From November 18 to 29, major work will take place on lines L, A and J. Find all the impacts for you as well as my advice:
The Paris Saint-Lazare <> Gisors/Pontoise and Paris Saint-Lazare <> Mantes la Jolie via Conflans Sainte-Honorine branches of line J will soon be subject to major works which will cause traffic interruptions on these two axes. These disruptions, although temporary, will require you to plan your trips in advance, because the RER A and line L will also be impacted.
I invite you to discover here the details of the work, their impact on your daily life, as well as alternative solutions to minimize inconvenience.
