Présentation[]
- La route départementale D18 (42), ou RD18 (42), est une route départementale de la Loire (42) qui relie la D353 dans le département de Saône-et-Loire (71) à la D16, près de Virigneux.
- Son tracé est assez particulier car elle possède de nombreux troncs communs, parfois assez longs.
Historique[]
- Elle est issue de l'ancien Gc18.
- Son tracé originel a été rectifié entre Lentigny et Saint-Polgues : historiquement elle continuait tout droit après Lentigny, et empruntait une partie des actuelles D203 et D202, puis montait vers les hameaux de Paimpillot et Vitré, avant de redescendre vers Saint-Polgues. La portion entre Le Ménard et Saint-Polgues a par la suite été cédée à la D8 avant d'être déclassée.
- Elle possédait une annexe : la D18A qui desservait la commune de Saint-Jean-Saint-Maurice-sur-Loire. Elle est aujourd'hui en partie déclassée ou réattribuée à la D203.
Description du tracé[]
- La D18 débute à l'extrême nord du département de la Loire, dans le prolongement de la D353 (71).
- Elle part vers le sud et traverse Vivans.
- Elle croise la N7 à Saint-Germain-l'Espinasse, où elle emprunte une portion du tracé originel de cette dernière.
- Elle traverse Pouilly-les-Nonains, Ouches, Lentigny, puis arrive à Villerest, où elle passe sur le barrage du même nom, construit en 1984, faisant ainsi monter les eaux des gorges de la Loire pour former le Lac de Villerest.
- Après 2 km elle est interrompue par la D43.
- S'en suit alors un long tronc commun avec plusieurs routes (D43, D45, D56, puis de nouveau D45) jusqu'à Saint-Polgues où elle effectue une petite boucle autour du village, puis reprend en direction du sud.
- Elle traverse ensuite Souternon, passe au dessus de l'A89, puis est interrompue par la D1 à Saint-Julien-d'Oddes.
- Elle reprend sur la D8 au sud de Saint-Germain-Laval et file vers le sud-est, jusqu'à la D1089 où elle est de nouveau interrompue.
- Elle reprend sur la D112au sud de Feurs et continue vers le sud-est.
- Elle s'achève enfin sur la D16, à proximité de Virigneux.
