Présentation

• La route départementale D178, ou D178, est une route départementale française de Saône-et-Loire (71) qui relie actuellement Simard, sur la D678, à Ratte, sur la D140.
• Avant 1978, elle se prolongeait jusqu'à Thurey, sur l'ex-RN477.

Historique

• Il s'agit de l'ancien chemin vicinal d'intérêt commun n° 78, ou Ic78, classé dans la voirie départementale de Saône-et-Loire (71) le 27 janvier 1974.
• En cohérence avec la nomenclature utilisée par le département, cette route ne possède aucune annexe.
• En 1978, elle cède la portion de son tracé comprise entre Thurey et Simard au nouveau tracé de la RN78 entre Saint-Marcel et Louhans. Cette dernière route est déclassée en 2006 et est renumérotée en D678. Il est à noter que bien que cette cession soit depuis longtemps effective, la D178 débute toujours autour du point repère (PR) 5 à Simard.
