This Wednesday morning, drivers in Île-de-France are facing a challenging situation along one of the busiest routes in western Paris. The N118—a crucial artery connecting Essonne to the Hauts-de-Seine—is completely closed in both directions between Pont de Sèvres and Janvry. The culprits? Heavy snowfall and icy conditions making the road especially treacherous. The Paris Police Prefecture announced this preventive closure to prevent serious accidents.
This busy highway, daily used by thousands of drivers, runs through several municipalities including Orsay, Palaiseau, Massy, and Vélizy-Villacoublay. The complete closure of traffic on this route directly affects the daily commutes of many Île-de-France residents, as well as travel to the region's key economic hubs. It’s clear that, although disruptive, this decision is necessary to mitigate the risks posed by adverse weather conditions.
The winter weather that has affected Île-de-France since last night has led to a challenging situation on the roads. The combination of snow and has created a particularly hazardous driving environment. Authorities in the prefecture have deemed it necessary to completely close this road to allow maintenance crews to work safely and ensure the route is reopened for drivers.
In response to this closure, drivers will need to find alternate routes to reach their destinations. Roads such as the A86, the N10, and the D36 can serve as detours, but be prepared for heavy traffic on these routes, which are already quite busy. We strongly recommend checking real-time traffic apps before hitting the road. If possible, consider using public transportation options like the RER B or RER C, which connect several cities along the N118 corridor.
As of now, the police prefecture has not provided a specific reopening time. The decision will depend on weather conditions and the effectiveness of salting and snow removal efforts carried out by maintenance teams. We recommend checking the official accounts of Sytadin and the Paris Police Prefecture for the latest updates on the reopening of the route.
In short, if you absolutely need to be on the roads in the area this Wednesday, give yourself plenty of extra time, adjust your driving to winter conditions, and stay tuned to updated traffic reports. Exercise caution as winter weather continues to be unpredictable in the Paris region!
