Metro, RER and trams: Summer of disruption on Paris public transport
Which means significant disruption on Metro, tram and RER lines over the summer period. Here's what to expect this year;
Metro
After postponing some projects last summer due to the Olympics, Metro operator RATP has a busy schedule of summer work that involves some level of disruption on almost all of the capital's lines.
Ligne 1:
Traffic will be interrupted between La Défense and Charles de Gaulle - Étoile stations from August 11th to 31st.
Ligne 3:
Traffic will be interrupted between Opéra and Gallieni stations from June 28th to August 3rd. Gallieni is the terminus, so in effect this means that only half of line 3 will be running during that five-week period.
Ligne 4:
Traffic will be interrupted between Les Halles and Porte d
'
Orléans stations from July 5th to July 14th.

Ligne 6:
Cambronne station will remain closed from June 30th until September 28th inclusive.
Ligne 7:
Traffic will be interrupted between La Courneuve 8 mai 1945 and Chaussée d'Antin - La Fayette stations between July 18th and July 24th.
Ligne 8:
No services between Concorde and Reuilly-Diderot stations from August 18th to 31st.
Ligne 9:
Traffic will be suspended along the entire line from 10.45pm on August 4th, to August 8th.
Ligne 12:
Traffic will be interrupted between Montparnasse and Mairie d
'
Issy stations from July 28th to August 7th inclusive.
Ligne 13:
Trains will not stop at Gabriel Péri station from July 14th to August 31st; Gaieté station will close from July 18th to July 20th; and Pernety station will be closed from July21 st to August 31st.
Ligne 14:
Traffic will be suspended along the entire line from August 4th to August 8th.
Trams
T1:
The T1 will be closed during the second half of July between the Gare-de-Saint-Denis and Hôpital-Delafontaine stops. Replacement buses will stop as close as possible to the stations.
T2:
Long-term work to improve operating conditions on the T2 line requires the redevelopment of the terminus at Porte de Versailles. The line will terminate at Suzanne-Lenglen station during works – which are scheduled to last until February 2026. A pedestrian route will be set up to allow passengers to connect between the two stations, which are 1km apart.
RER / Transilien
The RER netork, which serves Paris' outer suburbs including connections to Charles de Gaulle airport, has also extensive works planned, as have the greater Paris Transilien rail links.
RER A:
Services will be suspended on Line A between Le Vésinet-Le Pecq and Saint-Germain-en-Laye in the Yvelines department from August 9th to August 22nd for track equipment, sleepers, and ballasts to be renewed.
They will also be suspended from 10pm until the end of service between Rueil-Malmaison, Hauts-de-Seine, and Saint-Germain-en-Laye on Friday, August 8th, and Friday, August 22nd. Replacement buses will be provided, as well as taxis for people with reduced mobility.
Lignes A, L and J:
SNCF Réseau are carrying out overnight maintenance and modernisation work on the tracks on the Cergy (Val-d'Oise) and Poissy (Yvelines) branches in the Maisons-Laffitte area until June 29th, affecting services on Lignes L and J as well as RER A.

RER B:
To renew the track equipment ahead of the arrival of new trains, services will be suspended after the Denfert-Rochereau station from 10.45pm until the end of services on August 1st, as well as from August 4th to 8th inclusive, on August 11th and 12th, on August 14th, and from August 18th to 22nd.
Lignes B, D, H, and K:
The installation of the new cathedral bridge in Saint-Denis is continuing. The old structure will be dismantled from July 12th to 14th, requiring changes to services on lines B, D, and K. From August 15th to 17th, there will be a final interruption to restore signaling, which will affect lines B, D, H, K, and TER services.
RER B South and C South:
In parallel with the modernisation work on ligne C, SNCF Réseau has a project to relieve congestion south of Montparnasse station, which should eventually separate TGV and RER C traffic.
The creation of the new facilities requires the relocation of the RER B South tracks. As the RER C is right next to it, it will also have to be suspended during the work.
RER C services will be suspended from July 12th to August 23rd between Pont-de-Rungis and Massy-Palaiseau, and RER B services will be suspended between July 15th and August 27th between Croix-de-Berny and Massy-Palaiseau. A replacement shuttle service will be provided between the stations concerned. This does not affect connections to Charles de Gaulle airport.

RER C:
More than 120 projects are in the works on the longest and oldest line in the Île-de-France region, necessitating a six-week interruption of services from July 12th to August 23rd between Paris-d'Austerlitz and Avenue-Henri-Martin, Versailles-Château - Rive-Gauche and Saint-Quentin-en-Yvelines. During the closure, SNCF Réseau will replace 5 km of track and four sets of points, as well as reinforce flood prevention systems in a tunnel below the level of the Seine in Paris.
Meanwhile, work is nearing completion on the 150-year-old Pont des Souverains railway bridge that supports the 13 tracks at Saint-Lazare station – disrupting services on Lignes L and J run and RER C from August 1st to 12th.
And work is planned on the line at Saint-Ouen station to create two fire safety zones on the central section. As a result, the line will be closed between Avenue-Henri-Martin and Pontoise on July 26th and from August 1st to 23rd.
Finally, work replacing the overhead electricity cables in Essonne will affect RER C services.

