Just seen the sign warning of night closures starting on monday anybody know what the time of closure will be and the diversion route use this route quite frequently at night to and from Spalding can see it causing a few problems 
21:00. If its the usual diversion it goes up the side of the sugar refinery, straight over the next roundabout and back onto the A1 at the next northbound junction from the A1/A46 one.
The other alternative they sometimes do is that they allow you to go through the 7.5t weight limit at Coddington.
A mate has just informed me the closure is from 20:00 - 06:00 still not sure on the diversion route?
Diversion would be past British Sugar, not a massive diversion, probably will only add a few minutes on.
Correct its usually past sugar plant, left at roundabout, thru some villages, right at little services with mcdees roundabout, brings you back at a57 roundabout. If you dont get stuck behind anybody - its just as quick as a1. Follow a616 and a614.
