Transport in Île-de-France: Upcoming Works and Closures
This week, from Monday, November 3 to Sunday, November 9, 2025, several metro, RER, and Transilien lines in Paris and the Île-de-France region will face disruptions due to ongoing modernization projects.
After a short break, maintenance work resumes on both RATP and SNCF networks. These essential upgrades will cause service interruptions and replacement buses on many routes.
To minimize inconvenience, travelers should check the official RATP and SNCF Connect apps before traveling. The Île-de-France Mobilités website also offers real-time alternative routes.
This week promises to be challenging for commuters, so proactive planning is advised to avoid surprises.
