Metro line 4: anticipate your Paris journeys with this closure scheduled for several days in April

For many Parisians, it’s news that will complicate their daily lives. Metro line 4 will close for several days in April 2026. This interruption will affect one of the capital’s busiest routes.

Total closure of metro line 4 in April

RATP has confirmed this major shutdown. From Saturday April 5 to Monday April 7, 2026, line 4 will be completely closed. No trains will run between Porte de Clignancourt and Bagneux – Lucie Aubrac.

The closure comes over a long weekend. As a result, thousands of passengers will have to find alternatives. The decision was not taken lightly by RATP teams.

The aim of this work is to modernize the infrastructure. They will also ensure the long-term safety of users. Metro line 4 transports hundreds of thousands of people every day.

“Line 4 will be completely closed from Saturday April 5 to Monday April 7, 2026.

Why is this interruption necessary?

RATP is taking advantage of these days to carry out technical operations. Some work can only be carried out when there is no traffic. This guarantees the safety of our agents and the quality of our work.

Line 4 has recently been automated. Nevertheless, adjustments are still sometimes necessary. These occasional closures are therefore part of the continuous improvement process.

• Closed from Saturday 5th to Monday 7th April 2026
• No traffic between Porte de Clignancourt and Bagneux – Lucie Aubrac
• Maintenance and modernization work
• Alternative solutions will be proposed
• Normal traffic expected to resume after April 7

Alternatives for getting around without metro line 4

Faced with this interruption, you’ll need to get organized. RATP usually provides replacement buses. These shuttles serve the main closed stations.

Other metro lines can also provide a solution. Line 12, for example, follows a similar route on certain sections. On the other hand, it is likely to be busier than usual.

RER B is another option. It crosses metro line 4 at several strategic points. Remember to check the timetable before you leave.

Walking can sometimes be quicker. For short distances, this solution avoids the stress of crowded transport. Cycling is also a practical alternative in April.

Practical advice on how to prepare for these closing days

Allow more time for your journeys. Connections will take longer than usual. Leaving earlier will save you a lot of inconvenience.

Consult the RATP application the day before and the same day. Real-time information will help you adjust your itinerary. These tools are now indispensable for regular users.

If you can, postpone your travels. This long weekend falls during the Easter vacations. Many Parisians may be absent from the capital.

What the closure reveals about the Paris network

Metro line 4 is one of the oldest in Paris. It crosses the city from north to south. Its central role explains why its closure is having such an impact.

With recent automation, the line has become more regular. However, maintenance phases remain unavoidable. These outages, though inconvenient, pave the way for the future of the network.

Users will have to adapt temporarily. Patience will therefore be required over the next three days. Fortunately, this type of interruption remains exceptional on this metro line.

RATP communicates regularly about this work. Stay tuned for announcements in stations and on official networks. Your daily commute will return to normal on April 8, 2026.
