Motorists were asked to avoid the A1 northbound at Wittering this afternoon after a two car crash which left one vehicle on its roof.
A Cambridgeshire police spokesman said the crash happened at 12.05pm today (Thursday). The spokesman said there was no information about any injuries suffered at this time.
Police, fire and rescue and ambulance services all attended the scene.
An East of England Ambulance spokesman said: “We were called at 12.05pm today to a report of a car in a ditch off the A1 at Wittering.
An ambulance crew attended and assessed three patients with minor injuries who were all taken to Peterborough City Hospital for further care.”
There are long delays back to Wansford but the carriageway has now been cleared.
