Présentation

• La route départementale D77 (69), ou RD77 (69), est une route départementale de la circonscription départementale du Rhône (69) qui reliait Écully à la D30 près de Lozanne.
• En 1999 les traversées d'Écully et Dardilly ont été déclassées dans la voirie communautaire du Grand Lyon, ce qui a provoqué un petit changement de tracé et une confusion dans les cartes.
• Elle possède deux annexes :
  • La D77^E1 (ou D77^E selon certains panneaux) : elle relie Dommartin à la D385.
  • La D77^E2 : c'est une portion longeant l'ancienne N7 qui a été attribuée à la D77 après le déclassement de 1999.
• Depuis le 1^er janvier 2015, son exploitation est partagée entre le Conseil Départemental du Rhône (69D) et la Métropole de Lyon (69M).

Description du tracé

• La D77 débute historiquement à la limite entre Écully et Tassin-la-Demi-Lune, au niveau de l'échangeur du Valvert, sur l'ancienne N89, puis ancienne N7.
• Elle prenait l'Avenue de Verdun et passait au dessus de l'A6, puis traversait le centre-ville d'Écully.
• Elle traversait ensuite Dardilly et était interrompue par la D73 au croisement Chemin de Pierre Blanche - Route de Limonest - Route de La Tour-de-Salvagny.
• Elle avait un tronc commun avec la D73 jusqu'à la D307 (tracé repris par la N489 puis par l'A89 actuellement).
• Depuis le déclassement de 1999, la D77 débute un peu plus au sud de ce croisement, au lieu-dit Montcourant, reprenant le tracé de la D77^E2. Certaines cartes (Michelin, Apple maps) attribuent la portion entre Montcourant et le centre de Dardilly à la D77 alors qu'il d'agit d'un chemin communal appelé C2.
• Elle passe ensuite sous l'A89 et continue vers le nord.
• Elle traverse Dommartin, puis Les Calendrières (commune de Lozanne), et s'achève sur la D30.
