City centre

Avenue de Versailles > Place de l'Europe

The concession works that will be held in the city centre of Poissy will have consequences on car traffic:

• Access to Rue de la Bruyère will be reserved for local residents.
• Between Rue Charles Maréchal and Boulevard Devaux, Boulevard Gambetta will be one-way until February 2025.

When possible, it is therefore recommended to avoid the area during the work period.

All shops remain accessible during the work period.

The Greater Paris Seine et Oise Urban Community (GPSEO) will carry out a large part of the upcoming concession work at the end of 2024 and in the first half of 2025. GPSEO's intervention consists of diverting the existing water networks to allow the construction of the extension of the T13 tram.

This work will make it possible to:

• Modernisation of the drinking water network, reducing the risk of leakage The old pipes made of grey cast iron, a brittle material that is no longer used today, will be replaced.
• The sewerage networks will be partially separated, in order to reduce the volumes of clear water transported to the treatment plant and to reduce the risk of spillage into the natural environment during rainy weather.
