NC: Various Point Concerns Around Charlotte and along NC 16 and US 21

[Markkos1992]

I-277:  StoSt should be relabeled (also affects US 74 and NC 27)

US 21: 
1.  CatAve>-CatAve_E
2.  Consider replacing BraPlDr with Oates Rd (OatRd) to the south.
3.  MurSt>-MurRd
4.  A point should be added at Amity Hill Rd.  (signed access to I-77)
5.  US64>-US64_E
6.  CouClubRd>-CouClubDr
7.  NC1910>-CenChuRd_S. CenChuRd>-CenChuRd_N.
8.  DoeRun should probably be replaced.  DavDr probably is best left as-is.

US 21 BUS (Elkin):  ValRd>-ValDr

US 29:  NC49_E>-NC49_N

US 64: 
1.  NC90>-NC90_Tay??
2.  US21>-US21_N

US 421:  NC16>-NC16_N

US 421 BUS (Wilkesboro):  At minimum, I recommend the following:

1.  Add a point at Speedway Rd for access to North Wilkesboro Speedway.  (also affects NC 115)
2.  Make the shaping point north of NC18/268_S visible and label it DSt_E or 6thSt_N.
3.  Add a point at CBD Loop for where NC 18 SB/NC 268 WB leaves US 421 BUS NB.

NC 3:
1.  Consider replacing shaping points with visible points.
2.  WakeDr should be replaced by WinRd (Windy Rd) nearby.
3.  Consider adding a point at Roxie St (direct connection from I-85 Exit 60 SB offramp) (CouClubDr covers Copperfield Blvd IMO).

NC 10: The NC16Bus points should be S and N instead of W and E.

NC 16:
1. Consider replacing shaping points with visible points.
2.  IntWay>-IntDr
3. I think a point should be added at Charlottetowne Ave.
4. IdaDrv>-IdaDr
5.  A point should be added at the south end of the NC 16 freeway. (access to NC 273)
6. A point should be added at Rock Barn Rd.  (direct connection to I-40)
7.  WayChuRd should be slightly relocated.
8. AspDamRd>-AlsDamRd
9. Consider replacing WalLn with a nearby point. 
10. US421_E>-US421(286A)
11. NC268>-US421(286B)
12. US421BusWil>-US421Bus (optional IMO)
13. US421_W>-US421_N

NC 16 BUS (Lucia): 
1.  Consider replacing shaping points with visible points.
2.  FaiForRd>-WebRd

NC 16 BUS (Conover):  7thSt>-7thStPl (I think)

NC 18:  I recommend moving the CBDLoop to the CBDLoop/Wilkesboro Blvd intersection where the directions split.  (also affects NC 268 obviously)

NC 49:
1.  Consider replacing the shaping point north of SC/NC with a visible point.
2.  NC160>-NC160_S
3.  MooSt_E>-MorSt_E
4.  GraSt>-GraSt_N (also affects US 29)
5.  TrySt>-TrySt_S (also affects US 29)

NC 75:  The shaping point east of NC 75 is unnecessary.  The one east of OldProRd should probably be made visible somewhere.

NC 84: 
1.  WedBroDr and the shaping point east of there probably have viable replacement places for a point.
2.  GSV indicates that KeeRd has been destroyed by subdivision development.

NC 115:
1.  Should a point be added at Verhoeff Dr?  (maybe add to US 21 as well)
2.  Maybe add a point at Mount Holly-Huntersville Rd (MHHunRd). (direct access to interchange at US 21)
3.  I would change US421Bus_N to NC18/268.  Technically fine as-is though.

NC 163: Consider replacing shaping points with visible points.

NC 268: StiMeaRd>-StiMeaLn

NC 268 BUS (Elkin):  The US21Bus_S and US21Bus_N labels should be switched.

NC 273: 
1.  KeeBlvd>-KeeBlvd_W
2.  Consider replacing shaping points with visible points.
3.  I think that MainSt should be replaced with TucRd to the south.
4.  Should CarAve be removed or replaced?
