Termini
In March 2003, The state DOT rerouted the west end of NC 24 from US 74 to Interstate 77 (Exit 18). This was facilitated by following Harris Boulevard in east Charlotte instead of following NC 27. This added nearly 15 miles (24 km) onto the highway's length. On December 8, 2008, Interstate 485 opened in Northwest Mecklenburg County; at that same time NC 24 was extended again by 1 mile (1.6 km) to the new freeway (Exit 21) along West WT Harris Boulevard.
Before this rerouting, NC 24 was extraneous west of Johnsonville. It was concurrent with NC 27 over its entire length to its terminus at U.S. 74, at which point NC 27 continued while NC 24 did not.
NC 24's eastern terminus is at US 70 in Morehead City. This eastern segment leading to the terminus provides access to communities on the mainland side of the Bogue Sound.
