A driver has been taken to hospital after a multi-vehicle crash on the M3.
The northbound carriageway was closed for more than two hours between junction 10 and 9 at Winchester after the incident just before 11am.
Police have said the collision involved three vehicles, while the ambulance service reported two lorries have been involved.
There were delays of up to an hour on approach, and traffic was taken off at junction 10.
A South Central Ambulance service spokeswoman said a driver was treated at the scene for ‘serious’ injuries and was taken by land ambulance to University Hospital Southampton.
An air ambulance was also called while the patient was treated.
