A1 closed at Little Ponton following accident
The A1 is closed southbound at Little Ponton following an accident.
Lincolnshire Police say they are on the scene and both carriageways are blocked. They warn drivers to expect long delays as the road could be closed for several hours.
It is believed the accident has involved two lorries.
Lincolnshire Police tweeted: "Officers dealing with the RTC at Little Ponton are asking motorists stuck in the traffic to stay in their cars and not want wander around the carriageway. We are working with Highways to clear the backlog of traffic as soon as we can."
This accident follows on from an earlier incident involving a coach and a car which closed both carriageways between Colsterworth and South Witham. One lane in each direction has since been opened.
