NC: US 23 ALT (Mars Hill, NC)

[Markkos1992]

This route is an adventure all of its own I think.

1.  I do not see a road at what is currently labeled NC1351.
2.  NC1506 should be OldMurRd.
3.  LauPonBRd should be shortened and slightly relocated.
4.  BearBraRd and I-26(3) need to be majorly relocated.  However, it looks like US 23 ALT may end at BearBraRd instead of going west to I-26(3).    If this change is made, then US23_S should become US23 (if not I-26(9) because I thought we may have relaxed this rule in favor of exit numbers but maybe not). (I think US 23 ALT is best left alone unless there is true evidence otherwise.)

fixes made.  I did not truncate US 23 ALT.

There is still this posting - https://goo.gl/maps/ju78iu4bNCXk3c38A

Plus there is no documentary evidence of a truncation which would make zero sense...
