Présentation

• La route nationale 137, ou RN137, est une route nationale française qui desservait historiquement le Grand Ouest de la France, entre Bordeaux et Saint-Malo.
• Il ne subsiste actuellement que 3 sections de l'axe historique :
  • Voie express entre Rennes et Nantes.
  • Boulevard Périphérique Est de La Rochelle.
  • Rocade Sud-Est de Saintes.
• Il faut enfin noter que le tracé allant de Saint-Malo à Rennes appartient à la Voie de la Liberté qui emprunte à la fois l'ancien parcours et l'actuel. Les bornes de la Liberté sont toujours présentes sur le terrain.

Historique

Généralités

• A sa création, en 1824, elle est décrite comme étant la route de Bordeaux à Saint-Malo par Rochefort, la Rochelle et Nantes. Elle s'embranche un peu au delà de Saint-André-de-Cubzac, sur la route n° 10 de Paris à Bayonne. La partie aux abords de Rochefort appartient à la route n° 11 de Paris à Rochefort et la partie depuis la Rochelle jusqu'à Usseau appartient à la route n° 22 de Paris à la Rochelle. Elle succède alors à la Route impériale 157.
• A l'origine, la RN137 reliait donc Saint-André-de-Cubzac, au Nord de Bordeaux, à Saint-Malo. On lui adjoint plusieurs annexes en 1933.
• Lors de la réforme de 1972, elle a absorbé l'ancienne RN137^A qui contournait Blaye, de même que l'ancienne RN137^D qui contournait La Rochelle. On notera que son tracé a été légèrement modifié lors de la construction des différents tronçons de voie express qui émaillent son parcours.
• En 1978, la RN137 est définie plus précisément comme la route Saint-André-de-Cubzac, N. 10, à Saint-Malo.
• Classée en grand axe d'aménagement du territoire, la RN137 bénéficie de nombreux travaux. Par la suite, la construction de l'Autoroute des Estuaires affaiblit le trafic de la RN137 qui n'écoule plus qu'un trafic essentiellement local.
• C'est logiquement qu'une très grande partie de l'axe est déclassée en 2006. A cette date, seules quatre des principales sections aménagées en voie express subsistent : la rocade Sud de Saintes, le Boulevard Périphérique de La Rochelle, la section Rennes - Nantes et, très curieusement, la traversée de Saint-Malo.
• Complètement isolée du reste du réseau routier national et sans aucun intérêt stratégique, la traversée de Saint-Malo (entre la rocade PR113+185 et l'Esplanade Saint-Vincent au pied des remparts PR118+300) est restée classée dans le réseau routier national jusqu'au 21 juillet 2016. A cette date, elle intègre le domaine routier communal.
• A terme, il ne devait rien subsister de la RN137. En effet, une fois l'autoroute A831 achevée, la section Rochelaise aurait dû être déclassée, mais ce projet a été abandonné. Il était également prévu d'intégrer la section Rennes - Nantes à l'autoroute A84 après mise aux normes, ce projet étant également remis en cause. La rocade de Saintes aurait pu quant à elle être intégrée à la RN141 ou à la RN150 dans un souci de cohérence de la numérotation.
• Depuis le 1^er janvier 2017, la section du tracé historique non aménagée en voie express ainsi que la section de voie express en direction de Saint-Malo, situées sur le territoire de Rennes Métropole, ont été reclassées en tant que route métropolitaine en conservant leur ancienne dénomination, soit M137, M637 et M837 suivant les sections. Au même moment, les sections du tracé historique non aménagées en voie express situées sur le territoire de Nantes Métropole, ont été reclassées en tant que route métropolitaine en conservant leur ancienne dénomination, soit M137 et M537 suivant les sections.

