Starting November 16, 2026, Rue Déjerine will be closed to car traffic between numbers 1 and 3, as part of the development of the future Parisian forecourt of the Porte de Montreuil.

The affected section, located between Square Déjerine and Avenue de la Porte de Montreuil, will undergo construction to create a green and pedestrian area. Pedestrian and cycle paths will be maintained throughout the construction period.
Car traffic will be diverted to Rue Mendelssohn, which will become one-way towards Boulevard Davout. This arrangement anticipates the final traffic configuration after the works.
By 2030, a large square will span the Boulevard Périphérique, strengthening the link between Paris, Montreuil, and Bagnolet. The Porte de Montreuil area, currently fragmented, will eventually host a unified metropolitan square.
The project aims to improve connectivity between the sector's various entities, including the flea market, sports facilities, a resource center, a gas station, and degraded public spaces, while considering the predominantly social housing.
