The Directorate of Roads of Île-de-France (DiRIF) has announced the closure of access to the N104 westbound from the entrance roundabout of Le Mesnil-Amelot (slip road n°10) for a provisional period of approximately six months, starting from October 26, 2026.

This work is part of the Eastern Roissy Bypass project and aims to reduce noise pollution from highway traffic by constructing a noise barrier.
A diversion route will be implemented via the RD212 and the route de l’Arpenteur to allow users to reach the N104 westbound. Users are invited to follow the temporary signage installed on site.
Furthermore, the implementation of safety markings on the emergency lane necessary for the work will result in a reduction in the width of part of the slow lane, westbound. Additionally, the maximum authorized speed on this section of the lane will be reduced to 70 km/h instead of the usual 90 km/h.

"Aware of the inconvenience caused, the DiRIF will make every effort to limit the disturbances and thanks the residents for their understanding."
