The R line will also be interrupted in the daytime all weekend until 1pm between Gare de Lyon and Melun. The K line will be completely suspended this weekend between Gare du Nord and Crépy-en-Valois.

In short, this week, from April 27 to May 3, 2026, the works on the Île-de-France network intensify, with an exceptional closure of metro line 13 on Sunday morning until noon. May 1 weekend will be especially busy, with several major daytime disruptions on RER D and R up to 1 p.m. The RER E launches a new long-term project through July.
