For many Parisians and tourists alike, the metro is part of their daily routine. Let's face it, the capital's public transport network is very practical when it comes to getting around Paris. What's more, RATP continues to expand its network and modernize its lines (notably in terms of automation), which sometimes means traffic disruptions for which we can be warned in advance.
From Porte de Clignancourt to Bagneux - Lucie Aubrac station, line 4 crosses Paris from north to south and vice versa, linking the two banks of the Seine. It stretches over 14km, linking three communes: Paris and two suburban towns in the inner suburbs, Montrouge and Bagneux, in theHauts-de-Seine (92) department of . Line 4 is particularly convenient, as it is the only line with connections to all other metro and RER lines except 3bis and 7bis. It's also the second busiest line in the Paris network.
But if you use line 4 of the Paris metro, or are planning to use it in the near future, be warned: on Sunday April 21, 2024, traffic will be interrupted on the entire line until midday. This interruption is due to modernization work on the line. " Teams are carrying out tests on the automatic driving system and final tests on the automatic shuttles," explains RATP.
