Présentation

• La route nationale 7, ou RN7, est une route nationale luxembourgeoise qui relie Luxembourg-Ville à la frontière belge à Schmiede en direction de Stavelot et de Vielsalm. C'est un axe majeur qui relie le Nord au Sud. Elle est la troisième route la plus longue du Luxembourg.
• Depuis les années 1960, cet axe fait l'objet de nombreux aménagements pour fluidifier le trafic avec la rectification des virages, la création de créneaux de dépassement au nord de Diekirch, ainsi que la construction de l'autoroute A7 et de la voie express B7 entre Luxembourg-Ville et Diekirch.

Historique

Généralités

• À sa création, en 1843, elle est décrite comme étant la route de Luxembourg à Diekirch, par Cruchten. Surnommée la « Route de Diekirch », elle succède alors à la Grande route belge de deuxième classe allant de Luxembourg vers Diekirch.
• La loi du 5 mai 1958 classe divers axes. La partie allant de Diekirch à la frontière belge en direction de Stavelot est issue de l'ancienne RN16, déclassée en 1958, tandis que le Boulevard Royal à Luxembourg-Ville est issu d'un ancien chemin repris. Dans la traversée à sens unique d'Ettelbruck, la RN7 reprend le tracé de l'ancienne RN7B.
• Jusque dans les années 1940, la RN7 constituait la route allant de Luxembourg à Diekirch, en passant par Cruchten. Elle passe depuis par le Rost, se substituant à l'ancienne RN26.

• 1850 : redressement de la côte d'Eich (Mémorial A72/1850)
• 1910 : construction d'un nouveau pont sur l'Alzette à Walferdange (Mémorial A68/1910)

• Années 1960 :
  • nouveaux ponts sur l'Alzette à Mersch, à Colmar-Pont.
  • réaménagement de la RN7 entre Ettelbruck et Ingeldorf, avec suppression du passage à niveau.
• Années 1970 :
