If this is going to impact Future Interstates in the area at all, it would be west of I-95 towards Raleigh and the manufacturing hubs around central North Carolina. It MIGHT accelerate I-795's extension to I-40, but I doubt this will pull much from either Wilmington or Moorhead City because those ports are hamstrung by shallower depths. And it won't pull much from Hampton Roads because the main draw to/from there is either cross country or on already-existing Interstates and rail tracks that don't go to North Carolina**.
** - I'm aware of the CSX line that heads northeast from Weldon, NC to Franklin, VA, but that line A) needs some work and B) does not directly connect via CSX trackage to the Norfolk or Portsmouth terminals. That's either Norfolk Southern or short line railroads that connect to the Southside terminals. CSX only directly connects to the Newport News terminal, but from NC that would require trains to go to Richmond and loop 3/4 around the city to access the tracks.
