County routes in the U.S. state of California are controlled and maintained by the respective counties in which they are located. However, they are generally patrolled by the state's California Highway Patrol. They are typically major thoroughfares in rural areas, although many run through urban areas as well. Most are two-lane highways, and can accommodate high speeds and large volumes of traffic.

Contents

County routes are typically designated with a letter (A, B, D, E, G, J, N, R, or S, depending on the region of the state, with several counties split between two region prefixes) followed by a number (example: G2). Therefore, the county routes are sorted alphabetically, from the northernmost region of California to the southernmost region. Routes with letters (A, B, D) are in the region of Northern California, letters (E, G, J) are in Central California, and (N, R, S) are in Southern California. Routes in Lake and San Bernardino Counties are designated by numbers only.

The level of signage varies by county. In San Diego County, reassurance markers are placed as frequently as they would be on state highways. In other counties, some county routes are completely unsigned. For most county routes, signage may be found at the beginning and end and at major junctions; reassurance markers are rare and are placed at distant intervals. With a handful of exceptions (one example being S2), county routes are typically referred to by their street name (e.g. Angeles Forest Highway or Kanan Dume Road) rather than their route designation.

These routes are all part of the California Route Marker Program, which was established in 1958. This program was incorporated into the National Uniform County Route Marker Program created by the National Association of Counties in 1967. Not all counties choose to use the same marker; some have different systems of numbering their county routes. Lake County maintains 612 miles (985 km) of county roads, [1] which are not listed here.

List

The county routes are alphabetically sorted by the prefix letter in its shield, followed by the corresponding number.

<span class="mw-page-title-main">Farm-to-market road</span> Type of road in some U.S. states

In the United States, a farm-to-market road or ranch-to-market road is a state highway or county road that connects rural or agricultural areas to market towns. These are better-quality roads, usually a highway, that farmers and ranchers use to transport products to market towns or distribution centers. Historically used throughout the country, today the term is primarily associated with a large state-maintained highway system in Texas.

<span class="mw-page-title-main">Highways in Australia</span>

Highways in Australia are generally high capacity roads managed by state and territory government agencies, though Australia's federal government contributes funding for important links between capital cities and major regional centres. Prior to European settlement, the earliest needs for trade and travel were met by narrow bush tracks, used by tribes of Indigenous Australians. The formal construction of roads began in 1788, after the founding of the colony of New South Wales, and a network of three major roads across the colony emerged by the 1820s. Similar road networks were established in the other colonies of Australia. Road construction programs in the early 19th century were generally underfunded, as they were dependent on government budgets, loans, and tolls; while there was a huge increase in road usage, due to the Australian gold rushes. Local government authorities, often known as Road Boards, were therefore established to be primarily responsible for funding and undertaking road construction and maintenance. The early 1900s saw both the increasingly widespread use of motorised transportation, and the creation of state road authorities in each state, between 1913 and 1926. These authorities managed each state's road network, with the main arterial roads controlled and maintained by the state, and other roads remaining the responsibility of local governments. The federal government became involved in road funding in the 1920s, distributing funding to the states. The depression of the 1930s slowed the funding and development of the major road network until the onset on World War II. Supply roads leading to the north of the country were considered vital, resulting in the construction of Barkly, Stuart, and Eyre Highways.

<span class="mw-page-title-main">California State Route 120</span> Highway in California

State Route 120 is a state highway in the central part of California, connecting the San Joaquin Valley with the Sierra Nevada, Yosemite National Park, and the Mono Lake area. Its western terminus is at Interstate 5 in Lathrop, and its eastern terminus is at U.S. Route 6 in Benton. While the route is signed as a contiguous route through Yosemite, the portion inside the park is federally maintained and is not included in the state route logs. The portion at Tioga Pass at Yosemite's eastern boundary is the highest paved through road in the California State Route system. This part is not maintained in the winter and is usually closed during the winter season.

A routenumber, designation or abbreviation is an identifying numeric designation assigned by a highway authority to a particular stretch of roadway to distinguish it from other routes and, in many cases, also to indicate its classification, general geographical location and/or orientation. The numbers chosen may be used solely for internal administrative purposes; however, in most cases they are also displayed on roadside signage and indicated on maps.

