The North Carolina Highway System consists of a vast network of Interstate, United States, and state highways, managed by the North Carolina Department of Transportation. North Carolina has the second largest state maintained highway network in the United States because all roads in North Carolina are maintained by either municipalities or the state. Since counties do not maintain roads, there is no such thing as a "county road" within the state. [2] [3]

Numbering

North Carolina routes may be referred to as "North Carolina Highway x", "N.C. Highway x", "NC Route x", or just "NC x", where x is the route number. North Carolina state highways numbered under 1000 are primary state highways, [4] and numbers greater than or equal to 1000 are secondary. Nearly all secondary highways also have other names, and many primary routes are also signed with other titles.

Signage

Primary highways are marked by a black square sign in which is a white equilateral diamond shape with rounded corners that contains the route number. The diamond shape does not alter to accommodate larger route numbers; the numbers are reduced in size to fit within the diamond. Michigan is the only other state, aside from North Carolina, to have a near-identical route shield, but with pointed corners and an M in Michigan's shield. Secondary highways are not signed with route markers; small green or white signs are most commonly used to designate secondary roads. On these signs, the prefix "SR" for "secondary road" sometimes precedes the road number.

Rules and exceptions

Typically, North Carolina highway route numbers do not share numbers with any U.S. Highway or Interstate Highway in the state. If a new highway is established that would have the same number as a state highway, the state highway number usually changes. North Carolina grants exceptions to this rule in limited cases. Sometimes, as in NC 540/I-540; the two routes are given the same number because they are seen as a continuous route. Other times, as in NC 295, the number is a place holder for when the highway is eventually upgraded to an Interstate route when it meets certain standards. Finally, as in NC 73, sometimes the state, for whatever reason, does not remove a former state route designation when the Interstate is signed.

Secondary roads

According to NCDOT, the secondary road (SR) system of the state "consists of those roads maintained by the Department of Transportation that do not carry 'NC' or 'US' numbers and are outside the boundary of any incorporated municipality." [5]

Unlike highways in the primary system, secondary road numbers may be repeated multiple times throughout the system, provided that they are not repeated within the same county. For example, SR 2000 may refer to the physical roadway signed as Wake Forest Road or Falls of Neuse Road in Wake County, or it may refer to the physical roadway signed as Hickory Grove Road in Gaston County. Some road numbers are quite common. In fact, the designation SR1101 is currently used, or has in the past, been used nearly 100 times by almost every county in the state.

Secondary roads that cross a county line are generally given a new number in the new county. For example, Rustic Court is a very short road, barely one tenth of a mile in length; yet, it crosses the Durham-Orange county line. The section in Durham County (0.03 miles in length) is designated SR 2397 while the section in Orange County (0.08 miles in length) is designated SR 1604. The exception to this rule applies to roads designated SR10xx, which are generally given to regionally significant roads or roads crossing one or more county lines, but which are not part of the primary system. For example, SR 1006 (Old Stage Road), is located both in Wake and Harnett counties.

The significance of secondary road numbers is almost exclusive to NCDOT operations, generally maintenance, rather than for navigational purposes by the driving public. Certainly, the secondary road numbering system is not organized to help unfamiliar motorists find their way. Rather, this is the job of the road names, which are generally established at the local level, but which often share a sign with an SR designation for convenience. In some rural areas of the state, including parts of the Mountain and Coastal Plain regions, roads may lack a road name, in which case they are known by the SR designation.

It is not uncommon for maintenance responsibility of secondary roads to transfer from NCDOT to particular municipalities as they increase in size due to annexation. When this occurs, the SR designations are eliminated. The SR road designation is also eliminated from physical roadways that are elevated into the primary system. For example, NC 157 (Guess Road) in Durham and Person counties was once a secondary road designated SR 1008. Although it ascended into the primary system years ago, some of the old signs identifying Guess Road as SR 1008 remain.