RER D and R:
Work on access tracks to the technical centre at Villeneuve-Saint-Georges will be carried out overnight, Monday to Friday, until the end of 2025. Stations between Maisons-Alfort, Alfortville and Villeneuve-Triage will not be served in either direction every weekday evening.
RER E and Ligne P:
Overnight work will take place until August 23rd on sections of lines E and P to replace worn rails.
On the RER E, work will take place between Émerainville and Roissy-en-Brie in Seine-et-Marne, and on line P, it will take place between Verneuil-l'Étang and Longueville.
Separately, point-replacement work on Ligne P in Vaires-sur-Marne in Seine-et-Marne, will disrupt train services on weeknights from June 30th to August 22nd, as well as continuously on the weekends of July 19th and 20th, July 26th and 27th, and August 2nd and 3rd. In La Ferté-Milon, the replacement of 17km of track will also affect services for four weeks from July 15th to August 9th.
RER H North:
Modernisation work on the line will take place in the Bruyères-sur-Oise area in Val-d'Oise, affecting services during the weekends of June 28th and 29th and July 5th and 6th, and on weeknights until August 1st.
Ligne J:
Train service on line J will be disrupted in August due to maintenance work near the Bois-Colombes and Argenteuil stations. The work will take place at night on weekdays from August 11th to September 6th, as well as all day on the weekend of August 30th and 31st.
Ligne K:
Major track renewal work is planned between Dammartin - Juilly - Saint-Mard in Seine-et-Marne and Crépy-en-Valois in Oise. The work will take place at night, Monday to Friday until June 27th, and will disrupt late services.
Ligne R:
Track replacement work at
Livry-sur-Seine, Seine-et-Marne, and essential platform modifications at Fontaine-le-Port will lead to disruption Monday to Friday between 10.30am and 3.30pm from July 21st to August 29th, and continuously during the weekends of August 9th and 10th, and August 16th and 17th.

