Autoroute 84

L'A84 dans le schéma national des autoroutes.

L'Autoroute 84, communément appelée « A84 », est une autoroute liée au département de la Manche.

Elle relie Caen (Calvados) à Rennes (Ille-et-Vilaine), en traversant le sud du département par Torigni-sur-Vire, Villedieu-les-Poêles, Avranches et Saint-James.

Elle porte également le nom d'E401 entre Pontaubault et le périphérique de Caen.

Elle constitue une partie de l'Autoroute des estuaires, qui, à terme, doit relier la Belgique à l'Espagne, en évitant Paris.

Décidée en 1979, elle est mise en service sur la quasi totalité de son parcours le 27 janvier 2003. Seul le contournement est d'Avranches reste à faire.

Le premier coup de pelle est donné en octobre 1995 sous la conduite de Bernard Tricoche, ingénieur de la Direction départementale de l'Équipement (DDE).

L'autoroute A84 est gratuite sur toute sa longueur.
