[1]: 171  Porte de Bagnolet also constitutes one of the main access routes to the interior of Paris as well as the starting point of the A3 autoroute.

As part of the RATP's Metro Renewal program, the station's corridors were renovated on 16 November 2004.

[3] The station has five entrances, each decorated with a mast with a yellow "M" inscribed in a circle: Although the station was built in the 1970s, the sides of the corridors and the platform areas are covered with traditional bevelled white tiles following their modernization completed in late 2004.

The decoration, typical of the 1970s, is like the Mouton-Duvernet style with walls covered with bevelled beige tiles placed vertically and aligned, a white painted vault as well as two hanging lighting strips.

The metallic advertising frames are grey and protruding, and the name of the station is written in Parisine font on enamelled plates.
