Présentation

• La route nationale 798, ou RN798, est une ancienne route nationale française qui reliait Laval à Pontaubault.

Historique

Généralités

• À sa création, en 1933, elle est décrite comme la route de Laval à Avranches par Fougères.
• De Pontaubault à Avranches, le trajet était commun avec la RN176.
• Dans la Mayenne, elle est issue de la route départementale n° 8, ou RD8 (53), pour la section comprise entre Laval et Les Chênes Secs, et de la route départementale n° 12, ou RD12 (53), pour la section comprise entre Les Chênes Secs et la limite de l'Ille-et-Vilaine. En Ille-et-Vilaine, elle est issue du chemin de grande communication n° 104, ou Gc104 (35). Dans la Manche, elle est issue du chemin de grande communication n° 12, ou Gc12 (50).
• Cet axe récupère tardivement une partie du tracé de la route stratégique 20, déclassée en 1862.
• En 1973, elle a été déclassée en D30 et D31 dans le département de la Mayenne (53), en D798 dans le département de Ille-et-Vilaine (35) et en D998 dans le département de la Manche (50).
