A significant gas leak in a disused building in Givors, near Lyon, France, has led to the closure of a major highway and the suspension of train service in the region. The A47 motorway is currently closed in both directions between Lyon and Saint-Étienne, and rail traffic on the connecting line has been halted “until further notice,” according to a statement from the Auvergne-Rhône-Alpes prefecture.
Authorities responded to the incident Saturday evening, March 14, 2026, after a large quantity of gas accumulated within the abandoned structure. The decision to close the highway and rail line was made due to the risk of explosion, and residents within a 200-meter radius of the building have been instructed to remain indoors. This disruption to key transportation routes is impacting travel throughout the Rhône department and beyond.
Emergency services, including GRDF gas technicians, a specialized unit of firefighters, and police, are currently on the scene. Gas supply to the area has been cut off, and efforts are underway to reduce gas pressure and ventilate the building. According to the prefecture, the leak has been stopped, and ventilation operations are expected to continue throughout the night.
The incident is causing significant travel delays for motorists and rail passengers. The A47 is a vital artery connecting Lyon and Saint-Étienne, and its closure is forcing drivers to seek alternative routes. The interruption of train service further compounds the transportation challenges for commuters and travelers in the region. Authorities have not yet provided an estimated timeframe for the reopening of the highway or the resumption of rail service, stating that operations will continue until it is deemed safe.
Emergency Response and Safety Measures
The prefecture has emphasized that, at present, there is no direct danger to the wider population. However, the confinement order for residents within the 200-meter radius remains in effect as a precautionary measure. GRDF technicians are working to ensure the complete removal of gas from the building and surrounding area. The specialized fire unit is equipped to handle hazardous materials and is assisting in the ventilation process. Police are maintaining a security perimeter around the site to prevent unauthorized access.
Impact on Regional Transportation
The closure of the A47 and the suspension of train service are causing widespread disruption to regional transportation networks. Motorists are advised to check traffic conditions before traveling and to consider alternative routes. Rail passengers are encouraged to contact their train operators for information on delays and cancellations. The disruption is expected to impact both local commuters and long-distance travelers.
Authorities are monitoring the situation closely and will provide updates as they become available. The priority remains the safety of residents and the swift restoration of transportation services. The prefecture will continue to coordinate with emergency services to ensure a coordinated and effective response to the gas leak.
As ventilation efforts continue overnight, officials will assess the air quality and gas levels to determine when it is safe to reopen the A47 and resume train operations. The duration of the disruption remains uncertain, but authorities are committed to resolving the situation as quickly and safely as possible.
