A pedestrian has been killed after being hit by a lorry on the M4 in the early hours of Tuesday morning.
Part of the M4 was closed following the collision, which police were called to at 2.57am.
Police have not yet released any details on the age or name of the person killed.
The pedestrian died at the scene and the lorry driver was not injured.
Thames Valley Police said: “We were called at 2.57am to reports that a lorry had collided with a pedestrian on the M4 eastbound between Junctions 11 and 12.
“The pedestrian died at the scene. The lorry driver is uninjured but suffering from shock.”
The eastbound carriageway and one lane on the westbound carriageway were closed on Tuesday morning following the incident.
Commuters faced long delays on Tuesday as the closures remained in place for most of the morning.
Highways England announced shortly before 11am that the westbound carriageway had opened.
The eastbound carriageway opened a short while later, with Highways England saying the “long delays are clearing”.
