Just travelled along here towards Sutton Bridge and noticed that there a number of crossroads with central refuges along the way. Nothing unusual there, but what perplexed me was as I approached them there were 60mph signs which whilst unnecessary I kind of understand, the perplexing part is that they are followed by NSL signs! Perhaps Lincolnshire council have a surplus of these which they are wanting to use!
If I understand your post correctly then, the road with the centre divider would be classed as dual carriageway. The 60 mph sign would indicate a lower limit than 70 mph (for dual carriageway) and the NSL sign would indicate the lower previous speed limit ends. I assume if I understand correctly. 
There was a spate of very bad accidents along there and also a young mother was killed. That gained a lot of local press coverage so the council went onto overdrive and installed average cameras as well.
This video also gained a lot of press at the time of the death.

Thinking about it you are spot on. I obviously fell into the old two lanes = dual carriageway trap.
I thought it was a lot better when it was a 40 mph limit , all qued up behind the slowest and then when you hit that d/c just before sleaford it was like the wacky races fighting for pole position down to the r/o ,( though some did try a sly move down the left hand lane 
then from sleaford to a1 join a orderly que again bar bit of d/c before Newark
Since the limit for cars is 60 on the non-DC stretches, wouldn’t it have made more sense to leave the limit at 60 all the way?
Councils do strange stuff sometimes. Near me, they built a cycleway along the grass verge in front of about 20 houses. Each of those houses had a drive that crossed the cycleway and at each crossing, in both directions, they put up a sign. After being ridiculed in the press, they eventually took them down. God knows how much it all cost

No doubt there are legal reasons they have to show NSL signs at the end of each dual section, I should imagine it comes down to the regulations that allowed them to reduce the limit on the dual carriageways.

Spot on. NSL on a dual carriageway is 70 for cars so its a restriction at 60 no different than a 30 limit in a town.

Reminded me of this.

“A spokeswoman for Hull Council said putting 30mph signs along Freetown Way would not be allowed under the law. All roads lined with street lights carry an automatic restriction.”
This is Kings Lynn. They’ve only just got electricity and flushing toilets.
