Metro line 4: works and closures

To complete the automation work on Line 4, service will be suspended along the entire line on September 29, 2024, until noon.

Although the automation of Metro Line 4 is now in effect, a final intervention is necessary to complete the project. As a result, the entire line will be closed on Sunday, September 29, 2024, until noon.

We encourage you to use connecting lines during this period.
