Présentation

• La route nationale 11, ou RN11, est une route nationale française qui a connu plusieurs affectations au gré des déclassements et reclassements dans le réseau routier national.
• Elle appartient à la RCEA.

Historique

Généralités

• A sa création, en 1824, elle est définie comme étant la route de Paris à Rochefort. Elle s'embranche à Croutelle, près Poitiers sur la route précédente n° 10. Elle succède alors à la route impériale 12.
• La RN11 reliait donc initialement Fontaine-le-Comte (au Sud de Poitiers) à Rochefort.
• Son tracé terminal entre Mauzé et Rochefort est déclassé en 1973 et la route est réorientée de Mauzé sur La Rochelle. Ce tracé est officiellement repris à la RN22 en 1978 et le nouvel itinéraire devient donc la route de Poitiers N. 10, à La Pallice.
• Par la suite, elle commence à être aménagée en voie express, notamment entre Niort et La Rochelle.
• En 1999, suite au bouclage de la Rocade Est de Niort, l'ancien tracé à l'Ouest de la ville est partagé entre la RN148 au Nord et la RN2011 à l'Ouest.
• De même, le bouclage du Boulevard Périphérique de La Rochelle entraîne le reclassement du tracé terminal de la RN11 en RN2011.
• Par décret du 7 août 2002, la RN11 est devenue administrativement l'autoroute A810 entre Épannes et La Rochelle. Dans les faits, les travaux de mise aux normes autoroutières n'ont jamais été engagés faute de financement. Ils visaient en particulier à doubler cet axe fréquenté et accidentogène sur la déviation de Mauzé-sur-le-Mignon.
• A partir de 2006, ne subsiste plus que le tracé d’Épannes à La Rochelle.

Construction

• Rectification à l'Est de Saint-Maixent-l'École : 1840 (parachèvement en 1841).
• Abords et traversée de la Place de la Brêche à Niort : 1859.

Aménagements

• Déviation de Lusignan : 1976 au Sud-Ouest (inclut la suppression d'un passage à niveau), 1982 au Sud et 1993 au Sud-Est, vraisemblablement sous Maîtrise d'Ouvrage départementale. Face à l'inaction de l’État qui ne considérait pas qu'une déviation sur une route nationale parallèle à une autoroute concédée soit prioritaire et qui refusait donc d'inscrire ce contournement dans le Contrat de Plan, les collectivités locales ont assumé la fin de l'aménagement, l'État ne finançant que 30 % du montant hors taxes des travaux.
• Suppression du passage à niveau de La Potière : mai 2003.
• Section au Nord-Est de Niort : doublée en juillet 1973 et en 1974. Voir l'article sur la Rocade de Niort.
• Déviation de Surgères : voir D911^Bis et D939^Bis.
• Déviation de Muron : 1995.

Futur

• Partie déclassée : élargissement à 2+1 voies entre Fontaine-le-Comte et Coulombiers en projet.
