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).

Le 29 mars [[1999], un tronçon de 48 km entre Avranches et Saint-Aubin-du-Cormier (Ille-et-Vilaine) est inauguré .

L'autoroute A84 est gratuite sur toute sa longueur.
