Regular users know this.
The SNCF and the RATP take advantage of the drop in attendance and frequency, on Saturdays and Sundays, to carry out heavy work.
Again this weekend, several lines will be completely closed.
Navigation aid applications - normally - take these closures into account to show you the best route.
Think about it before crossing Île-de-France by public transport.
On RER lines
On the
RER B,
it will be difficult to get to Roissy-Charles-de-Gaulles airport.
Traffic is interrupted between Paris Gare du Nord and Aulnay-sous-Bois in Seine-Saint-Denis.
A replacement bus service has been set up, serving intermediate stations, departing from Saint-Denis Stade de France.
You can also opt for metro line 7 or buses 620, 148,150 which take you to certain RER stations not served by the RER.
On the
RER C
, no train runs between Pont de Rungis Orly Airport and Massy-Palaiseau in Essonne, due to work on the T12 tramway and the accessibility of Massy station.
Buses are set up and stop at intermediate stations.
But count on a strong extension of the travel time.
On the
RER D,
traffic is significantly slowed between Paris Gare de Lyon and Melun in Seine-et-Marne.
In addition, this Saturday, from 11:50 p.m., the Lieusaint station is not served, and this in both directions.
And on Sundays, from 10:30 p.m., trains are direct between Villeneuve-Saint-Georges in Val-de-Marne and Melun in both directions.
On
line P
, no train runs on the Provins axis, between Provins in Seine-et-Marne and Nogent - Le Perreux in Val-de-Marne.
You will have to fall back on the RER E between Haussman Saint-Lazare/Magenta and Nogent - Le Perreux.
Shuttles will also leave every hour.
From 10 p.m., Saturday and Sunday evening, the Château-Thierry axis will also be affected.
In the subway
The metro is also affected by traffic interruptions.
On Sunday, no train will run on the whole of
line 9
, from 5:30 a.m. to 9 a.m. Then, from 9 a.m., the service will only be partial.
It will remain interrupted to the west, between Trocadéro and Pont de Sèvres.
Replacement buses are put in place.
Finally, on
automatic line 14
, due to work related to the extension to Orly Airport, traffic will be zero on the entire line on Saturday and Sunday.
It will also be an opportunity for the RATP to speed up the creation of new accesses to the Gare de Lyon platforms.
Traffic will not resume until Monday morning.
