Yeah, in my experience North Carolina has handled its work zones better than South Carolina.
Currently, approximately 50 miles are or will soon be under construction between I-74 and I-40, excluding the Fayetteville "bypass" portion between either end of US-301.
Hopefully, funding can be found to close the "gap" around Fayetteville, where the highway will reduce from 8 to 4 lanes both north and south of the city, along with more 6 to 8 lane widening north of I-40 up towards Smithfield.
The portion north of Smithfield was just recently reconstructed with the mainline section reconstructed with new pavement and a modern concrete median barrier. The interchanges and existing 1950-era bridges are planned to soon be replaced as well, fully modernizing that stretch. It has all been designed with the capability of being expanded to an additional 2 lanes in each direction to the outside in the future.
North of US-301 / Kenly is a less traffic portion, though still warrants 6 lanes during peak travel periods.
South Carolina is planning to widen I-95 north of Florence to the North Carolina state line to 6 lanes I believe, and North Carolina should next be planning the section between I-74 and the South Carolina state line (13 miles). That, in combination with an expanded Fayetteville bypass, north of I-40 to Kenly, and the existing 50 miles under construction, would create approximately 145 miles of continuous 6 to 8-lane interstate highway between I-20 and Kenly. This is all achievable in the next 10 years if funding is allocated properly. It would alleviate the worst parts of I-95, leaving only a gap in the less traveled portion between Kenly and VA I-295, and then of course south of I-20 to US-17 in SC (where 33 miles south of there to Georgia is planned).
