Présentation

• La route nationale 703^E, ou RN703^E, est une ancienne route nationale française, antenne de la RN703, qui assurait un contournement Sud de la Roque-Gageac, entre Cénac-et-Saint-Julien et Castelnaud-la-Chapelle.

Historique

• Cette route est formée le 27 janvier 1961 en réponse à l'éboulement qui a détruit une partie de la Roque-Gageac en janvier 1957, coupant du même coup la RN703.
• Fait exceptionnel, une route de substitution est provisoirement classée pour rétablir la continuité de l'itinéraire. Elle récupère des sections des D46, D50 et D57.
• La RN703 est remise en service en 1965 et la RN703^E, devenue inutile, est déclassée le 21 avril 1967. Elle reprend dans la foulée ses anciens numéros.
