Montparnasse – Bienvenüe (Paris Métro)

At the end of the 1930s, a long corridor was built to connect the Montparnasse and Bienvenüe stations. Accordingly, the stations' names were fused to create Montparnasse-Bienvenüe on 6 October 1942. This long corridor is now equipped with moving walkways to facilitate access between the two parts of the station. The old Bienvenüe station serves lines 6 and 13, while the old Montparnasse station serves lines 4 and 12.

In 2002, in an experimental move, the RATP installed a moving walkway that moved at 12 km/h, which was then termed the "fastest in the world." (The speed has however since been reduced to 9 km/h). The first several metres consist of metal rollers that accelerate passengers as they hold onto the handrail, because it would be dangerous to step directly onto the fast-moving conveyor. However, RATP announced in May 2009 that they would replace the walkway with an ordinary one in March 2011 in response to 'numerous customer complaints concerning safety and unreliability'.

The southern part of the station in the Avenue du Maine was the location of the Barrière du Maine, a gate built for the collection of taxation as part of the Wall of the Farmers-General; the gate was built between 1784 and 1788 and demolished in the nineteenth century.[1][2]

The station has seven entrances:

• Entrance 1: Porte Océane: direct access to the SNCF station, stairs and escalators;
• Entrance 2: Place Bienvenüe: a staircase at 32 Avenue du Maine;
• Entrance 4: Tour Montparnasse: a staircase at Place Raoul-Dautry (between the tower and the train station);
• Entrance 5: Boulevard du Montparnasse: two staircases at 71 and 73 Boulevard du Montparnasse;
• Entrance 6: Rue d'Odessa: a staircase and escalator at 1 Rue du Départ;
• Entrance 7: Rue du Départ: direct access to the basement of the shopping center;
• Entrance 8: Rue de Rennes: a staircase at 59 bis, Boulevard du Montparnasse.

The platforms of Line 6 are decorated in the Mouton style with orange tiles and orange luminous lighting strips. Those of Line 12 are in the Ouï-dire style with green lighting strips and Motte seats, white flat tiles and white cylindrical advertising frames. The platforms of Line 13 are built in the Andreu-Motte style with green lightning strips and green tiled benches, tympanum's and openings. Green Motte seats are married with the original CMP decoration (white bevelled tiled walls, the name in faience and honey colour advertising frames). These platforms are equipped with platform screen doors. In 2017, the platforms of Line 4 were under construction.
