France’s traffic-information service Bison Futé issued an exceptional bulletin on 21 July warning of extensive road closures linked to the 18th and 19th stages of the Tour de France (23–24 July). The notice lists more than 30 segments of national and departmental highways that will be fully closed to all vehicles during race hours, including a 24.9 km stretch of the N85 between Aspres-lès-Corps and Laye and key alpine passes on the D1091 and D902. While domestic leisure travellers expect such disruptions, multinational companies often overlook the impact on field engineers, mobile sales staff and supply-chain movements. Several industrial plants in Grenoble and Gap rely on “just-in-time” component deliveries via the N85 corridor; logistics planners are now re-routing trucks through Italy and the A32, adding three hours to transit times. Business-aviation operators must also factor in road access: Grenoble-Alpes Isère Airport confirms that the D119 feeder road will be one-way for part of 23 July, complicating crew changes and fuel-truck movements. The bulletin advises heavy-goods vehicles to avoid the Hautes-Alpes entirely until 25 July. Companies with posted workers or expats living in the region should communicate the closures and remind staff that alternative routes may require paying additional motorway tolls or crossing into Switzerland or Italy, triggering separate vignette requirements and potential customs checks on dual-use goods. Because the Tour’s logistical footprint grows each year, mobility teams are encouraged to integrate the official Bison Futé data feed into route-planning software and to conduct a post-event review of how closures affect service-level agreements, especially for time-critical medical or tech-support call-outs.
