Update: A46 Caistor closure
Police have said the road will be closed for some time and diversions are now in place.
Traffic from Grimsby is currently being diverted at the A1084/B1225 junction, and from Market Rasen access to Caistor is currently available via Nettleton Road.
A police spokesman said: “Please don’t try to use the A46 Caistor bypass between those junctions as you will hinder the emergency services working on scene.
“This is likely to be extended further afield once full diversions are implemented.”
