Présentation

• La route départementale D884 (01), ou RD884 (01), est une route départementale de l'Ain (01) qui relie Collonges à Saint-Genis-Pouilly, en contournant Genève par l'est.
• Cet axe qui fait partie du contournement français de Genève par l'Ouest est intégralement à 2x2 voies et classé en voie express.
• Il reste cependant inachevé faute d'une connexion directe avec l'autoroute A40 au Sud qui nécessiterait de construire une bretelle autoroutière avec un viaduc sur le Rhône et un nouvel échangeur à hauteur de Vulbens-la-Fontaine. Côté Nord, la peu capacitaire D35 assure la continuité en direction de Gex et Fernay-Voltaire, mais ses caractéristiques réduites causent des encombrements au quotidien.
• Un temps prévus, la dénivellation du problématique carrefour giratoire du CERN et le doublement dans la continuité de la déviation Est de Saint-Genis-Pouilly semblent désormais abandonnés.
