HEAVY traffic on the M4 is still ongoing following a multi-vehicle crash on a major road this morning (January 19).

The A329(M) eastbound is partially blocked after five cars were involved in a collision around 8.30am on Berkshire Way (Coppid Beech Roundabout).

Congestion trails as far back to Junction 10 (Wokingham/Bracknell) of the M4.

And an oil spill on the M4 also meant that lanes were closed on the motorway.
