A major motorway in Berkshire is closed both ways due to emergency works.

The M4 in Berkshire is closed in both directions between J10 (A329M/ Wokingham) and J11 (Reading) for Scottish and Southern Electricity Networks (SSEN) emergency works following the discovery of structural damage to a power line pylon near the motorway. National Highways adds: “SSEN will be attending to carry out the necessary repairs.

“Due to the extent of the damage the M4 is expected to remain closed in both directions throughout the rush hour period, into the morning of Wednesday 18th February. If this closure impacts on your planned route, please allow extra journey time.

“Plan ahead, you may wish to re-route or even delay your journey.”
