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.

Entièrement située en milieu urbain et gratuite, elle sert de trait d'union entre l'A48 et l'A51. L'autoroute A48 est une autoroute permettant la liaison de Lyon à Grenoble.

Le passage à 2 × 3 voies, sans élargissement de l’emprise autoroutière, est alors acté, avec un maintien à 2 × 2 voies au-delà des échangeurs de Sassenage et du Rondeau. La limitation de la vitesse à En parallèle avec le projet d'élargissement à trois voies, des travaux sont initiés dès la fin de l'année 2018 afin de créer une nouvelle bretelle d'accès entre l'autoroute, le secteur du pont du Vercors et la presqu'île de GrenobleLe projet a été estimé à 380 millions d'euros dont 300 millions supportés par AREA pour l'A480 et 80 millions pour l’échangeur financés à hauteur de 43 % par l’État, 28 % par la Selon le site officiel du ministère des transports et de l'écologie, le calendrier de l'ensemble des chantiers spécifique au nouvel aménagement de l'A480 se présente ainsiLes travaux d'aménagement du secteur du Rondeau, dont les études sont en cours en 2019, devraient commencer à partir du Parallèlement au chantier, un mur protecteur anti-bruit végétalisé, dénommé « Natura Wall », est installée le long de la voie autoroutière afin de protéger certains riverains (côté Grenoble) du bruit lié à la circulation automobile« Toutes les routes qui ont déjà été élargies ont fini par subir une augmentation du trafic.

Cette voie permet aussi le lien avec l'autoroute A41 par l'intermédiaire de la Rocade sud de Grenoble.

Sortie 5: Seyssins, Sessynet km 8

Elle est surnommée « l'Autoroute du Dauphiné ».
