Présentation

• La route nationale 149, ou RN149, est une route nationale française qui relie actuellement Migné-Auxances (Poitiers) à Brétignolles (79).
• Maillon occidental de la Route Centre-Europe-Atlantique, elle est appelée à devenir rapidement une voie express sur l'intégralité de son parcours.
• L'achèvement des travaux de la RN249 entre Bressuire et Cholet a entraîné le déclassement de la RN149 qui lui est parallèle, avec un transfert effectif en décembre 2010.

Historique

• A sa création, en 1824, elle est décrite comme étant la route de Fontenay aux Sables-d'Olonne. Elle s'embranche sur la route précédente, de Limoges à Nantes, à la sortie de la ville de Fontenay. Elle succède alors à la Route impériale 169.
• Cet itinéraire historique a été déclassé consécutivement à la réforme de 1972. Il a fait par la suite l'objet de lourds travaux, avec la construction de déviations à Luçon, Talmont-Saint-Hilaire et aux Sables-d'Olonne.
• En 1978, elle devient route de Poitiers, N. 147, à Nantes, N. 137 N. 23.
• La RN149 actuelle est l'héritière directe de l'ancienne RN148^Bis qui reliait Nantes à Poitiers avant 1973.
• La mise en voie express progressive de l'axe entre Nantes et Cholet, via la nouvelle RN249, a condamné l'itinéraire parallèle de la RN149 entre Nantes et Mortagne-sur-Sèvre qui a été intégralement déclassé en 2005 et depuis le 1^er décembre 2010 entre Mortagne-sur-Sèvre et Brétignolles.
