Présentation

• L'agglomération de Quimper dispose de plusieurs itinéraires qui permettent de contourner la ville. Cependant, ces différents axes ne sont pas continus et ils présentent plusieurs points singuliers qui nuisent au détournement du trafic du centre-ville.
  • La rocade de Quimper en elle-même est assurée d'Ouest en Est par : le Boulevard de France, à 2x2 voies et échangeurs dénivelés ; de boulevards à 2x2 voies partiellement dénivelés nommés D785, D34 et D783^A ; d'une simili rocade Est jusqu'à la Route de Brest, successivement composée de 2 voies, 2+1 voies séparées, 2x2 voies dénivelées, 2+2 voies (séparées par une simple ligne blanche !). Cette rocade proche du centre-ville présente plusieurs giratoires géants qui saturent régulièrement en heures de pointe. Elle est également très incomplète puisqu'il lui manque tout un tronçon nord pour permettre d'avoir une boucle continue autour de la ville. Avec l'urbanisation très dense, ce tronçon appelé "Boulevard Nord", bien qu'ayant été déclaré d'utilité publique, ne sera finalement jamais construit, et on lui préférera un tracé plus lointain, qui deviendra le Contournement Nord-Ouest.
  • Le contournement de Quimper entièrement dénivelé permet de contourner la ville par le Nord et l'Est, il est composé de deux axes : la D100 et la N165 donnant accès aux routes de Douarnenez, Locronan, Brest, Saint-Brieuc et Lorient. La N165 à 2x2 voies dénivelée permet spécifiquement au trafic de transit (Nantes-Brest) de contourner Quimper par l'Est.
  • Plus à l'Ouest, un pseudo-contournement Ouest est assuré par la D56 entre la D765, la RN784 et la RN785. Cet axe à 2 voies non dénivelées donne également accès à l'aéroport de Quimper.

Anecdote

• A l'origine, le boulevard d'Ergué Armel (entre le rond-point du même nom et celui de l'Eau Blanche) a été construit et mis en service à 2x2 voies. Ce boulevard a une déclivité très importante : il y a plus de 50 m de dénivelé entre les deux ronds-points pour une distance d'environ 700m, soit une pente moyenne de plus de 7 %. En plus de cette descente dangereuse, le dernier virage pour arriver au rond-point de l'Eau-Blanche (celui du bas) est à droite, et la fin du virage est totalement invisible à cause du talus densément boisé. Ce rond-point est régulièrement saturé aux heures de pointe, ce qui a pour conséquence des remontées de trafic sur le boulevard d'Ergué Armel. Le trafic descendant ayant tendance a sous-estimer sa vitesse, il y a eut de graves accidents de tamponnage par des véhicules n'arrivant pas à s'arrêter à temps. Afin de remédier à ce problème, il a été décidé de supprimer une voie dans le sens descendant.
