M4 Eastbound Closure: A Critical Update for Wiltshire Commuters

The M4 eastbound has been closed due to a critical incident, causing significant disruption for commuters in Wiltshire. The closure was prompted by a collision that occurred in the early hours of Sunday morning, around 02:00 GMT, near Leigh Delamere Services.

National Highways has confirmed that the road will remain closed for an extended period, potentially into Sunday afternoon, as they conduct a thorough investigation. The closure affects traffic between Junction 18 (Bath) and Junction 17 (Chippenham).

To manage the situation, National Highways has released trapped traffic and implemented a diversion on the A420. Commuters are advised to plan their routes accordingly and consider alternative routes during this time.