OPINION: Paris the 'new Amsterdam' for cyclists? As a Dutchman, I can tell you it isn't
As a Dutchman, my bike is half my personality - but I decided against bringing my bike to Paris when I moved here two years ago because I was afraid of Parisian thieves, and also curious about the Vélib' public bicycle system. After two years of commuting across the Seine on two wheels, I've grown so fond of it that it has become a highlight of my day. For someone new to Paris, I believe there is no better and healthier way of familiarizing yourself with the city than to be above ground at all times. I might not know where Metro line 5 meets line 9 but I know how to bike from Gare de l'Est to the Paris Catacombs (20 minutes straight ahead, zero turns). And if you are willing to throw your head over your shoulders a few times, you catch the Eiffel Tower, Sainte-Chapelle, Notre Dame, Pantheon and Jardin du Luxembourg all along the way. Advertisement During these two years on the Vélib', I've seen a serious amount of new bicycle lanes arise – my own street is currently under construction – so the city's commitment to the bike cannot be denied. But to say Paris has become the new Amsterdam? I have to stop you right there. Now, I don't mean to come across as a self-proclaimed biking expert but my Vélib' account tells me I have cycled 3,088 kilometres in Paris so far, which is only 249 kilometres less than this year's Tour de France, so I allow myself to comment. Yes, four out of five times it's the quickest mode of transport and biking through Paris can be delightful. But no, that's not because of the infrastructure. Some intersections have been so strangely designed that I'm not even sure where I'm supposed to bike. And the cycle lanes remain pretty damn inconsistent; sometimes they are on the right side of the road, sometimes on the left, sometimes on the sidewalk, on the car lane, the bus lane, they suddenly stop, only go one way or there is none to be found. See, I am not saying Paris should be like Amsterdam. But if it wants to be, I recommend mayor Anne Hidalgo to hop on the next Eurostar to the bicycle capital of the world (sorry Copenhagen), famous for having more fietsen than people. There she will see that every single road in the city is fully accessible by bike, in both directions, free from potholes and confusing intersections. Hidalgo does deserve credit for her ambitions and efforts so far. In the past decade, €250 million euro has been dedicated to bicycle infrastructure as part of le plan vélo , which aims to make Paris 100 percent bicycle-friendly by 2026. As a result, Paris now has over 1,300 kilometres of bike lanes, the Velib' fleet has been expanded to 20,000 bikes and bicycle use increased by 34 percent between 2020 and 2024. Every morning I seem to share my bike lane with more and more Parisians. Advertisement Since 2016, the city hosts Paris Respire (Paris breathes), a bike celebration and environmental day where many roads are exclusively reserved for cyclists. Meanwhile a Vélopolitain network is being developed, which includes the RER V lanes (named after the RER trains and intended to link the city to the suburbs via cycle paths) and a 'green wave' traffic light system, providing a smoother flow of traffic. That being said, the reason why Paris is still nowhere near Amsterdam has less to do with the infrastructure than it has to do with the culture. In Paris, biking still feels semi-political, as if you are making a progressive statement. Or at least it's perceived as a subculture by outsiders. In the Netherlands, we really do breathe biking, no matter if it's in a suit, skirt, with groceries or children. I still remember my mom biking through town with me and my brother on the back and grocery bags hanging from the handlebars. And no, that was no electric bike. Advertisement Last month, my flatmate and I went to our university's graduation ceremony in a suit and he refused to bike to the venue. Very Paris, not very Amsterdam of him. The same goes for my friends who laugh at me for taking the bike while they are waiting on their night bus to come. As long as many Parisians do not bike depending on the outfit, the weather or the occasion, it's not an integral part of the culture and the city won't adapt accordingly. Some other differences are the fact that everybody possesses their own bike in the Netherlands, which makes the mode of transport feel more like yours because you care about your bike. Rental is for tourists. And next to nobody wears a helmet, which for better or for worse indicates how normalised biking is. I would also like to point out that cycling with music in your ears is completely legal in the Netherlands, just like car drivers are allowed to listen to music. The Dutch police trust cyclists to care about their own safety and be careful. I wish the French police would do the same, instead of stopping me every six months. Advertisement Either way, biking in Amsterdam feels much safer, not only because of the infrastructure but also because car drivers are trained to anticipate cyclists, even when they wear no lights at night. What helps is that most Dutch children in primary school, including me, had to pass a theory and practical biking exam around the age of 11, something the French system is now slowly adopting in the form of a permis vélo . Just five years later, when we were 16, three friends and I felt comfortable enough biking to Paris for our first holiday without parents. During this trip we were confronted with a big difference between the Dutch and the French landscape: hills. Where the Netherlands is flat as a pancake, French and Parisian hills can be quite steep – think Montmartre or Belleville – and that makes the city less bike-friendly. Some slopes really require an electric bike which is quite the investment. This explains why Vélib' has 470,000 subscribers by now, because it offers electric bikes relatively cheaply or it allows you to bike downhill and take the metro back up. I sometimes do this too, receiving the occasional ' connard ', when I cross an intersection a little too fast or assertively. I'm pretty proud I only received one ticket over the past two years, which in all honesty was a fair one because I crossed a red light while having my earphones in (which is legal in the Netherlands, as I tried to explain to the police officer). In October 2024, Paris was shocked by an incident in which a motorist drove over a cyclist and killed him after the two had an argument in traffic. According to witnesses, the car was driving on the bike lane and drove over the foot of 27-year old Paul Vassy, who told the motorist off before being deliberately run over. This tragic incident exemplifies the intensifying battle for space in Paris traffic. Historically, the car has always had priority in the city and now it has a hard time coming to terms with the new reality. It's true that Hidalgo is rolling out le plan vélo at a faster rate than many Parisian minds can comprehend. So, is Paris the new Amsterdam? Not quite. I have no doubt that the French capital has the potential of becoming a real biking city, where bike lanes are free from potholes and there is no risk of ending up underneath a car. But in 2025, we are not there yet. What will it take? More bikers to bike more, so that the two-wheeler becomes as socially and culturally accepted as pedestrians. And for any cyclist who still has a free week this summer, I invite you to take the next exit to Amsterdam and come have a look for yourself. Do you cycle in Paris?

