Présentation

• La route départementale D42 (69), ou RD42 (69), est une route départementale de la circonscription départementale du Rhône (69) qui relie Lissieu à Limonest.

Historique

• Cette route est l'unique vestige de la longue D42 qui contournait initialement Lyon par l'Ouest pour se terminer à la Madeleine. Une grande partie de son tracé a été renumérotée en D342 en 2006.
• La D42 actuelle correspond à un ancien tracé de la RN6, avant que celle-ci ne soit rectifiée un peu plus à l'Ouest pour éviter un relief prononcé.
• Depuis le 1^er janvier 2015, elle est intégralement située sur le territoire de la Métropole de Lyon (69M) qui assure son exploitation.

Annexes

• La D42 possède deux annexes :
  • La D42^A (69M) à Sainte-Foy-lès-Lyon, dans le quartier de Beaunant, qui est probablement un ancien tracé de la D42 (69M) avant une déviation. La D42^A a été déclassée à l'exception de la petite portion au sud de la D50 (69M). Une autre portion de la D42^A (69D) permet de relier la D342 (69D) à la D386 (69D) aux Sept-Chemins.
  • La D42^E (69M), qui reliait la D42 (69M) au Boulevard Périphérique Nord (TEO). Elle a été renommée D342 (69M) en 2006.
