Présentation

• La route départementale D48 (95), ou RD48 (95), est une route départementale du Val-d'Oise (95) qui relie Argenteuil à Conflans-Sainte-Honorine dans les Yvelines (78).

Généralités

• Cette route offre un second itinéraire complémentaire à la D392 entre Argenteuil et Cormeilles-en-Parisis, tout en passant au plus près de leurs centres-villes. Dans ce même cadre, elle constitue un rôle majeur dans la desserte Ouest-Est d'Herblay.
• La route effectue ensuite une courte incursion dans les Yvelines (78) et joint Conflans-Sainte-Honorine. Son parcours se poursuit à l'aide d'une section de la D48 (78), de la D54 (78) et de plusieurs voies communales à sens unique, nuisibles à la lisibilité de l'itinéraire.
• Elle retrouve ensuite le Val-d'Oise (95) à l'aide de son annexe numérotée D48^E en direction d'Éragny-sur-Oise et de Neuville-sur-Oise.
