Présentation

• La route nationale 506, ou RN506, est une ancienne route nationale française dont le parcours s'est réduit au fil du temps jusqu'à disparaître complètement en 2006.

Historique

Généralités

• A sa création, en 1933, elle est définie comme la route de Bonneville à la frontière suisse par Chamonix.
• Elle est issue de la route départementale n° 4 de Haute-Savoie, ou RD4 (74), pour la section comprise entre Bonneville et Chamonix, et du chemin de grande communication n° 11, ou Gc11 (74), pour la section comprise entre Chamonix et la frontière suisse.
• Elle faisait tronc commun avec la RN202 entre Le Fayet et Cluses.
• On lui adjoint en 1965 une annexe, la RN506^A, pour l'accès au Tunnel du Mont-Blanc.
• En 1978 elle est réduite à la route de Chamonix N205 à la frontière suisse à Vallorcine.
• Son parcours est donc intégralement resté dans le réseau routier national mais a été récupéré en grande partie par la nouvelle RN205 entre Bonneville et Chamonix, lequel a été partiellement déclassé depuis en D1205.
• En 2006, la dernière section numérotée RN506 a été reversée dans le réseau routier départemental de la Haute-Savoie (74) et renumérotée en D1506.
