Présentation

• La route nationale 343, ou RN343, est une ancienne route nationale française qui reliait Saint-Pol-sur-Ternoise à Desvres dans le département du Pas-de-Calais (62).

Historique

• A sa création, en 1933, elle est définie comme la route de Saint-Pol-sur-Ternoise à Boulogne-sur-Mer.
• Le trajet de Desvres à Boulogne-sur-Mer se faisait via la N341.
• Elle est issue du chemin de grande communication n° 96 du Pas-de-Calais, ou Gc96 (62).
• Son origine à Saint-Pol-sur-Ternoise est décalée d'une centaine de mètres le 23 mars 1971, à l'occasion du classement du nouveau tracé de la RN39. Ce tronçon de la rue d'Hesdin, autrefois rue du Hamel, a la particularité d'avoir appartenu successivement à la RN16 jusqu'en 1877, à la RN39 jusqu'en 1971, puis à la RN343 jusqu'en 1974 avant d'être déclassé de la voirie nationale.
• La RN343 a été déclassée en 1974 et elle fut alors renumérotée en D343.
