In the [[U.S. state]] of [[New Jersey]], the [[New Jersey Department of Transportation]] (NJDOT) maintains a system of [[state highways]]. Every significant section of roadway maintained by the state is assigned a number, officially '''State Highway Route X'''. [[Interstate Highway]]s and [[U.S. Highway]]s are included in the system. State Routes are signed with the [[circular highway shield]].

==Numbering and other details==
Major routes are typically assigned one- or two-digit numbers, except where the numbers were chosen to match an adjacent state. Most numbers from 1 to 50 follow a general [[geographic]] pattern assigned in 1927 (details below), but later additions are more haphazard. The only suffixed routes other than [[U.S. Route 9W]] are short unmarked connections such as [[New Jersey Route 76C|Route 76C]], an elongated ramp to [[Interstate 76 (Ohio–New Jersey)|Interstate 76]]. The only special state route is [[Route 33 Business (New Jersey)|Route 33 Business]]; [[U.S. Route 1 Business (Trenton)|U.S. Route 1 Business]] and [[U.S. Route 1/9 Truck (Jersey City, New Jersey)|U.S. Route 1-9 Truck]] are also present.

A statewide system of major [[county highway]]s is numbered by the NJDOT in the 500-599 range; these are known as [[500 Series County Routes (New Jersey)|500 Series County Routes]]. All counties but two&nbsp;– [[Bergen County, New Jersey|Bergen]] and [[Monmouth County, New Jersey|Monmouth]]&nbsp;– number their other county routes beginning at 600.  County routes in Bergen County range from 2 to 134; those in Monmouth County range from 1 to 57.  Ocean County also has a system of minor county routes with numbers ranging from 3 to 111 in addition to those beginning with 600.

==History==
{{Main|History of state highways in New Jersey (pre-1927)}}
The initial system of state highways was legislated in 1916, and by 1917 the state began to take over roads from the counties. By 1922, the routes were marked. [[U.S. Route]] numbers were added to some of the main routes in 1927.

{{Main|1927 New Jersey state highway renumbering}}
[[File:NJ 6 (cutout).svg|thumb|left|100px|Cutout state route marker used prior to 1953]]After a failed renumbering in 1926, a completely new numbering was instituted in 1927, with only four sections of pre-1927 routes remaining as their old numbers suffixed with N - [[Route 4N (New Jersey)|Route 4N]], [[Route 5N (New Jersey)|Route 5N]], [[Route 8N (New Jersey)|Route 8N]] and [[Route 18N (New Jersey)|Route 18N]]. The new numbers followed a general geographical pattern from north to south - 1–12 in northern New Jersey, 21-28 roughly radiating from [[Newark, New Jersey|Newark]], 29-37 from [[Trenton, New Jersey|Trenton]], 38-47 from [[Camden, New Jersey|Camden]], and 48–50 in southern New Jersey. Every state highway, even those forming parts of U.S. Routes, was assigned a number. Some short routes were assigned prefixes of S; for instance, [[Route S26 (New Jersey)|Route S26]] was a spur of [[Route 26 (New Jersey)|Route 26]] south of [[New Brunswick, New Jersey|New Brunswick]]. One prefixed and suffixed route - [[Route S4A (New Jersey)|Route S4A]] - was also defined as a second spur of [[Route 4 (New Jersey)|Route 4]]. As the system grew, some numbers beyond 50 were used, but most new routes received prefixed or suffixed labels.

{{Main|1953 New Jersey state highway renumbering}}
[[File:NJ 65 (1956).svg|100px|thumb|right|1956 state route marker]]
On January 1, 1953, the second renumbering was implemented. This was not a complete renumbering; instead, the only renumbered routes were those that violated a few guidelines&nbsp;— primarily long [[concurrency (road)|concurrencies]], especially with [[U.S. Route]]s; duplication of numbers with U.S. routes; suffixed routes; and number changes across state borders. Some routes were shortened to remove concurrencies, while others, like [[Route 25 (New Jersey)|Route 25]], completely disappeared. Numbers from 53 to 93 were assigned to renumbered routes, while shorter ones received numbers from 152 to 165. The two planned [[toll road]]s&nbsp;— the [[Garden State Parkway]] and [[New Jersey Turnpike]] - received only those names; they had been numbered [[Route 4 Parkway (New Jersey)|4 Parkway]] and [[Route 100 (New Jersey)|100]].

The majority of new numbers assigned since the 1953 renumbering have been from 166 to 185, with some short routes instead receiving numbers based on their parents (for instance, an old section of [[U.S. Route 9 in New Jersey|U.S. Route 9]] became [[Route 109 (New Jersey)|Route 109]]). Minimal disruption was caused by the assignment of [[Interstate Highway]] numbers in the late 1950s.<!--when were the numbers first chosen? Could NJDOT have known by 1953 what numbers were likely?--> In the 1990s, the majority of [[List of special routes of the United States Numbered Highway System|special U.S. Highways]] were renumbered as state routes.
