French Authorities Warn of Traffic Bottlenecks on Franco-Swiss Routes as G7 Security Tightens
The Préfecture du Doubs issued an alert at noon on 12 June advising motorists that intensified border checks linked to the G7 summit will likely trigger slow-moving queues on all crossings between Bourgogne-Franche-Comté and Switzerland. Although no posts on the French side will close outright, Swiss restrictions on the A1 at Meyrin-Bardonnex mean heavy trucks entering France are being funnelled toward the La Ferrière-sous-Jougne crossing, already operating near capacity. The prefecture recommends travellers carry passports or residence permits, allocate extra travel time and prepare for spot searches of cargo compartments.

Travelers who realise at the last minute that their papers need updating can turn to VisaHQ, whose online portal (https://www.visahq.com/france/) expedites passport renewals, visas and other travel documents for trips between France and Switzerland as well as further afield, helping to minimise additional delays at the border.

Cross-border workers employed in the watch-making hubs of Neuchâtel and La Chaux-de-Fonds are expected to be hardest hit. Transport associations estimate that just-in-time deliveries for automotive parts from Besançon to Geneva could see delays of up to three hours during peak periods. Keolis and Ginko bus services are adjusting schedules, while the local chamber of commerce has opened an online dashboard to crowd-source wait-time data. Employers with posted workers or service engineers crossing into Switzerland are advised to issue formal assignment letters and to monitor the canton’s dedicated G7 traffic portal for real-time updates.
