M4 - Incident

The M4 in Berkshire remains closed in both directions between J10 (A329M/Wokingham) and J11 (Reading) for emergency works by Scottish and Southern Electricity Networks (SSEN) after a nearby power line pylon was damaged by a falling tree.

Safety is our top priority. We have closed the road because of the potential risk to the structure in high winds, and the impact to road users on the M4 if the situation were to deteriorate. We are working closely with SSEN Distribution, who are securing the damaged pylon and carrying out complex repairs.

We do not have a specific timeline for when the road will reopen, but we expect it to remain closed for a considerable period while repairs continue.

We thank drivers for their patience and urge those travelling in the area to plan their journeys carefully, allow extra time where possible and follow our signed diversion routes.