History

North Carolina highway marker design utilized from 1949 to 1969

The original highway numbering system for North Carolina was established in the 1920s. Major routes were multiples of 10, with 10, 20, and 90 running east–west, 30, 40, 50, 70, and 80 running north–south, and 60 running as a diagonal route. [6] These cross-state routes were used as a basis for numbering the two-digit roads that served as the major city-city connectors. For example, NC 90 used to run along modern US 64, which explains the multiple "90s" that branch off US 64 today (NC 9, NC 97 and NC 98).

Three-digit numbered roads were less important spurs off the two-digit roads and often served as rural connectors. These were numbered in a scheme opposite of the U.S. and Interstate auxiliary routes; the spur routes received an extra "ones" digit instead of an extra "hundreds" digit. The first spur received the number "xx1" and the second received "xx2", where xx is the parent route number. This explains the predomination of such routes as 751, 191, 561, and the relatively few "xx0" routes (which would be the 10th assigned spur route ... few parent routes would have spurs numbered this high).

In 1933-34 many roads were renumbered to eliminate conflicts with the U.S. highways now crisscrossing the state. Some numbers (50, 90), which had become effectively U.S. routes (1 and 64 respectively) were moved or eliminated while others that conflicted with established U.S. route numbers in the state were changed to non-conflicting numbers. This seems to have been done without regard to the earlier numbering system, as were all future additions to the state highway system, which is where the modern "lack of any system" system came to be.

In 1937, several routes were renumbered to be contiguous with South Carolina routes, and in 1940 the same happened with Virginia. No effort has ever been made to match up with Tennessee or Georgia routes, but most cross-border numbered roads along this area are already U.S. highways anyway.[ citation needed ]

In 1961, the routes that conflicted with Interstates were renumbered.

Highway renumbering has since been sporadic, with most being place-holders for a future Interstate route (i.e. NC 752 and NC 295). One exception being a state law passed in 2002 swapping the highway numbers of NC 136 and NC 3; the reason was in tribute to Dale Earnhardt who died in the 2001 Daytona 500, who drove the number #3 Goodwrench Chevrolet and lived in Kannapolis.

<span class="mw-page-title-main">Exit numbers in the United States</span> Conventions on assigning numbers to highway exits in the United States

Exit numbers in the United States are assigned to freeway junctions, and are usually numbered as exits from freeways. Exit numbers generally are found above the destinations and route number(s) at the exit, as well as a sign in the gore. Exit numbers typically reset at political borders such as state lines. Some major streets also use exit numbers. Freeway exits in the United States are usually numbered in two formats: distance-based and sequential.

<span class="mw-page-title-main">Interstate 795 (North Carolina)</span> Highway in North Carolina

Interstate 795 (I-795) is a 25.49-mile (41.02 km) auxiliary Interstate Highway in the US state of North Carolina. It connects the city of Goldsboro to I-95 just south of Wilson, paralleling the northern portion of US Route 117 (US 117). The road runs a five-mile (8.0 km) concurrency with US 264 and I-587 in the last section of the route. It serves as a primary freeway spur for the city of Goldsboro to the Interstate Highway System, as well part of a major cargo route for the cities of Down East, which was a part of the impetus for its designation in 2007. Future plans call for the interstate to be further extended southward to meet I-40 near Faison.

U.S. Route 421 (US 421) is part of the United States Numbered Highway System that runs from Fort Fisher, North Carolina to Michigan City, Indiana. In the U.S. state of North Carolina, US 421 travels 328 miles (528 km) from its southern terminus at Fort Fisher to the Tennessee state line near the community of Zionville, North Carolina. US 421 traverses the state from east to west travelling from the coastal plains to Appalachian Mountains. It provides an important connection between the cities of Wilmington, Sanford, Greensboro, Winston-Salem, and Boone. Despite being signed as north–south, much of the routing of US 421 in North Carolina runs in an east–west direction, particularly between Greensboro and the Tennessee state line. Portions of US 421 have been upgraded to freeway standards including the majority of its routing between Sanford and North Wilkesboro.
