Présentation

• La route nationale 445, ou RN445, est une ancienne route nationale française qui a connu deux affectations distinctes au cours du temps :
  • À partir de 1933, elle reliait Lormes, sur l'ex-RN444, à Châtillon-en-Bazois, sur l'ex-RN78. Cet axe secondaire entièrement situé dans la Nièvre (58) fut déclassé en 1973 en D945.
  • Le numéro laissé vacant fut réattribué en 1978 à un barreau reliant Viry-Châtillon, sur l'ex-RN7, à Fleury-Mérogis, sur la RN104 (Francilienne). Cet itinéraire est déclassé en 2006 en D445.

Historique

Généralités

• À sa création, en 1933, elle est définie comme la route de Lormes à Châtillon-en-Bazois.
• Elle est issue du chemin de grande communication n° 32, ou Gc32, de la Nièvre (58).
• Elle possède un tronc commun avec l'ex-RN485, entre Epiry et Aunay-en-Bazois, et constitue ainsi une courte section de la Route Buissonnière.
• Cet axe parfaitement secondaire et peu fréquenté est logiquement déclassé en 1973 et est renuméroté en D945.
• En 1978, le numéro est récupéré pour désigner une section de la D29 entre Viry-Châtillon, sur l'ex-RN7, et Évry, sur la RN446 (à l'époque voie primaire S2, devenue aujourd'hui la Francilienne) à Fleury-Mérogis), classée dans la voirie nationale par un arrêté publié le 28 septembre 1978. La RN445 est alors redéfinie comme la route d'Évry, N. 446, à Viry-Châtillon, N. 7, et est déclassée en 2006 en D445.

Aménagements

• L'itinéraire entre Évry et Fleury-Mérogis reprend en grande partie une route pré-existante doublée en 1972.
• Le prolongement de cet itinéraire jusqu'à la Francilienne est mis en service la même année.
