A lorry driver has been taken to hospital after a crash on the Fletton Parkway which remains shut this afternoon.
The road has been shut eastbound near Hampton after two HGVs collided.
The Magpas air ambulance was called to the scene with traffic queuing back to the A1 junction and Haddon services as a result.
