Présentation

• La route départementale D29 (91), ou RD29 (91), est une route départementale de l'Essonne (91) qui relie Viry-Châtillon (N7) à Athis-Mons, à la limite d'Ablon (Val-de-Marne) où elle est prolongée par la D249 (94).
• Son tracé est globalement parallèle à la Seine. Elle constitue une partie de l'itinéraire de liaison entre la N7 et la RN6, par Juvisy-sur-Orge (où son trajet est particulièrement complexe) et le pont de Villeneuve-Saint-Georges.
• La D296 peut être considérée comme son annexe à l'origine, bien qu'elle n'ait maintenant plus de liaison avec elle. Ouverte au début des années 1970, elle relie en effet Sainte-Geneviève-des-Bois (ancienne RN446, aujourd'hui D46) à Fleury-Mérogis, où passait alors la D29 (voir ci-dessous).

Historique

• La D29 est à l'origine une voie de l'ancien département de Seine-et-Oise, reliant Fleury-Mérogis (ancienne RN446, absorbée depuis par la Francilienne) à Chennevières-sur-Marne, à la limite de Champigny-sur-Marne (alors partie du département de la Seine), par Villeneuve-Saint-Georges.
• En 1944, les bombardements anglo-américains provoquent la destruction quasi-totale des abords de la gare de triage de Juvisy. Le quartier est donc reconstruit après-guerre, et un nouveau tracé de la route à Juvisy et Athis-Mons est achevé au début des années 1950.
• En 1968, l'éclatement de la Seine-et-Oise provoque le partage de la route entre deux nouveaux départements :
  • La partie Sud, de Fleury-Mérogis à Athis-Mons, revient à l'Essonne (D29 (91)).
  • La partie Nord, d'Ablon à Chennevières-sur-Marne, est attribuée au Val-de-Marne. Prolongée jusqu'au centre de Champigny-sur-Marne, elle garde le nom de D29 (94) jusqu'en 2009 ; elle est alors à son tour répartie entre les actuelles D249 (94), D229 (94), D124 (94) et D219 (94).
• De Fleury-Mérogis à Viry-Châtillon (N7), la route est progressivement aménagée pour accueillir une circulation importante : déviation du centre de Viry (1964), création d'une nouvelle avenue urbaine à 2x2 voies entre l'autoroute A6 à Viry-Châtillon et la Francilienne à Fleury-Mérogis (vers 1972-73). Cette section est finalement classée dans la voirie nationale de 1978 à 2006 sous le numéro RN445 (actuelle D445).

Futur

• Dans le cadre de la création du pôle multimodal de Juvisy-sur-Orge, le pont routier permettant le franchissement des voies de chemin de fer, mis en service en 1930, est en cours de rénovation depuis 2015. En particulier, la rampe Nord est entièrement reconstruite. Sa réouverture est prévue en 2019.

Autour de la route

• Pont des Belles-Fontaines, à Juvisy-sur-Orge
• Gare de triage de Juvisy
• Parc du Coteau des Vignes, à Athis-Mons
• Quais de Seine, à Athis-Mons
