Summary

To adapt your journey

Due to an increase in work (replacement of two tracks at the Odéon station and the rail between the Cité and Saint-Germain-des-Prés stations, as well as waterproofing work at the Montparnasse station), the metro line will be closed between the Les Halles and Porte d'Orléans stations from July 5 to July 14, 2025.

Replacement buses will be offered to travelers between Denfert-Rochereau and Porte d'Orléans stations.
