Spur route - Citizendia

A spur route is a short road forming a branch from a longer, more important route (typically a major road, freeway, Interstate Highway or motorway). A road is an identifiable route, way or path between two or more places. The Dwight D Eisenhower National System of Interstate and Defense Highways, commonly called the Interstate Highway System (or simply the Interstate System) Motorway is a term for both a type of Road and a classification or designation A bypass or beltway is never considered a true spur route as it typically reconnects with the major road. A bypass is a Road or Highway that avoids or "bypasses" a built-up area town or village to let through Traffic flow without interference from Both loops and spurs are forms of auxiliary routes. In Road transportation, an auxiliary route is either a spur or a loop of a parent route.

Ontario

See also: 400-series highways

In the province of Ontario, most spur routes are designated as A or B, such as Highway 17A, or 7B. The 400-series highways are a network of controlled-access Freeways throughout the southern portion of the province of Ontario, Canada, forming a special A stands for "Alternate Route", and usually links a highway to a town's central core or main attraction, while B stands for "Business Route" or "Bypass", but are used when a main highway is routed around a town and away from its former alignment. The designation of "C" was used twice (Highway 3C, and 40C), and is assumed to mean "Connector". Both highways have long since been retired and are now county roads. A county highway (also county road or county route; usually abbreviated CH or CR) is a road in the United States and in the Canadian There was also one road with the D designation (Highway 8D, later the original Highway 102), and this may have stood for "Diversion", as it was along the first completed divided highway in Canada at the time (Cootes Drive in Hamilton). A dual carriageway or divided highway is a road or Highway in which the two directions of traffic are separated by a central barrier or strip of land known as a Country to "Dominion of Canada" or "Canadian Federation" or anything else please read the Talk Page Formerly known as the "Dundas Diversion" Cootes Drive is a city street in Dundas Ontario Canada (now part of the city of Hamilton) Hamilton (ˈhæməltən ( 2006 population 504559 UA population 647634 CMA population

United States

In the US, many Interstate Highways have spur routes when they enter a large metropolitan area. The Dwight D Eisenhower National System of Interstate and Defense Highways, commonly called the Interstate Highway System (or simply the Interstate System) Interstate spur routes are numbered with a three-digit number. The last two digits of the number are the number of the "parent" Interstate; e. g. a spur route of Interstate 90 would be 490, a spur route of Interstate 5 would be 805. Interstate 90 (I-90 is the longest interstate highway in the United States at nearly 3100 miles (5000 kilometers Interstate 5 (I-5 is the main Interstate highway on the West Coast of the United States, paralleling the Pacific Ocean from Canada to Mexico

Spur Interstate routes have three digit numbers with an odd first digit, while a subsidiary route either passing through a city or bypassing it would receive an even first digit. For example, in the case of Interstate 5's spur routes in Los Angeles, Interstate 405 goes through the entire city, whereas Interstate 105 ends at Los Angeles International Airport. Interstate 5 (I-5 is the main Interstate highway on the West Coast of the United States, paralleling the Pacific Ocean from Canada to Mexico Interstate 105 (abbreviated I-105, and colloquially referred to as The 105 or the one-oh-five) is an interstate highway in southern Los Angeles International Airport is the primary Airport serving Los Angeles, California, the second-most populated metropolitan area of

Spurs are also found branching from US highways, state routes, etc. The system of United States Numbered Highways (often called U State highway, state road or state route can refer to one of three related concepts two of them related to a State government in a country that is divided , often as extended onramps and offramps of expressways. An expressway is a Divided highway for high-speed traffic with at least partial Control of access.

There are many numbering violations in the spur route numbering system, thus the general rules above do not always apply.

United Kingdom

In the UK, a spur route carries the same definition, but the rules for numbering it differ.

Same-number spurs

Short spurs from primary roads or motorways typically are not given a unique number, and three arms of the junction will apparently have the same number. For example, the A14 has a same-number spur to the A1(M) motorway at Huntingdon in Cambridgeshire, the M23 motorway has one to Gatwick Airport in West Sussex and the M25 has one to Heathrow Airport. Huntingdon is a town in the county of Cambridgeshire in East Anglia, England. History Cambridgeshire is noted as the site of some of the earliest known Neolithic permanent settlement in the United Kingdom, along with sites at Fengate The M23 motorway is a Motorway in England. The Motorway runs from south of Hooley in Surrey, where it splits from the Gatwick Airport is London 's second largest Airport and the second busiest airport in the United Kingdom after Heathrow. Settlements Most settlements in West Sussex are either along the south coast or are situated in the M23 corridor To distinguish the spur on road signs, the road it leads to is usually given - for example "Gatwick Airport (A23)". The A23 road, in its original form was a major road in the United Kingdom running between London and Brighton, East Sussex.

Unique-number spurs

Typically, slightly longer spurs, or those with intermediate junctions of their own, are given unique numbers to distinguish them from their parent road. A road junction is a location where vehicular Traffic going in different directions can proceed in a controlled manner designed to minimize accidents There is a loose numbering system for these spurs on the motorway network, not dissimiliar to the US system – the road takes a three-digit number derived from that of the parent road. Examples include the M602 motorway (spur of the M60 and M62 motorways), M621 motorway (spur of the M62 and M1 motorways), and M271 motorway (spur of the M27 motorway). The M602 motorway is a relatively short motorway leading traffic into Manchester and Salford by by-passing the suburban town of Eccles. The M60 motorway is an orbital Motorway circling Greater Manchester, a Metropolitan county in North West England. The M62 motorway is a west&ndasheast trans-Pennine Motorway in northern England, connecting the cities of Liverpool and Hull The M621 motorway is a short Motorway in England. It takes traffic from the M1 and M62 motorways into Central Leeds. The M62 motorway is a west&ndasheast trans-Pennine Motorway in northern England, connecting the cities of Liverpool and Hull The M1 is a major south – north Motorway in England primarily connecting London to Leeds, where The M271 is a Motorway near Southampton in Hampshire, England. The Soviet motorway M27 connects Sochi, Tbilisi, and Baku. The M27 is a Motorway in Hampshire There are anomalous spur numbers though, for instance the M898 motorway (spur of the M8 motorway; number given to match with a unique A-number road) and the unique case of the M181 motorway, a spur of a spur. The M898 motorway is a 1 Mile (16 Km) Motorway in Renfrewshire, Scotland. The M181 Motorway links the town of Scunthorpe, England to the M180 motorway

A-road spurs do not follow a noticeable numbering system; they would be impossible to assign due to the quantity of A-road numbers in use. The Great Britain road numbering scheme is a Numbering system used to classify and identify all Roads in Great Britain.
