Présentation

• La Route impériale 12 était une route impériale française de 1^re classe qui reliait Poitiers à Rochefort via Niort. Rochefort était à l'époque un important arsenal militaire qui n'était pas directement desservie depuis Paris par la Route impériale 11. Une antenne a donc été instaurée pour longer la côte.
• Après la chute de l'Empire, la Route impériale 12 est devenue la Route nationale 11.
• Les réformes de 1973 et 2006 ont provoqué le déclassement de cet axe entre Mauzé-sur-le-Mignon et Rochefort puis entre Poitiers et Frontenay-Rohan-Rohan. La courte section subsistante est appelée à devenir l'Autoroute A810.