Paris confirms end of paper Metro tickets
From June 1st 2026, the slim rectangular cardboard ticket will no longer be valid for a ride on Paris' Metro, bus, tram or RER train network. However people who still have tickets will still be able to convert them into an 'Easy' transport pass until September 2026. The final death knell for the tickets - which measure 6.5cm x 3cm and have existed in the current form with a magnetic strip since 1973 - will be confirmed on Thursday where the Ile de France Mobilités board will vote on the timetable for ending the ticket. Advertisement The network has been gradually replacing the paper tickets with passes or digital tickets since 2018, and already some Metro stations on the network have stopped selling paper versions of the ticket. The carnet of 10 paper tickets was phased out first, while regular passengers were encouraged to switch to passes, travel cards or app payments which offer a lower per-journey fare. Single-journey tickets are still sold at some stations and are accepted for travel throughout the network. However from June 1st 2026 the paper ticket - some version of which has existed since Paris opened its first Metro line in 1900 - will fade into history. "A historic ticket for getting around, the ticket carton is becoming increasingly obsolete with the digitisation of transport tickets, which facilitates ticket storage, reduces cardboard waste and environmental impact, and makes it possible to avoid queuing at ticket offices thanks to smartphone purchasing,' explained IDFM in a statement. The cardboard tickers are especially prone to demagnetising if left in a pocket or wallet too long, meaning they can no longer be read by ticket machines. In addition to the weekly, monthly or yearly Navigo passes, the Paris transport operator has been rolling out passes aimed at visitors or occasional Metro users. These include the Liberté + - which is charged on a pay-as-you-go rate, charging journeys at €1.99 rather than €2.50 - or the Easy - a card that is loaded up in advance with pre-paid virtual tickets. The Ile de France Mobilités app also allows people to purchase tickets and passes in a digital format, in which the phone itself becomes the travel pass. READ ALSO : App, Navigo or Easy - What's the best option when buying tickets for the Paris Metro?✎ The Paris Metro ticket has always been rectangular, but over the years it's been many different colours including red, yellow, green, orange and purple. Advertisement In 1900, you would pay 15 cents (of France's previous currency, the franc) for a second-class ticket and 25 cents for first-class - first class carriages remained in use on some lines until 1991. Originally Metro tickets were checked by employees known as a poinçonneur ( poinçonneuse for women) - ticket-punchers. One of singer Serge Gainsbourg's early hits was Le Poinçonneur des Lilas, about the ticket-checker at the Les Lilas station. In gratitude for the recognition, a new station on the extension of Metro Line 11, which runs through Les Lilas, was named Serge Gainsbourg in 2024 (the new station is actually in the neighbouring suburb of Romainville, but let's not split hairs). But from the start of the 1970s, the ticket-punchers were replaced with automated barriers for checking tickets and a new Paris sport was invented - athletically vaulting over the barrier in order to fare dodge. You might think this is shady behaviour, but Jacques Chirac was famously photographed doing it while he was mayor of Paris (or at least he staged a photo that looked like he was doing it).

Parisians take a historic plunge into the River Seine after 100 years
Parisians on Saturday jumped into the river Seine —legally—for the first time in more than 100 years, with cries of "woo" and "it is warm!" ringing out across the Seine. It comes as public swimming was allowed in designated areas of the Seine, including two newly built wooden decks near the Eiffel Tower and the Île Saint-Louis in central Paris. Before sunrise, a municipal officer skimmed away the last few patches of algae with a fishnet. Soon after, a line of eager Parisians formed, towels in hand, waiting for their chance to jump in. Wows and cries of joy echoed across the riverbanks as the first swimmers entered the emerald-green water. Under the careful supervision of a dozen lifeguards wearing high-visibility vests, each swimmer donned a bright yellow lifebuoy fastened around their waist. The current was weak, just enough to tug gently at their limbs—a reminder that this is still a living, urban river. 'It's so nice to swim in the heart of the city, especially with the high temperatures we've been having lately,' said Amine Hocini, a 25-year-old construction worker from Paris. 'I'm surprised because I thought it was going to be cooler, and in fact, it's much warmer than I thought.' The return to swimming follows a 1.4 billion euro cleanup project tied to last year's Olympics. Officials now say the Seine meets European water quality standards on most days. Mayor Anne Hidalgo, who already took a dip last year, was there Saturday morning, holding up a transparent bottle filled with river water as a show of confidence. She said, 'It's a childhood dream to make people swim in the Seine." Water Quality is 'exceptional' Meanwhile, environmental authorities confirmed bacteria levels were well below official thresholds. "The water quality is 'exceptional,'" said Marc Guillaume, the prefect for the Paris' Ile-de-France region. "We are monitoring two bacteria, E. coli and enterococci, and for one we are ten times below the thresholds and for the other more than 25 times below," he said. From the deck, tourists and morning joggers stopped to watch. Some applauded as swimmers climbed up the steel ladders, grinning and dripping. Others, like François Fournier, remained sceptical. 'I won't risk it, quite frankly,' said Fournier, who lives atop the riverbanks and observed the scene from a bridge above. 'I've seen things you can't imagine floating in the Seine, so I'll wait for it to be really squeaky clean.' Floating debris still bobbed here and there—a stray leaf, a plastic wrapper—but the smell was barely noticeable: no strong sewage odour, just an earthy, river-like scent. 'This is so chic, to swim in the Seine, next to Île Saint-Louis,' said Lucile Woodward, 43, a resident. 'There are some apprehensions, of course, any time you go to swim somewhere, but I think this is one of the most tested areas in the whole world now. I don't think the town hall can allow itself to have any problems.' She added with a laugh, 'My skin is OK.' Swimming in the Seine had been illegal since 1923, with a few exceptions, due to pollution and risks posed by river navigation. Taking a dip outside bathing areas is still banned for safety reasons.
