Historique

Plaque Dunlop

Généralités

• A sa création en 1824, elle est décrite comme étant la route de Valenciennes à Maubeuge et à Philippeville. Elle s'embranche à Jalin, sur la route n° 45, de Marle à Valenciennes. Elle succède alors à la Route impériale 52.
• Le 16/08/1843, une lettre du sous-secrétaire d’État aux travaux publics reconnaît l'existence d'une erreur dans le classement de 1824. En effet, la courte section desservant Givet après un long passage en Belgique qui faisait initialement partie de la route impériale 52 n'était pas mentionnée dans la nouvelle nomenclature alors qu'elle devait logiquement rester classée dans la voirie nationale. Dès cette date, on rend à la RN49 la partie desservant Givet et la route est prolongée au-delà de Philippeville dans la partie belge. Elle devient route de Valenciennes à Luxembourg.
• En 1933, on lui adjoint une annexe, la N49^A.
• En 1973 est déclassé le court tronçon ardennais (renuméroté en D949) tandis qu'en 1978 est classée la nouvelle voie express à l'Est de Maubeuge en remplacement de l'ancien tracé situé plus au Sud (renuméroté en D936).
• A l'ouest, en 1978, la RN49 fut prolongée jusqu'à Lille en récupérant divers tronçons appartenant auparavant à d'autres routes : la RN25 de Lille à Seclin, la RN353 entre Seclin et Nouveau-Jeu, la nouvelle liaison en direction de Raismes constituée par les RN353^A et RN353^B et enfin un tronçon de la RN45 jusqu'à Valenciennes et Jenlain.
• Elle devient ainsi la route de Lille, A. 25, à la frontière belge, à Jeumont.
• Cependant, l'achèvement de l'A23 au début des années 1980, longeant ou se substituant à l'ancienne RN entre Orchies et Valenciennes entraîna le déclassement rapide de ce tronçon nouvellement créé, en D549 et D953 ! Depuis le 1^er janvier 2017, l'exploitation de cette dernière section est assurée par la Métropole européenne de Lille entre Lille et Seclin. En conséquence, elle devenue une route métropolitaine sous l'appellation M549, les cartouches ayant été changés sur le terrain en 2018.
• De même, l'établissement progressif de la voie express entre Valenciennes et Maubeuge fut suivie du déclassement de l'ancienne route qui traversait les agglomérations sur le parcours.
• La réforme de 2005 retrancha presque complètement cet axe du réseau routier national.
• Aujourd'hui, seul un tronçon de quelques kilomètres subsiste afin de relier les deux tronçons de la RN2 à hauteur de Maubeuge, en attendant la concrétisation du projet de contournement Nord-Ouest.
