Presently, no...the perception of need for an Interstate-grade corridor down US 1 toward Rockingham just isn't there. Also, the probability of blowback from landowners in the Southern Pines region might be a political bridge too far. But, hey, this is North Carolina, so there's no telling what plans might emerge in 20 years or so, particularly if the 85-40 corridor between Charlotte & Raleigh regularly hits a "F" LOS! But even the deployment of US 1 as an interregional relief corridor would depend upon corresponding full-scale development of the US 74 corridor; and presently, I haven't heard of any solid plans to upgrade that corridor east of the Monroe bypass. Right now, with I-42 and I-87 in the mix, NC has pretty much got a full plate going; don't see much new activity happening until what's currently under development is either completed or well on the way toward such.
