Nances, Savoie, July 27 – The A43 motorway in Savoie experienced significant disruption on Monday, July 27, 2026, after a lorry transporting vehicles caught fire. The incident, which occurred near the commune of Nances, before exit 12 towards Lake Aiguebelette in the direction of Chambéry, led to the emergency closure of the motorway and extensive traffic jams.
Emergency Response and Motorway Closure
The fire broke out on the A43 motorway, forcing an immediate closure of the fast lanes in both directions. Numerous firefighters and gendarmes were swiftly dispatched to the scene to tackle the blaze and manage the unfolding traffic chaos.
According to the prefecture, the incident happened at approximately 14:51 on Monday, July 27, 2026. The rapid response was crucial due to the nature of the lorry’s cargo, which consisted of vehicles, posing a potential risk of further escalation.
Traffic Disruption and Diversion Routes
While the A43 in the direction of Lyon has since been partially reopened, the route towards Turin remains closed at km 79, after exit 11. This prolonged closure has resulted in tens of kilometres of traffic jams on recommended alternative routes.
Motorists are advised to follow specific diversion itineraries: for cars, route S1 via the Col du Chat is recommended, while lorries should take route S3 via Les Echelles. These diversions, however, have also become heavily congested, prolonging travel times for many.
Ongoing Operations and Impact
Firefighters are still actively working on the site to fully extinguish the lorry fire and ensure the area is safe. The scale of the operation underscores the severity of the incident and its impact on one of the region’s key transport arteries.
The incident has highlighted the vulnerability of major transport routes to unforeseen events and the challenges authorities face in managing such situations effectively to minimise disruption for the public.
Wider Context: Infrastructure Challenges in Savoie
This incident comes amid broader discussions regarding infrastructure challenges in the Savoie region, including issues with the Lyon-Turin tunnel project, which has faced delays and operational difficulties. Such events underscore the critical importance of robust infrastructure and efficient emergency response systems for regional connectivity and economic activity.
Authorities continue to monitor the situation closely and will provide updates on the full reopening of the A43 motorway as soon as it is safe to do so. Motorists are urged to exercise patience and follow all official guidance regarding diversion routes.
The long-term impact on traffic flow and potential investigations into the cause of the fire are yet to be fully determined, but the immediate consequence has been a day of significant travel disruption for thousands of commuters and travellers in the Savoie region.
