L'autoroute A48 est une autoroute permettant la liaison de Lyon à Grenoble.Elle se connecte à l'A43 au niveau de Coiranne (Bourgoin-Jallieu) et se termine à Saint-Égrève à proximité du centre de Grenoble au niveau de l'échangeur avec l'A480.Elle est surnommée « l'Autoroute du Dauphiné ». Ce projet, au niveau local (Métro et département) n'est pas très bien accueilli ; d'une part, en raison de l'engagement de l'État sur le plan financier qui reste très limité et d'autre part, en raison du manque de solution par l'État pour engager le réaménagement complet de l'échangeur du Rondeau, dépassé et vétuste, considéré au niveau local comme une des principales causes de l'engorgement du trafic routier, mais restant d'un coût élevé pour être uniquement assuré par les deux collectivités.
