Présentation[]
- A sa création le 16 décembre 1811, la Route impériale 198 est une route impériale française de IIIe classe qui est définie comme la route de Caen aux Sables-d'Olonne, par Nantes . Elle s'embranche à Fougères sur la route précédente, de Caen à Granville, et va joindre, à Lamotte-Achard, celle de Saumur aux Sables-d'Olonne, n° 180.
- Lors de la renumérotation de 1824, elle est devenue la Route royale 178.
