Présentation

• La route nationale 448, ou RN448, est une ancienne route nationale française qui a connu plusieurs tracés en perdant des tronçons au cours des déclassements dans le réseau routier national.

Historique

Généralités

• A sa création, en 1933, elle est définie comme la route de Villeneuve-Saint-Georges à Argent-sur-Sauldre par Malesherbes.
• Le trajet de Villeneuve-Saint-Georges à Montgeron se faisait via la N5.
• Suite à la réforme de 1972, la RN448 fut réduite à son tracé dans la proche banlieue de Paris (de Montgeron à Corbeil-Essonnes).
• En 1978, le fascicule 78-11^Bis du 27 février prévoit qu'elle devienne la route d'Evry N446 à Evry A6. Mais elle n'est finalement pas déclassée de Montgeron à Corbeil-Essonnes et c'est donc le numéro N449 qui désigne ce tracé dès le rectificatif du 28 novembre (Circulaire 78-152).
• Le dernier tronçon fut déclassé en 2006.

Aménagements

• Aménagement à 4 voies entre Montgeron et Draveil : 1970.
• Modification de tracé dans Milly-la-Forêt : après la mise en service du contournement Nord vers 1985 et de la D142 (91) vers 1997, le tracé en centre ville est déclassé par le Département dans la voirie communale. La D448 est déviée par l'Est pour emprunter la partie Est de la déviation de Milly-la-Forêt et l'ancien tracé de la D142 (91).
