Présentation

• La route nationale 781, ou RN781, est une ancienne route nationale française qui reliait Hennebont à Locmariaquer.
• Elle suivait le littoral de Port-Louis à Locmariaquer, à l'extrémité de la presque'île ouest du golfe du Morbihan. Elle se terminait à environ 2 km à vol d'oiseau de la RN780 qui parcourait la presqu'île opposée.

Historique

• À sa création en 1933, elle est décrite comme la route d'Hennebont à Locmariaquer par Port-Louis.
• Entièrement située dans le département du Morbihan, elle est issue du chemin de grande communication n° 36, ou Gc36 (56), pour la section comprise entre la RN24 à Hennebont et Port-Louis, du chemin de grande communication n° 33, ou Gc33 (56), pour la section comprise entre Port-Louis et Riantec, du chemin de grande communication n° 22, ou Gc22 (56), pour la section comprise entre Riantec et Kervernic, et du chemin de grande communication n° 20, ou Gc20 (56), pour la section comprise entre Kervernic et Locmariaquer.
• Son origine à Hennebont est décalée de quelques dizaines de mètres le 17 juillet 1955, à l'occasion du changement de tracé de la RN24 dans le cadre de la reconstruction de la ville.
• Le Pont Lorois, sur la ria d'Étel, est détruit le 4 novembre 1944 dans le cadre des combats pour réduire la poche de Lorient. Il n'est remis en service que 12 ans plus tard, le 13 septembre 1956.
• En 1973, la RN781 a été déclassée en D781 dans le Morbihan (56).
