Police have re-opened the A1 at Foston.
An HGV collided with the central reservation and shed its load of forklift trucks. No-one was injured as a result of the collision.
The debris from the vehicle and the shed load is on both carriageways and there is a fuel leak from the HGV. As a result, both the northbound and southbound carriageways of the A1 at Foston were closed.
Lincolnshire Police say the road was re-opened at 4pm.
However, there are still reports of tailbacks on the A1 at Grantham as a result of this accident or possibly a further accident.
The volume of traffic means that the area is very congested, and there are long delays.
Police were anticipating that the recovery of the HGV, the shed load of forklift trucks, along with the clean-up of the fuel spillage would take several hours.
