Présentation

• La route départementale française D2 (78), ou RD2 (78), est une route départementale située dans le département des Yvelines (78) qui relie le hameau de L’Hautil (commune de Triel-sur-Seine) à Vernouillet, soit la D22 à la D154. Elle est en tronc commun sur 200 m avec la D190 à Triel-sur-Seine centre.

Historique

• La D2 a vu son tracé se modifier en 1956, lors de la mise en service du pont suspendu de Triel, qui avait pour but de remplacer l’ancien pont inauguré en 1838 et détruit en 1940 par le génie militaire français pour ralentir la progression allemande.
• Le nouveau pont a été construit 200 m en amont de l’ancien, ce qui a légèrement modifié le tracé côté Vernouillet et engendré un tronc commun avec la D190 côté Triel-sur-Seine.

Futur

• Rien d'impressionnant n’est prévu sur la D2, bien calibrée pour son trafic qui reste raisonnable, notamment grâce à la construction du pont de Triel-sur-Seine sur la D1 en partie parallèle.
• Seul un réaménagement à Vernouillet ainsi que sur le pont suspendu de Triel est à l'étude afin des privilégier piétons et cyclistes.
