Paris, France (AP) — An underground tunnel connecting the rail lines to the metro system has been replaced with a sign reading “Welcome to the Metro.”

The sign in front of the metro station in Paris says it’s now the official metro station for the Parisian region.

The sign is located in front in the metro area.

Paris is one of several French cities that has seen a significant spike in subway use.

In addition to the rail line, Paris is also home to the subway, which is the country’s largest subway system.
