It's chaos on the roads of Nantes this Wednesday, January 22, 2025. A important accident occurred early in the morning.

From 5 a.m., Bison Futé alerts on the presence of diesel on the roadway of the RN137, near Saffré, “around 20 km to the Nantes ring road”. A heavy goods vehicle accident is the cause of this leak.

As a precautionary measure, Bison Futé then announced a speed limit of 90 km/h, the road being “very slippery”. A measure which did not prevent excess accidents. At 5:53 a.m., the real-time traffic information site “several accidents linked to slippery roads”. Therefore, the RN137 was cut at the Treillières interchange.

A diversion in place

The Interdepartmental Directorate of Western Roads (DirO) has set up a DETOUR. So, you have to exit at the Grande Haie interchange towards Treillières and continue on the RD537 to Ragon to find the RN137 and the Nantes ring road.

“The speed is limited to 90 km/h on the upstream section between Saffré and Treillières. »

In the direction of Nantes towards Rennes, the left lane is neutralized and the speed limited to 90 km/h at Saffré following damage caused to the safety barriers.

Firefighters on site

At 6:31 a.m., the Loire-Atlantique firefighters were dispatched to the RN137, near the town of Orvault for “a pileup concerning two heavy goods vehicles, four cars and a motorcycle » following the presence of hydrocarbon released earlier in the night.

At 9 a.m., firefighters were still on site. This time the balance sheet amounts to seven cars and always two heavyweights (a flatbed truck and a parcel transporter truck).

Two accidents on public roads “minors” also took place before this pileup.

An important system has been deployed with 41 firefighters, 23 machines, a drone pilot and a dog technical team. A command group has been set up as well as road rescue and personal rescue resources.

“The death toll is ongoing,” specifies the Operational Intervention and Rescue Center (Codis).
