Four people have been killed in an eight-vehicle crash on the A34.
Four lorries and four cars were involved, also injuring 12 people, one with life-threatening injuries.
One man was flown to the John Radcliffe Hospital in Oxford by air ambulance, and two were taken by land ambulance.
The crash took place on the A34 northbound between Chieveley and West Ilsley in Berkshire. One man has been arrested on suspicion of causing death by dangerous driving.
'Motorists should avoid area'
The detained man is currently in police custody and police are appealing for witnesses to come forward.
Inspector Andy Storey said: "All motorists should avoid the area, use alternative routes and await further updates before attempting to travel on this route.
"We appreciate motorists' patience while we deal with this incident."
The fatal crash took place at 17.10 BST, and there are currently six-mile tailbacks on the northbound carriage.
The southbound carriageway was closed to allow the air ambulance to land, but has since reopened.
