A serious collision during torrential rainfall has caused chaos on the M1 motorway, forcing a full closure of the northbound carriageway and prompting the deployment of an air ambulance.
Emergency Response and Closure Details
The incident occurred on Saturday, November 29, 2025, bringing traffic to a standstill near Sheffield. National Highways confirmed the closure of the M1 northbound between Junction 34 for Meadowhall and Junction 35 for Thorpe. The severe weather conditions are believed to have been a significant factor in the crash.
Emergency services, including South Yorkshire Police, rushed to the scene to manage the situation and assist those involved. The severity of the incident was underscored by the landing of an air ambulance at the location, highlighting the serious nature of the collision.
Widespread Travel Disruption
The closure has triggered major delays on one of the country's key transport arteries. Data from Google Traffic maps illustrates the knock-on effect, with significant congestion building on several surrounding roads out of Sheffield and Rotherham as motorists seek alternative routes.
Drivers are being strongly advised to avoid the area entirely and allow for considerable extra journey time if travel in the region is essential. National Highways and emergency crews are working to clear the scene and reopen the motorway, but no estimated time for a return to normal traffic flow has been provided.
