For more information on the county route system in New Jersey as a whole, including its history, see County routes in New Jersey.

In the 1937 renumbering of Monmouth County roads, numbers 1 through 5 were reserved for the longer, "cross-county" routes; those numbered 6 and above were to be more local in nature.

County Route 1 was designated to run from the Mercer County line via Freehold and Eatontown to the Long Branch city limits.

With the establishment of the 500 Series of county routes, CR 1 was superseded by CR 524 from the Mercer County line to Smithburg, and CR 537 from Smithburg to the Long Branch boundary.
