There's no money in NHC or Wilmington to put officers or deputies on checkpoints unless you pull them off routine patrol. Unless it's a highly visible, PR holiday event, it's likely going to be the SHP only.
This idea to start covering side roads is fantastic and long overdue. Roads like Mount Misery Road, Myrtle Grove/Masonboro Loop, and Sidbury Road are downright frightening at night because of the number of drunks using them to bypass the busy roads where they are more likely to hit a checkpoint. I was called up to Elizabethtown one night a few months ago and cut over to NC 87 on Mount Misery Road. Between Leland and Acme I had to leave the road twice because of idiots driving left-of-center. (It keeps them from having to drive on US 74/76.)
Mount Misery Road would be the FIRST place I'd throw my line in the water!
