Présentation

• La route nationale 341, ou RN341, est une ancienne route nationale française qui reliait Boulogne-sur-Mer à Arras dans le département du Pas-de-Calais (62).

Historique

• A sa création, en 1933, elle est définie comme la route d'Arras à Boulogne-sur-Mer.
• D'Arras à Sainte-Catherine, on empruntait la N25. De Saint-Martin-Boulogne à Boulogne-sur-Mer on empruntait la N42.
• La RN341 est issue du chemin de grande communication n° 52, ou Gc52 (62) pour le tronçon compris entre Arras et le lieu-dit Les Courteaux, à l'extrémité de la RN343 au Sud-Est de Desvres, et du chemin de grande communication n° 96, ou Gc96 (62) pour le tronçon compris entre Desvres et Boulogne-sur-Mer. Au droit de Desvres, l'itinéraire emprunte un chemin vicinal ordinaire de la commune de Longfossé et un embranchement du Gc96 pour éviter le passage par les rues étroites du centre-ville.
• Cette route suit en grande partie le tracé de la Chaussée Brunehaut entre Arras et Thérouanne. Cela peut expliquer la forte déclivité de la route en certains endroits même si des virages ont été aménagés par exemple à Amettes ou Gauchin-Légal. Des corrections de virages ont aussi été réalisées entre Desvres et Thérouanne.
• Sur ce tronçon, il avait été prévu au milieu des années 1930 que la RN341 soit partiellement intégrée au Grand Itinéraire de Calais à Vitry-le-François. L'aménagement sur les communes d'Estrée-Blanche, Rely, Ligny-lès-Aire, Saint-Hilaire, Auchy-au-Bois, Ames et Amettes a été déclaré d'utilité publique par un décret publié au Journal Officiel du 25 décembre 1936 et devait être financé au titre du plan de grands travaux contre le chômage. Il devait être accompagné d'une déviation d'Estrée-Blanche et d'un tracé neuf entre Pernes et Ourton. Aucun de ces projets n'a été exécuté.
• La RN341 a été déclassée en 1973, elle fut renumérotée en D341.
