Modifications : Route nationale française 24

Version du 11 novembre 2012 à 16:07

Présentation

La route nationale 24, ou RN24, est une route nationale française qui a conservé son parcours depuis l'époque napoléonienne. Considérée à l'origine comme un embranchement de la RN12 de Rennes à Lorient, la RN24 est ainsi une des plus courtes nationales radiales du réseau routier national.
A sa création, en 1824, elle est décrite comme étant la route de Paris à Lorient. Elle s'embranche à la sortie de la ville de Rennes, sur la route N°12, de Paris à Brest. Elle succède alors à la route impériale 27.
En 1978, la RN24 est définie de façon plus concise comme la route de Rennes, N. 12, à Lorient.
Intégrée dans le Plan routier breton, la RN24 a fait l'objet d'un aménagement intégral en voie express jusqu'aux portes de Rennes achevé en 1994. Sur la majeure partie de son parcours, la nouvelle route recouvre ainsi le tracé historique.

Futur

Désengorgement de l'entrée de Rennes qui passe actuellement en pleine zone industrielle. Les carrefours à feux génèrent quotidiennement de nombreux bouchons. Un projet de barreau au Sud de Vezin-le-Coquet permettrait à la RN24 de rejoindre directement la RN12 et la Rocade de Rennes. Sujette à de fortes oppositions, sa réalisation a été différée à plusieurs reprises mais reste à l'étude.
Complément de la jonction RN24 - RN165 à l'Est de Lorient.
