Currently, NC-74 & US-52 share 'Separate' carriageways for a short distance thru the NC-65 interchange north of the major Winston-Salem Loop interchange. Since I-74 will be taking over NC-74 & overlay US-52 in this area, we need to properly fix this before label issues become a major hassle when
US-52's exit numbers convert to I-74 mileage 'soon'.
Changes to NC-74 that are needed as follows:
1) Extend the route north to north of the NC-65 interchange to the current start of the split carriageways. This is currently where
US-52 got new 'separate' Exit 119 signage, signifying it's being completely separate from Exit 117, & justifies NC-74 (I-74) carriageways are a completely separate entity from US-52's. This should IMO, become the 'new' 41 point, since the PR from the US-52 renumber says it will become this.
N.C. 74 (Winston-Salem Northern Beltway): Old Exit 119 → New Exit 41
2) Add a shaping point here to break a false multiplex with US-52 since we need a graph connection with NC-65 in #3.
3) Add in a point for the NC-65 interchange here. While, all the main ramps for it, only connect to the US-52 carriageways,
there is a single solo ramp that directly connects to NC-74, justifying a graph connection with both NC-65 & US-52 here, as the center point for it all should be the same. As for the label in NC-74's file for this interchange, we could do either
118(52) or
41B, up to you.
4) Add a shaping point here to break a false multiplex with US-52 since we need a graph connection with NC-65 in #3.
5) 'current' 41 -> 41A
Changes to US-52 as follows:
1) Add
Exit 119 for where the split with NC-74 happens. No other changes will be needed, as all the multiplex breakage points will be in NC-74's file.
Changes to NC-65 as follows:
No changes needed till I-74 comes along in this area IMO.
Changes to NC I-74FutPil:
I would recommend shortening the route to the 'new' US-52 Exit 119 point, keeping the southern ending label 'as-is' & hiding the 'NC65' label under it. Since the 'Future Interstate' files are on their death beds, this is the best option IMO till I-74 finally takes over this area and kills this file.
