Présentation

• La route nationale 20^A, ou RN20^A, est une ancienne route nationale française, antenne de la RN20, qui a connu deux affectations:
• En 1933, elle est définie comme étant l'annexe de Pierre-Buffière et correspondait probablement à un franchissement de voie ferrée dans ce village de la Haute-Vienne (87). Elle a, semble-t-il, rapidement été déclassée.
• Puis on retrouve cette dénomination avant 1973 correspondant à l'ancienne traverse d'Orléans par la RN20. Dans les années 1960 et 1970, Orléans fait en effet l'objet de travaux pour assurer son contournement. A la veille de la réforme de 1972, le contournement Sud-Ouest de la ville par la RN20 est bouclé et l'ancien tracé est renommé RN20^A. C'est logiquement que cet axe urbain est alors déclassé et renommé en D920, elle-même déclassée en 1998 dans la voirie communale d'Orléans, entre la place Gambetta et l'avenue Roger Secrétain.

Autour de la route
