Présentation

• À sa création le 16 décembre 1811, la Route impériale 99 est une route impériale française de III^e classe qui est définie comme la route de Roanne à Clermont. Elle joint à Chabreloche la route de Lyon à Bordeaux, n° 107.
• Un rapport daté du 8 floréal an XI (28 avril 1803) de l'Ingénieur-en-Chef des Ponts-et-Chaussées de la Loire indique qu'autrefois cette route faisait partie du grand itinéraire de La Rochelle à Lyon par Clermont et Roanne mais que, depuis l'ouverture de la route de Clermont à Lyon par Thiers et Feurs, elle était devenue beaucoup moins fréquentée du fait de la raideur de ses pentes et qu'elle ne servait plus guère qu'à la communication locale entre le Roannais et l'Auvergne.
• Lors de la renumérotation de 1824, elle est devenue la Route royale 81.
