If you are landing at Charles-de-Gaulle or Orly today, brace for a patchwork of rail interruptions. The RATP and SNCF are running an unprecedented combined operations plan that meshes annual summer engineering shutdowns with security-driven closures for the Tour de France’s arrival. • Metro and RER: From first service this morning Line 1 skipped seven central stations including Concorde and Charles-de-Gaulle-Étoile, while Line 2 began running non-stop between Pigalle and Victor-Hugo from 13:00. The Montmartre funicular was also suspended. On the RER network, the central trunk of Line B—gateway to CDG Airport—closed yesterday evening and remains shut between Gare du Nord and Bourg-la-Reine until 6 August for switch-replacement. Replacement buses start outside Porte d’Orléans; airport-bound passengers are advised to use Line E to Saint-Lazare and Metro 14 to Châtelet. • Surface transport and last-mile impact: More than 25 bus lines are on diversion around the Champs-Élysées security perimeter until 23:00, and ride-hail pick-ups are prohibited on Avenue des Champs-Élysées, Rue de Rivoli and Place de la Concorde. Logistics providers have been asked to reschedule non-essential deliveries after 22:00. • Engineering context: The heavy rail works form part of Île-de-France Mobilités’ €730 million “Grand Travaux d’Été 2026” programme. Over three weeks contractors will replace 40 points on Line B, refurbish tunnels on Line D and re-signal parts of the RER C corridor to Orly. The agency estimates that 110 000 daily airport passengers will need to alter itineraries. Practical advice for employers: 1) inform travellers to download the Île-de-France Mobilités app for dynamic rerouting; 2) encourage e-ticketing or contactless payments—ticket counters at affected stations are closed; 3) consider arranging private shuttles for late-night flights as rail alternatives thin out after 22:30. Immigration queues at CDG have so far remained stable because most long-haul arrivals are scheduled after the race. The next critical milestone will be 7 August, when a second construction phase further disrupts RER B south of Paris. Mobility managers with August assignees should pre-book taxi vouchers or adapt lease start dates accordingly.
