Interstate 277 in North Carolina is a 4.41 mile loop in downtown Charlotte. The southern terminus Interstate 77/U.S. Highway 21 is located on the southwest side of downtown. I-277 loops around the downtown and reconnects with I-77/US 21 north of downtown. It is known by two names: the John Belk Freeway along the southern and eastern edges of downtown, and the Brookshire Freeway along the northern edge. The roadway continues past the northern terminus as North Carolina 16, which connects to Interstate 85. This is the smallest diameter for any Interstate, because I-277's junctions with I-77/US 21 are two miles apart.
