Summer 2026: intensive work to prepare the network of tomorrow
Why new work this summer in transport?
What do a metro every 85 seconds on line 14, a brand new train on the RER B and lines that extend to connect the entire region have in common? A mandatory passage through the works box.
In 2026, nearly €4 billion will be devoted to work to modernise and regenerate public transport in the Île-de-France region
Summer 2026: what are the objectives of the work?
The scale of the work carried out is unprecedented with the following objectives:
- To ensure the comfort and improve the punctuality and safety of passengers by renovating and modernising stations, stations and the infrastructure that needs them (from lifts to platforms, to switch systems)
- Prepare for the arrival of new trains (such as the MI20 on the RER B) and metros (such as the MF19, which will equip half of the metro lines by 2030)
- To develop the network to interconnect the entire region and simplify the daily life of Ile-de-France residents with the opening of new metro lines (the 15, 16, 17 and 18, the latter opening a first part of its route in 2026)
Which lines will be impacted?
- RER : A, B, C, D and E
- Metros : 4, 5, 8, 12, 13
- Trains : H, K and P
- Trams : T1 and T2
How to get around during the period?
Like the work carried out during the Paris 2024 Olympic and Paralympic Games to welcome a large number of passengers at the same time to competition venues, Île-de-France Mobilités has centralised all the information to make travellers' daily lives as simple as possible during the works.
How?
- With an online page that lists all the work by line, the dates of the disruptions and the alternative routes to get around.
- Replacement buses and the calculation of alternative routes to avoid congestion on the network and allow passengers to travel
- An app you can trust : the work schedule and route planner are updated in real time according to disruptions on the official transport app (available on iOS and Android)
Our advice for this summer
- If you can, promote teleworking and avoid rush hour
- For short trips : prefer to travel on foot or by bike
- Think about carpooling (included in your Navigo Annual subscription)
