Présentation

• La route départementale D121 (38), ou RD121 (38), est une courte route départementale de l'Isère (38) qui relie Moirans à La Buisse.
• En l'absence de déviation par des axes routiers départementaux, cette route fait partie intégrante de la rocade de Voiron.
• Elle possède une annexe : la D121^A qui relie la D121 à la D1085 en direction de Voreppe.

Historique

• Cet axe est mis en service en 1998 afin de desservir l'échangeur de Moirans-Mauvernay (sortie 11 de l'A48).
• Grâce à un barreau rejoignant la D1085 en direction au Sud (D121^A), il est possible d'éviter La Buisse depuis 2006 sur l'axe Grenoble - Voiron. Dans les faits, ses caractéristiques médiocres n'en font pas un axe très emprunté.
