Présentation

• La route nationale 623, ou RN623, est une ancienne route nationale française qui reliait Castelnaudary (RN113) à Limoux (RN118), dans l'Aude (11).

Historique

• A sa création, en 1933, elle est définie comme la route de Castelnaudary à Limoux.
• Elle est issue du chemin vicinal de grande communication n° 9, ou Gc9 (11), à l'exception des deux premiers kilomètres à Castelnaudary qui appartenaient au chemin vicinal de grande communication n° 6, ou Gc6 (11).
• Suite à la réforme de 1972, la route a été déclassée en D623 sur l'intégralité de son parcours.

Alignements de platanes

• Les alignements de platanes le long de la D623 procurent de l'ombre aux voyageurs depuis plusieurs siècles. Ils sont né d'une volonté nationale d'embellir le paysage, d'assainir et de stabiliser la chaussée, ainsi que de délimiter l'espace publique (la route) de l'espace privé.

• Au début de l'année 2009, le Conseil Départemental de l'Aude a prévu d'abattre tous les platanes qui bordent la D623. Si la moitié des accidents sur cette route impliquent un arbre, dans l'autre moitié des accidents il n'y a pas d'arbre impliqué. De plus, l'abattage ouvre le champ visuel, ce qui a pour conséquence l'augmentation de la vitesse. La solution de l'abattage systématique n'est donc pas adapté au problème de sécurité routière ([1]).
