Pont ferroviaire de Conflans-Sainte-Honorine

About

The viaduct Joly de Conflans-Sainte-Honorine is a wired viaduct crossing the Seine for 185 metres at Conflans-Sainte-Honorine. It is an art work of lines A of the RER of Île-de-France and L of the Transilien, these two lines serving Cergy. It is thus borrowed by the line of Achères to Pontoise or to Creil.

Until 1988, Dieppe could be reached by borrowing the original line from Saint-Denis to Dieppe. Thanks to the fairly recent electrification to Serqueux, this line constitutes a route-bis from Paris to Rouen.