<span class="mw-page-title-main">Business route</span> Special route connecting a major highway to a business district

A business route in the United States is a short special route that branches off a parent numbered highway at its beginning, continues through the central business district of a nearby city or town, and finally reconnects with the same parent numbered highway at the business route's end. Their designation is often intended to direct traffic to the business districts bypassed when a new highway is constructed some distance away.

<span class="mw-page-title-main">County highway</span> Type of highway

A county highway is a road in the United States and in the Canadian province of Ontario that is designated and/or maintained by the county highway department. Route numbering can be determined by each county alone, by mutual agreement among counties, or by a statewide pattern.

<span class="mw-page-title-main">Missouri supplemental route</span> Highway system

A supplemental route is a state secondary road in the U.S. state of Missouri, designated with letters. Supplemental routes were various roads within the state which the Missouri Department of Transportation was given in 1952 to maintain in addition to the regular routes, though lettered routes had been in use from at least 1932. The four types of roads designated as Routes are:

<span class="mw-page-title-main">California State Route 29</span> Highway in California

State Route 29 is a state highway in the U.S. state of California that travels from Interstate 80 in Vallejo north to State Route 20 in Upper Lake.

<span class="mw-page-title-main">Highway shield</span> Sign denoting the route number of a highway

A highway shield or route marker is a sign denoting the route number of a highway, usually in the form of a symbolic shape with the route number enclosed. As the focus of the sign, the route number is usually the sign's largest element, with other items on the sign rendered in smaller sizes or contrasting colors. Highway shields are used by travellers, commuters, and all levels of government for identifying, navigating, and organising routes within a given jurisdiction. Simplified highway shields often appear on maps.

In the U.S. state of New York, county routes exist in all 62 counties except those in the five boroughs of New York City. Most are maintained locally by county highway departments. County route designations are assigned at the county level; as a result, routes often change numbers as they cross from one county to the next due to the lack of a statewide numbering system and lack of coordination between counties. Some exceptions exist, such as County Route 36 (CR 36) in Ontario County and CR 36A in Livingston County. The assignment of routes by individual counties also results in varying system density and numbering and signage practices between the state's counties.

<span class="mw-page-title-main">Transportation in California</span> Overview of the transport in the State of California

California's transportation system is complex and dynamic. Although known for its car culture and extensive network of freeways and roads, the state also has a vast array of rail, sea, and air transport. Several subway, light rail, and commuter rail networks are found in many of the state's largest population centers. In addition, with the state's location on the West Coast of the United States, several important ports in California handle freight shipments from the Pacific Rim and beyond. A number of airports are also spread out across the state, ranging from small general aviation airports to large international hubs like Los Angeles International Airport and San Francisco International Airport.

<span class="mw-page-title-main">California postmile</span> Location marking system on highways in California, US

California uses a postmile highway location marker system on all of its state highways, including U.S. Routes and Interstate Highways. The postmile markers indicate the distance a route travels through individual counties, as opposed to milestones that indicate the distance traveled through a state. The postmile system is the only route reference system used by the California Department of Transportation (Caltrans). The system was operative by 1966.

<span class="mw-page-title-main">U.S. Route 6 in California</span> U.S. highway in California

U.S. Route 6 (US 6) is a transcontinental United States Numbered Highway, stretching from Bishop, California, in the west to Provincetown, Massachusetts, in the east. The California portion of US 6 lies in the eastern portion of the state from Bishop in the Owens Valley north to the Nevada state line in Mineral County. Prior to the 1964 state highway renumbering, US 6 extended to the Pacific Ocean in Long Beach, California, as part of the historic auto trail named the Grand Army of the Republic Highway.

In New York, a reference marker is a small green sign mounted approximately every one-tenth mile on highways maintained by the New York State Department of Transportation. This was initiated in response to the Highway Safety Act of 1966 enacted by Congress, in an effort to monitor traffic and identify high-accident locations. New York's system inventories and indexes all touring and reference routes, in addition to service and rest areas, ramps, and reservation roads.

<span class="mw-page-title-main">Business routes of Interstate 10</span> United States highway system

Interstate business routes are roads connecting a central or commercial district of a city or town with an Interstate bypass. These roads typically follow along local streets often along a former US route or state highway that had been replaced by an Interstate. Interstate business route reassurance markers are signed as either loops or spurs using a green shield shaped and numbered like the shield of the parent Interstate highway.
