Interstate 73 is a partly-realized freeway in North Carolina, running north-south along the US Route 220 corridor. The southern end spills onto surface roads in Rockingham, North Carolina, as it doesn't connect to any other freeways as of yet. From there, the highway runs north to Greensboro, North Carolina. Interstate 73 bypasses downtown Greensboro around the west side of it. It then continues north along the US Route 220 corridor toward Martinsville, Virginia, but it doesn't quite reach Virginia right now. In the future, this Interstate highway may extend southward toward the Myrtle Beach area in South Carolina, and it may extend north into Virginia as well.
My photo of an Interstate 73 marker comes from Asheboro, North Carolina, where this north-south freeway meets US Route 64 (the business route, not the bypass). US Route 64 is the main east-west drag through Asheboro, and the junction marker depicted serves eastbound travelers on that main drag. The signage is commingled with an interchange with North Carolina 49, which sits just west of the interchange with Interstate 73. Note that Interstate 73 is also combined with US Route 220 and North Carolina's Interstate 74, numbered as such because of an impossible pipe dream to connect it to the original Interstate 74 in Cincinnati, Ohio. (No page for North Carolina's Interstate 74 is included on this website, because the highway has no hope of becoming fully realized.) This photo of Interstate 73 signage was taken in April 2024, during a trip across the Delmarva Peninsula that also reached Charlotte, North Carolina.
