Présentation

• La route départementale D77 (69), ou RD77 (69), est une route départementale de la circonscription départementale du Rhône (69) qui reliait le quartier de Vaise, dans le 9^e arrondissement de Lyon, à la D30 près de Lozanne. Elle était définie comme la route de Vaise à Lozanne.
• La portion initiale à Lyon a été déclassée à une date inconnue entre 1973 et 1999.
• 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 RN7 qui a été attribuée à la D77 après le déclassement de 1999 et qui a été légèrement rectifiée suite à l'aménagement de l'échangeur 40 de l'A89.
• Depuis le 1^er janvier 2015, son exploitation est partagée entre le Conseil Départemental du Rhône (69D) et la Métropole de Lyon (69M) qui conserve son numéro D77 pour la portion non déclassée jusqu'alors.

• La D77 débutait historiquement Place du Marché, dans le 9^e arrondissement de Lyon. Elle partait vers l'ouest en suivant la Rue du Bourbonnais.
• Arrivée à la limite entre Écully et Tassin-la-Demi-Lune, au niveau de l'échangeur du Valvert, elle franchissait la Rue Marietton (ancienne RN7 puis RN89).
• 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 RN489 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.
