A section of the M4 near Bristol is likely to be closed for most of the day after one person died in a motorway crash.
The road was closed after the incident between junctions 21 and 20, near the Almondsbury Interchange.
The accident involved two lorries and a car.
Police say the road will be closed for a "significant" part of the day.
They are asking motorists to avoid the area and said the M49 should be used as an alternative.
Great Western Ambulance said the lorry driver was pronounced dead at the scene.
Jill Risdale from the Highways Agency said there were "long tailbacks" in the area.
She said motorists should "avoid the area completely at the moment".
Traffic is queuing back as far as the toll booths on the Welsh side of the Second Severn Crossing.
