^ Another thing to note about the new bypass (which will be a fully controlled access freeway north of I-140), it will have a TOTSO movement at its junction with I-140 / NC-140. Traffic wishing to continue onto US-17 north that is following I-140 will exit onto a flyover to connect with the new bypass.
Staying straight will simply keep you on I-140/NC-140.
Same with heading southbound on the new bypass, to continue onto I-140 to bypass Wilmington, one would need to exit right, or else one will continue onto the new NC-417 (which is under construction) which is simply an arterial roadway heading into Wilmington (not freeway).