Étude de tracé de 1974 de la section Saint-Malo - Rennes

• En 1974, des études préliminaires furent lancées afin de déterminer sous quelle forme devrait être aménagé l'axe entre Saint-Malo et Rennes, ainsi que le tracé que devrait adopter ce dernier.
• En ce qui concerne le tracé, trois grandes options étaient envisagées avec de multiples variantes :
  • La première consistait un tracé neuf situé à une dizaine de kilomètres à l'Est de la route historique, ce tracé suivant grossièrement les D73 et D82 en passant à proximité de Combourg. Ce tracé comportait deux sous-variantes, l'une se détachant de la RN137 au niveau de Saint-Jouan-des-Guérets, l'autre au niveau de la bifurcation avec la RN176. A tout cela, s'ajoutaient les points d'échanges avec le réseau existant, en fonction de la finesse choisie pour la desserte du territoire et de la sous-variante retenue. Le nombre d’échangeurs devait être compris entre 6, 7 et 9.
  • La seconde option, elle aussi en tracé neuf, se tenait quant à elle à l'Ouest de la RN137 historique en ne s'écartant qu'assez faiblement de celle-ci. Comme pour l'option précédente, deux sous-variantes étaient envisageables au Nord du tracé, l'une quittant la route historique à Saint-Jouan-des-Guérets, la deuxième ne la quittant qu'après l'échangeur avec la RN176. A l'instar de la première option, différentes possibilités concernant les échangeurs furent proposées faisant varier le nombre de point d'accès à l'axe de 6 à 9.
  • La troisième et dernière option était celle d'un aménagement sur place de la route existante, combiné à la réalisation de déviations pour éviter les principales agglomérations le long du parcours. Avec cette solution seules les parties neuves devaient avoir des franchissements dénivelés. Les parties aménagées sur place devaient conserver en grande partie des carrefours à niveau sauf au niveau de l’intersection avec la D794 ainsi qu'au niveau de quelques points singuliers où le relief risquait de rendre dangereux ce type de franchissement. Au niveau des axes à fort trafic, des points d'échanges dénivelés étaient prévus, soit un à chaque extrémité du projet ainsi qu'au niveau de la D74, de la RN176, de la D794, D20, D221 (Nord de La Mézière) et de la D27.

• Pour ce qui est du type d'aménagement à retenir, plusieurs solutions furent proposées :
  • Route à 2x2 voies avec carrefours à niveau.
  • Route à 2x2 voies sans carrefours à niveau.
  • Autoroute sans péage.
  • Autoroute à péage.

• En combinant toutes les possibilités de tracé, de types d'aménagement et du nombre de points d'échanges, ce ne furent pas moins de 16 solutions qui étaient envisageables. Après étude du coût de chaque solution et du bénéfice que chacune d'entre elle pourrait amener, il fut décidé d'écarter toutes les solutions Est bien moins rentables que les autres solutions, ainsi que les options à péage qui, par leur moins grande attractivité, offraient un bénéfice actualisé plus médiocre que le reste des hypothèses. Il en allait de même avec les propositions de route avec des carrefours à niveau, dont l'option ASP, qui par leurs moins bonnes caractéristiques n'offraient pas un service rendu à l’usager satisfaisant.
• Il ne restait alors que les quatre options autoroutières Ouest sans péage : bien que relativement comparables dans leurs coûts de construction et dans leurs niveaux de services rendus, la solution ayant le meilleur bénéfice actualisé était celle d'un tracé se détachant de la route historique après la bifurcation avec la RN176 (configuration qui permettait de récupérer le tronçon en cours de mise à 2x2 voies entre Saint-Malo et la RN176) et avec un nombre total de 9 échangeurs répartis tout au long du parcours (les solutions comportant moins d'échangeurs s’avéraient être moins rentables, à cause, de leur moins bonne desserte du territoire).
• Le projet évolua quelque peu par la suite en raison des contraintes budgétaires poussant les ingénieurs à adopter une solution hybride mariant ASP et tracé neuf Ouest. Un second poste d'économie fut réalisé en se rabattant sur une solution de type voie express et non plus autoroutière. Ces différentes mesures permirent de fractionner le projet en plusieurs tranches fonctionnelles et ainsi de maintenir des coûts raisonnables sans trop rogner sur la qualité de l'aménagement.
• De légères économies furent aussi réalisées sur les quelques rares sections où l'aménagement se fit par reprise de la route existante pour l'une des deux chaussées de la 2x2 voies, avec le maintien à niveau des intersections dans un premier temps. Ces dernières furent finalement dénivelées entre le milieu des années 1990 et le début des années 2000, cette dénivellation s'accompagnant d'une amélioration des axes de substitution pour les véhicules interdits sur VE de part et d'autre de ces intersections.

• Voici ci-dessous les tracés étudiés en 1974 par le CETE de Nantes :
