Grand Paris: despite the pollution, why are we still building very close to the ring road?

It is when going up the Paris ring road, from the Porte d’Italie towards the Porte de Bercy that the phenomenon is most striking. In the shadow of the Duo Towers, new buildings have sprung up like mushrooms. There, just a few meters from the 250,000 vehicles that pass on this stretch every day. And the cranes still present indicate that at least a hundred new homes are still planned there. Paris is not the only one. In Colombes (92), balconies have arisen facing the four lanes of the A86. Along the A4, in Marne-la-Vallée (77), houses are being built. In Saint-Denis (93), residents and associations are worried about a new motorway interchange coming near a school, etc.
