Traffic officers and emergency crews responded shortly after the crash, and the motorway was closed southbound to allow recovery work and ensure the area remains safe.
The M11 is a key route linking London, Essex, and Cambridgeshire, meaning even a short closure can cause heavy knock-on delays, especially during morning travel.
Where is the M11 closed and which junctions are affected?
The closure affects the southbound carriageway between:
- Junction 7 (Harlow)
- Junction 6 (M25 interchange)
Drivers heading towards London or the M25 are most likely to face delays, especially commuters and airport travellers heading in the direction of Stansted Airport connections and surrounding Essex routes.
How long will the M11 closure last?
Authorities have not confirmed an exact reopening time, but they warned the closure could last several hours.
Police investigations often take time because officers may need to inspect the scene, record evidence, and confirm whether any mechanical failure or dangerous driving played a role.
Until the overturned vehicle is removed and the road is declared safe, the motorway will remain shut.
What diversion is in place for drivers?
A diversion route has been set up for motorists travelling southbound.
Drivers are being directed away from the closed stretch and advised to follow diversion signs until they can rejoin the motorway or reach the M25 using alternative routes.
Motorists are being urged to plan ahead, allow extra time, and consider delaying travel if possible.
What are emergency services saying about the crash?
National Highways stated that the vehicle involved came to rest on its roof beside the road.
Police and emergency services remain present, managing the closure and ensuring the area stays secure.
So far, there has been no confirmed public update on injuries.
