Reader Ian Evans sent in the above video showing two lorries on fire on the A1 north of Stamford.
The fire started after the lorries collided near the Stretton junction earlier this morning. Ian was a passenger in a vehicle travelling northbound when he saw and filmed the blaze.
The southbound carriageway between the A606 and A607 is still closed while the debris is removed and the road is repaired. A diversion is in place.
