The Centre National d’Information Routière (CNIR), Rosny-sous-Bois, has informed us that in order to reduce noise pollution at night, the A6b motorway (through Gentilly and Kremlin-Bicêtre) will be closed indefinitely to goods vehicles of over 3.5t travelling outwards from Paris every night between 22h00 and 06h00 from 4 November 2004. Vehicles will be diverted via the A6a motorway (Porte de Gentilly).
