A car transporter overturned on the A34 in Berkshire, causing long delays for motorists.
The lorry crashed on the northbound carriageway near East Ilsley, shortly before 08:30 GMT.
Police closed the road northbound from the M4 at Chieveley, diverting traffic via Wantage. One lane of the southbound carriageway was also closed.
The Highways Agency said the road was not expected to reopen fully until about 22:00.

Motorists were being advised to plan for longer journey times and find alternative routes.
The transporter was fully laden, carrying seven vans, many of which were strewn across the carriageway.

"Additionally, repairs will have to be carried out to the central reservation before the carriageways can be reopened."
