There are delays on John Adams Way A16 reportedly caused by works in the area.
The traffic is said to be worst on the Eastbound side of the road.
The Boston Traffic Updates and News Facebook page initially reported a collision but this was denied by police.
They advised people to take alternative routes if possible.
Works are said to be taking place near to United Carpets.
