a number to every route; this would have given the system numbers from 1 to 30. Instead, a total renumbering was adopted in 1927 as public law chapter 319. This system - the 1927 renumbering - assigned numbers from 1 to 12 in northern New Jersey, 21 to 28 roughly radiating from Newark, 29 to 37 from Trenton, 38 to 47 from Camden, and 48 to 50 in South Jersey. Portions of the pre-1927 routes that had been taken over or built, but were not assigned new numbers, kept their old numbers. These four routes - Route 4N, Route 5N, Route 8N and Route 18N - were all assigned the suffix N (as the only suffixed one to remain was 18N, and the others needed to be distinguished from the new routes of the same number).
