An accident was reported at 4.15pm today (Tuesday) on the M4 westbound carriageway between junction 10 at Wokingham, and junction 8/9 for Maidenhead.
One Twitter report advised people to avoid the motorway due to a “bad crash in the fast lane”.
The AA reported that one lane was closed, and congestion was building due to crash between a car and a van just before J10 for the A329(M).
