In 1933, NC 74 was extended north on US 21/NC 26 to Cornelius, then west as new primary routing to end at NC 271 (current NC 16) Triangle.
In 1934, NC 74 was rerouted away from Caldwell and instead over today's Davidson-Concord Rd to Davidson.
In late 1934, NC 74 was renumbered as NC 73 from Triangle to Pee Dee and NC 27 from Pee Dee to Carthage.
