I-74 enters North Carolina signed with I-77 for its first four and 1/2 miles. This segment was completed easily in April 2001 with the addition of 2 I-74 signs, one each direction to what was previously just I-77 (see eastbound photo below). Signage at the I-77 interchange, both on I-77 North and I-74 West, implies I-74 goes as far as Wytheville, Virginia, (the termination point of the route according to AASHTO) but the interstate is currently not signed north of the North Carolina border. I-74 East leaves I-77 southbound as a left exit (see below).

The only construction on this segment since it has been signed is a project to repave this section of I-77 due to let in 2012.
Comment: Virginia could sign I-74 along I-77 up to I-81 to make this southeastern portion of I-74 a true interstate Interstate. AASHTO's official I-74 route starts the interstate at the I-77/I-81 intersection east of Wytheville and then down I-77 south to North Carolina. This can wait until I-74 is signed to Winston-Salem.
