A2:Concurrency broken with A5 and E16 in Derry b/n B507_S and A5. I think you've extended A5/E16 over the bridge to A40 but A5 misses this wp. All wps need to be renamed.
Concurrency broken with A11 in Belfast b/n A6 and A24
B1:If two named cross roads have different names but would have identical labels (Milford Parkway & Millville Parkway both would be MilPkwy), either add a 4th letter to a 3-letter part of one of the labels, or choose 3 different letters for that label.
BalRd_N = Ballee Road -> BalRd

B2Cam:DruRd_E -> CarnRd (according to GM)
A3 needs a wp to match B2 wp "DruRd"
B2Cam itself needs another wp @

B52 and B181_N might be split but I'd leave them as-is since they almost overlap (sat view)

B23:DruRd is off, I would position it between both "junctions" which is virtually one junction:

B34/B131/B196:OSM suggests that B34 extends at east end to B131/B196 junction.
GSV could be interpreted that B34 just extends to the junction west of the B131/B196 junction and that the section in-between is B196 or B131. The parallel road should be B196 too.
I would go with OSM if you don't have an official source.
B34:BovRd is indicated being a B106 branch according to OSM and GSV
A29 -> A29/A45
B35:KilRd_E -> KilRd
KilRd_W -> KinRd or KicRd
A4 -> A4/A45
B36:EshRd source? OSM inidcates Drumshancorick Road
B38:Split B101 into 2 wps
B39:A11: OSM and GM suggests it being B126; GSV 2008-2018 just indicates "(A12)" and "(M1)"
Is B39 really concurrent to A52 here? If it's not signed, I would split the route.
OSM shows a B39 branch off A52 at A52_W junction but I cannot find anything on GSV
A52_W wp needs to be split into 2 wps if the B39 branch exists. If not, the wp should be at the western junction
OldBalRd should be moved a little bit because it's virtually one junction (overlapping)
