Hauliers moving goods between Switzerland and western Europe face detours this week as the Mont Blanc Tunnel shuts completely each night from 18–22 May for scheduled maintenance. Industry portal TrafficBan.com confirmed the closures run from 19:00 to 06:00 on the first night and 22:00 to 06:00 thereafter, halting all traffic in both directions.
![Mont Blanc Tunnel to close nightly 18–22 May for works, rerouting Swiss freight flows]()
If drivers suddenly need updated transit or multiple-entry visas to reroute via France, Italy, or Switzerland during the closure period, VisaHQ can streamline the paperwork in as little as 48 hours. Its online platform (https://www.visahq.com/switzerland/) lets haulage firms manage bulk Schengen applications, track status, and receive expert guidance, reducing the risk of border delays that could compound the disruption caused by the tunnel shutdowns.
Although the tunnel sits on the France–Italy border, it is an important alternative for Swiss-domiciled carriers seeking to avoid the Gotthard or Simplon routes when those axes are saturated. Forwarders report that time-critical loads such as pharma and high-value machinery often rely on Mont Blanc for overnight transits to Lyon or Turin. The maintenance is therefore expected to displace several hundred Swiss truck movements per night onto the Fréjus or Gotthard corridors, increasing the risk of early-morning congestion. Shippers have been advised to schedule departures outside the closure window or to budget extra hours for detours via the Aosta Valley or the Swiss A9–A2 axis. Customs brokers also warn that re-routing may require amending transit documents because some electronic guarantees are corridor-specific. The shutdown highlights the delicate balance of Alpine freight infrastructure, where planned works on one tunnel can ripple across multiple borders. Swiss exporters are urged to liaise closely with logistics partners and to monitor queue-length dashboards at alternative crossings throughout the week.
