autre allait de Pontgibaud à Massagettes, vers Rochefort-Montagne.

Historique

Généralités

• A sa création, en 1933, elle est définie comme la route de Riom à Rochefort-Montagne.
• Le trajet de Massagettes à Rochefort-Montagne se faisait alors via la N89.
• Elle est issue du chemin vicinal de grande communication n° 22 du Puy-de-Dôme, ou Gc22 (63).
• A l'origine, elle partait de la RN685 à Riom (actuelle rue des Chaumettes) et n'atteignait donc pas la RN9. Cette anomalie est corrigée le 31 mai 1935, date à laquelle son tracé est prolongé de 200 mètres à l'occasion du changement de tracé de la RN685.
• Elle fut intégralement déclassée en 1973.

Aménagements

• Déviation de Volvic : 1975 au Sud-Ouest et 1976 au Sud-Est, échangeur avec la D15 et recalibrage en 2006.

Autour de la route

• Château de Tournoël.
• Thermes de Volvic.
