Question 15441 — nuisance

Summary

Mr. Emmanuel Duplessy draws the attention of the Minister of Ecological Transition, Biodiversity and International Negotiations on Climate and Nature to the noise and environmental pollution linked to the development of the A10 motorway in the Ingré sector (Loiret). Since the widening of the A10 to 2 x 4 lanes and the construction of a flyover at the A10/A71 interchange, the situation of local residents has deteriorated significantly: intensification of noise due to the resonance of metal structures, replacement of absorbing walls with reflective walls, lack of effective sound protection in certain sectors, notably north of Ingré and around the bridge on the RD2157. Furthermore, during the consultation and information phases of the project, visuals and communication elements presented by the Vinci company may have led certain local residents to consider that sound protection would be implemented in the sectors affected by noise pollution. However, the official documents relating to the project did not explicitly include these measures. This difference in interpretation today contributes to the incomprehension expressed by some local residents regarding the developments carried out and the commitments associated with the project. Acoustic measurements carried out by the company Vinci dealership in March 2024 concludes regulatory compliance, but they were carried out over a single week with low traffic and do not reflect daily reality. However, according to the recommendations of the World Health Organization, the noise levels endured by residents are largely excessive and have proven impacts on their health (sleep disorders, stress, anxiety). The summer of 2025 illustrated this dramatic situation: residents were unable to ventilate their homes during heatwaves as the noise was unbearable. Residents also denounce a loss of real estate value and a general deterioration of their living environment, while the profitability of motorways would make it possible to invest in suitable sound protection. He therefore wishes to know what measures the Government intends to take to require motorway concessionaire the implementation of truly effective acoustic and environmental protection, consistent with the initial commitments presented during the public consultation and consistent with WHO recommendations; guarantee the completion of new independent acoustic studies, carried out over a period representative of real traffic; and ensure that public health and the quality of life of residents be taken into account in the development and operation of motorway infrastructure.
