In 1916, a system of 13 State Highways was legislated. By 1921, the number had increased to 16. 1923 laws added some more, but numbers were duplicated, with two 17's, three 18's, one 19, two 20's, and two unnumbered routes. The New Jersey State Highway Department partially solved the problem by designating 17N, 17S, 18, 18N, and 18S, but the duplication of 20's was not fixed. More unnumbered routes were added through 1926.

A partial renumbering was proposed in 1926 to eliminate duplicates and suffixes, and give every route a number. This was not adopted, but a complete renumbering was adopted in 1927 (see 1927 renumbering). Only four numbers were kept (most of 18N kept its number, and parts of 4, 5 and 8 became 4N, 5N and 8N). That system has evolved into today's system, with a partial renumbering in 1953 (see 1953 renumbering).
