A16 shut between Pinchbeck and Surfleet - causing delays throughout Spalding
The A16 is shut between Pinchbeck and Surfleet, with motorists reporting big tailbacks.
The road is closed between Wardentree Lane and the A152 following a collision that was reported to police just before 2.30pm.
Traffic is reportedly heavy throughout Surfleet, Pinchbeck and Spalding town centre - as well as on the A16 and A151 - with motorists being diverted through the town and villages.
Police have described it as a 'serious collision' involving a car and a crane. The condition of the occupants is not yet known.
The AA is also reporting severe delays on the A17 this afternoon. These are said to be as a result of 'holiday traffic' as well as the closure of the stretch of the A16.
It estimates that traffic is taking about 40 minutes to travel between Sutterton Roundabout and Peppermint Roundabout.
