To modernize and maintain its infrastructure, the RER line B will be under construction on several sections this fall, with major interruptions scheduled for the month of November.
Of Saturday 9 to Monday 11 November included, traffic on line B will be interrupted between Denfert-Rochereau et The Berny/Robinson Crossfor maintenance and modernization operations. The stops Cité Universitaire, Gentilly, Laplace, Arcueil – Cachan, Bagneux, Bourg-la-Reine, Parc de Sceaux, Sceaux, Fontenay-aux-Roses et Robinson will therefore not be served for three days.
To compensate for this cut, two replacement bus lines will be put in place:
- Omnibus shuttle: serves stops between Denfert-Rochereau et Bourg-la-Reine.
- Direct shuttle: connects Porte d'Orléans has Berny's Crossaccessible from Denfert-Rochereau via metro line 4.
Bus lines 192, 197 and 394 will be reinforced to allow users to reach their destinations with as little impact as possible. The Orlyval shuttle, which serves Orly airport, will be suspended during this period. Travelers are invited by Ile-de-France Mobilisé (IDFM) to consult the websiteOrly whale for up-to-date information.
