A crash between a coach full of schoolchildren and a lorry blockedthe A14 near Huntingdon this afternoon.
One lane was blocked on the A14 eastbound at junction 24, A1198 Cambridge Road at Godmanchester but has now been cleared. Residual delays remain.
Police and ambulance attended the scene and there were delays back along the A14 Spur towards Alconbury and to Brampton Hut.
The East of England Ambulance Service said multiple injuries are reported, but none appear to be serious.
A man and two children were taken to hospital as a precaution.
A police spokesman could not confirm which school the children were from, only that they were on their way back from a school trip.
The westbound carriageway was also very heavy past the scene.
