Transport in Île-de-France: disruptions and roadworks this weekend of August 29–30, 2026

The RATP and SNCF networks are set to experience new disruptions this weekend of August 29–30, 2026. Several RER, Transilien and metro lines will be affected by maintenance work and service interruptions, and here’s everything you need to plan your travel.

A new maintenance weekend on the RATP and SNCF networks in Île-de-France is planned from Saturday, August 29 to Sunday, August 30, 2026 to push ahead with the Grand Paris projects, the upcoming metro line extensions, or simply to keep the network in good repair. Will this weekend see a flurry of works, or will it be a quiet one?

Be aware of potential traffic disruptions and train cancellations, which often require提前 planning to avoid surprises. To find alternative routes when you need to travel, visit Transilien SNCF, where you’ll find alternative options, including regular bus services that connect to the stations.

Here’s what’s scheduled for this weekend, August 29–30, 2026.

Stay tuned, as the information may be updated based on the latest updates from RATP and SNCF.
