In readiness for the 2024 Olympic Games in Paris the authorities are building a new motorway junction to service the Olympic Village for athletes. However, this busy junction at Saint-Denis, north of Paris, is close to a school complex for 700 pupils. French administrative courts have just approved the project, despite the fact that, as documents seen by Mediapart show, the junction is likely to worsen air pollution in the area. Opponents meanwhile point to anti-pollution measures taken outside schools in the centre of the capital and claim that pupils in the city's rundown suburbs are being discriminated against.
