Présentation

• La route nationale 1 (974), ou RN1 (974), est une route nationale, qui assure la liaison entre Saint-Denis, la préfecture de l'île de la Réunion, et Saint-Pierre, l'une des sous-préfectures située au sud de l'île. Cette liaison s'effectue par l'ouest de l'île en passant par Saint-Paul, l'une des sous-préfectures de l'île de la Réunion.
• A sa création, en 1951, elle est définie comme l'itinéraire Saint-Denis à Saint-Pierre par Saint-Paul, Avirons et Saint-Louis, à l'exclusion de la bretelle passant par Étang-Salé-les-Bains. Elle est aussi connue comme la route de Saint-Denis à Saint-Pierre par l'Ouest. Elle succède donc à la route royale n° 1.
• Lorsque la Route du littoral est fermée à la circulation, les usagers doivent emprunter la D41 pour rallier La Possession.
• Cette RN est l'un des axes majeurs, mais elle ne fait plus partie du plan national routier de la Réunion.
• Elle possède officiellement le statut de voie express (route pour automobile) entre l'échangeur de Savannah à Saint-Paul et l'échangeur de l'Etang-Salé à l'Etang-Salé, même si plusieurs autres sections possèdent des caractéristiques proches d'une voie rapide.
• Elle a été transférée au Conseil Régional de la Réunion dans son intégralité suite à la réforme de 2005 (à ne pas confondre avec la N1 métropolitaine). Mais elle a conservé son numéro ainsi que son cartouche rouge sur les panneaux routiers.

Historique

• La route littorale entre Saint-Denis et La Possession a été ouverte à la circulation le 1^er mai 1963 après 4 années de travaux (classement le 23/04/1963). Elle est portée à 2x2 voies le 5 mars 1976.
• Les RN2001 et RN1^A correspondent à l'ancien tracé de la RN1, où des agglomérations ont étés déviés par un tronçon de voie express.
