NC: US 501 Minor Point Errors

[Markkos1992]

The Top 5 are on US 501 north of I-85.

1.    BosRd needs to be relocated.
2.   US158 should be US158_E.
3.   RobBraRd should be RobyBarRd.  (also affects NC 57)
4.   NC57 should be NC57_S.
5.   I would change RedMntRd to RedMouRd.

6.  NC54 should be NC54_E. (also affects US 15)

Exit numbers should be added for the US 15/US 501 freeway portion south of I-85 and the US 1/US 15/US 501 Concurrency for US 15 and US 501
