NC: NC 160 (and NC 49) Point Concerns

[Markkos1992]

It looks like DixRd is not applicable on NC 160 because there seems to have been a realignment here at some point.

Also BilGraPky should be changed to BilGraPkwy on both NC 160 and NC 49.

Looks like about 2011 on the realignment...

Fixes made and in the queue

I think an updates entry should have been made for the realignment of NC 160 between ByrDr and YorRd.

Also I did not catch these for NC 160 earlier:

I-485(4)>-I-485
I-77(9A)>-I-77

I saw the updates entry, but I did not see the updates to the NC 160 file.
