Modernisation Travaux Ligne 1

Metro line 1: works and closures

Due to modernization work, construction and closures are expected on line 1 of the metro in 2025. We will tell you everything.

Summary

  1. To adapt your journey

This summer, four tracks will be renewed at the Les Sablons station. The purpose of this renewal is to maintain their good availability and ensure optimal service throughout the line.

These works will lead to a closure of the metro line from August 11 to 31, 2025, between La Defense and Charles de Gaulle - Etoile stations.

A replacement bus BUSmetro ligne 1 will run in both directions between La Défense and Charles de Gaulle-Étoile. As far as possible, we invite you to use connecting lines, and to postpone your journeys as much as possible. Expect longer journey times.
