On the departmental road D22, near the entrance to the village of Boissy-l’Aillerie, a new roundabout featuring a portal and surveillance cameras was recently inaugurated. The roundabout, which was completed as part of a project started under the former mayor, Michel Guiard, and continued by the current mayor, Paul Dubray, is designed to enforce a local regulation banning vehicles heavier than 7.5 tonnes from entering the village. The project, which cost approximately 2.2 million euros, was officially opened on October 8, 2026, following a decree signed in November 2022. Residents of Boissy-l’Aillerie had long been troubled by the high volume of traffic passing through the village, with over 5,000 vehicles traveling through daily. Of these, about 3% were heavy trucks, which contributed to congestion and safety concerns. The new roundabout includes a specialized portal that restricts the height of vehicles allowed through, alongside a system for scanning license plates or badges. This system permits only certain vehicles, such as buses, emergency vehicles, and agricultural equipment, to pass through. A camera near the roundabout is also in place to record license plate numbers, aiming to discourage violations and support legal enforcement if needed. Additionally, the roundabout includes a dedicated bike lane and a pedestrian path to ensure the safety of non-motorized road users. The initiative aims to redirect heavy trucks away from the village center and keep them on designated main routes. However, the local association Sécurité Routière Boissy-l’Aillerie has raised concerns that this measure might simply shift the traffic problem to other areas within the village. The association's president, Laurent Hetet, noted that the group was not consulted or informed about the project and plans to closely monitor any changes in traffic patterns around Boissy-l’Aillerie. The association is worried that rerouted traffic could increase congestion and safety risks on other local streets, such as Pasteur Street.
