North Carolina's new and proposed Interstates beg for a map. Here it is. The big picture will be discussed here.
Most roads indicated by dotted lines are on the books for eventual completion.
The status of I-73 and 74 needs further elaboration. Eventually 74 should run along 77 into Virginia. Two freeway stretches of U.S. 74, around Rockingham and Laurinburg, are already posted as Future I-74. 73's status north of I-40 is uncertain. Green 85 and Green 40 were once the routings of their respective parent Interstates.
