Metro Lines 4, 12, 13 Close This Weekend Near Canal Saint-Martin
Works scheduled across Île-de-France will force residents who rely on central connections to reroute trips between July 18 and 19.
How we reported this
Metro service on lines 4, 12 and 13 will see partial suspensions this weekend, directly affecting Canal Saint Martin residents who travel south or toward central stations for work, errands or connections. The changes run from Saturday 18 July through Sunday 19 July 2026, with some sections closed until later dates.
Why the cuts matter now
These works form part of ongoing network maintenance and Grand Paris extensions that require weekend closures to avoid weekday rush-hour chaos. Canal Saint Martin locals often use these lines to reach Montparnasse or Concorde for onward travel, and the timing coincides with school holidays when some families still need reliable access to stations for day trips or returns.
Residents along the canal have already begun adjusting weekend plans after hearing about the closures from regular updates. One long-time area walker noted that the usual quick hop to Les Halles now requires extra time and a bus detour, while another described checking multiple apps each morning to confirm whether their usual route remains open. Many report building extra minutes into journeys to account for crowded replacement buses.
Lines and stations hit
Traffic on line 4 remains suspended between Montparnasse Bienvenue and Les Halles through 24 July because of construction. Line 12 service stops between Jules Joffrin and Concorde until 26 July for modernisation work. On line 13 the southern terminus shifts to Malakoff, Rue Étienne Dolet through the same date due to renovation. RER A faces reduced trains and no service at Nation station through late August, with further timetable tweaks during the holiday period. The source lists no announced disruptions for lines 1, 2, 3, 5, 6, 7, 8, 9, 10 or 11 this weekend.
Practical alternatives include checking the Île-de-France Mobilités app or Transilien.com before leaving, then using connecting bus routes where stations are closed. SNCF Connect also shows updated schedules. Canal Saint Martin riders heading toward affected central stops can plan extra walking segments or earlier departures to reach their destinations without last-minute surprises.
