A man has died after he fell from a bridge of the M4 motorway today.
The incident happened at around 10.30am, between junctions 17 and 18.

The eastbound carriageway is unaffected and remains open.
A police spokesperson said: “We have closed the westbound carriageway of the M4 near to junction 18 following reports that a man has jumped or fallen from a bridge over the motorway. The man has sadly died at the scene.”
