I-74 is to continue on to the end of the US 74 Rockingham Bypass after I-73 leaves near the current NC 38 interchange. This would be around the last 2.5 miles of the Bypass which runs a total of 13 miles from north of Cordova to east of Hamlet and was opened in November 2000, costing $110 million.1
The freeway has exit numbers matching US 74's mileage which run from 319 at the NC 38 interchange to 321 at Business 74 (the map above incorrectly lists the last exit as 322), for more information go to the I-74 Exit List.
A law that passed Congress in 2012 at the request of Texas transportation officials for I-69 would allow states to sign as full interstates, routes already up to interstate standards, but not connected to another interstate. It is unknown whether NCDOT will take advantage of this law and sign this part of the Bypass as Interstate 74, however no signs had been changed by the summer of 2015.
