Présentation

• La route nationale 743, ou RN743, est une ancienne route nationale française qui reliait Parthenay à Niort.

Historique

• A sa création, en 1933, elle est définie comme la route de Parthenay à Niort.
• Entièrement située dans les Deux-Sèvres, elle est issue du chemin vicinal de grande communication n° 40, ou Gc40 (79), pour la section comprise entre Niort et Échiré, et du chemin vicinal de grande communication n° 2, ou Gc2 (79), pour la section comprise entre Échiré et Parthenay.
• Aux abords de Niort, cet axe récupère tardivement une petite partie du tracé de la route stratégique 9, déclassée en 1862.
• La RN743 est déclassée en 1973.
• Départementalisée, cette route est progressivement rectifiée et modernisée dans le cadre de l'aménagement d'un Axe Anjou - Poitou. Elle est désormais presque intégralement aménagée en 2+1 voies, ce qui fluidifie et sécurise les conditions de circulation. Son tracé n'a presque plus rien de commun avec celui d'origine (voir la carte en zoomant).
