From north to south the highway traverses South West Queensland and the North West Slopes , Orana , and Central West regions of New South Wales . The highway is part of the Great Inland Way linking Sydney and Cairns , and provides all-weather access to rugged black opal country of Lightning Ridge . Castlereagh Highway
142-677: A national highway in New South Wales (NSW), Australia . It provides the major road link between southeastern Queensland and Victoria via central NSW and as such carries large amounts of freight. At 1,058 kilometres (657 mi) in length, the Newell is the longest highway in NSW, and passes through fifteen local government areas . The highway is named in honour of H. H. Newell, the first Commissioner for Main Roads in New South Wales (1932–1941). It
213-646: A "highway" as only a way open for use by motor vehicles, but the California Supreme Court has held that "the definition of 'highway' in the Vehicle Code is used for special purposes of that act" and that canals of the Los Angeles neighborhood of Venice are "highways" that are entitled to be maintained with state highway funds. Large scale highway systems developed in the 20th century as automobile usage increased. The first United States limited-access road
284-683: A collection of unrelated roads, many gazetted as separate entities. The passing of the Main Roads Act of 1924 through the Parliament of New South Wales provided for the declaration of Main Roads, roads partially funded by the State government through the Main Roads Board (later Transport for NSW ). Main Road No. 6 was declared as part of Mid-Western Highway from West Wyalong and Marsden, Main Road No. 11
355-802: A five-year period." A 2021 study found that areas that obtained access to a new highway experienced a substantial increase in top-income taxpayers and a decline in low-income taxpayers. Highways also contributed to job and residential urban sprawl. Highways are extended linear sources of pollution . Roadway noise increases with operating speed so major highways generate more noise than arterial streets. Therefore, considerable noise health effects are expected from highway systems. Noise mitigation strategies exist to reduce sound levels at nearby sensitive receptors . The idea that highway design could be influenced by acoustical engineering considerations first arose about 1973. Air quality issues: Highways may contribute fewer emissions than arterials carrying
426-403: A highway available to vehicles is also available to foot or horse traffic, a highway available to horse traffic is available to cyclists and pedestrians; but there are exceptional cases in which a highway is only available to vehicles, or is subdivided into dedicated parallel sections for different users. A highway can share ground with a private right of way for which full use is not available to
497-438: A highway. Recent examples include toll bridges and tunnels which have the definition of highway imposed upon them (in a legal order applying only to the individual structure) to allow application of most traffic laws to those using them but without causing all of the general obligations or rights of use otherwise applicable to a highway. Limited access highways for vehicles, with their own traffic rules, are called "motorways" in
568-560: A number of similarly worded definitions such as "a way over which all members of the public have the right to pass and repass without hindrance" usually accompanied by "at all times"; ownership of the ground is for most purposes irrelevant, thus the term encompasses all such ways from the widest trunk roads in public ownership to the narrowest footpath providing unlimited pedestrian access over private land. A highway might be open to all forms of lawful land traffic (e.g. vehicular, horse, pedestrian) or limited to specific modes of traffic; usually
639-409: A public highway is also known as " The King's Highway ". The core definition of a highway is modified in various legislation for a number of purposes but only for the specific matters dealt with in each such piece of legislation. This is typically in the case of bridges, tunnels and other structures whose ownership, mode of use or availability would otherwise exclude them from the general definition of
710-632: A public road is not included in the relevant statistics. The United States has the world's largest network of highways, including both the Interstate Highway System and the United States Numbered Highway System . At least one of these networks is present in every state and they interconnect most major cities. It is also the world's most expensive mega-project, as the entirety of the Interstate Highway System
781-494: A result. State Highway 17 was named Newell Highway on 2 July 1941, in honour of H. H. Newell, Commissioner for Main Roads 1932–41, following his death in office. At the time of the gazettal of State Highway 17, it followed existing roads as far as possible, but between Coonabarabran and Narrabri and between Narrandera and West Wyalong no road existed. The section through the Pilliga Scrub between Coonabarabran and Narrabri

Congestion is considered a negative externality by economists. A 2016 study found that for the United States, "a 10% increase in a region's stock of highways causes a 1.7% increase in regional patenting over

In transport, demand can be measured in numbers of journeys made or in total distance travelled across all journeys (e.g. passenger-kilometres for public transport or vehicle-kilometres of travel (VKT) for private transport ). Supply is considered to be a measure of capacity. The price of the good (travel)

From its northern terminus at Goondiwindi in Queensland, where it meets the Cunningham and Leichhardt Highways , and forms the southward extension of Cunningham Highway from Warwick and Brisbane, the Newell runs south across the Queensland-New South Wales border through Boggabilla , Moree , Narrabri , Coonabarabran , Gilgandra , Dubbo , Parkes , Forbes , West Wyalong , Narrandera , Jerilderie , and Finley . Its southern terminus
1065-805: Is located entirely west of the Great Dividing Range , running largely along the foot of the western slopes of the range, and as such crosses nine major rivers, all west-flowing from the Great Dividing Range. From north to south these rivers are the Macintyre (at Goondiwindi), the Gwydir (10 km north of Moree), the Mehi (at Moree), the Namoi (near Narrabri), the Castlereagh (at Coonabarabran and again at Gilgandra),

The effect of increases in supply (capacity) are of particular interest in transport economics (see induced demand ), as the potential environmental consequences are significant (see externalities below). In addition to providing benefits to their users, transport networks impose both positive and negative externalities on non-users. The consideration of these externalities—particularly

#17328558542711562-419: The 1920s and 1930s, many nations began investing heavily in highway systems in an effort to spur commerce and bolster national defence. Major highways that connect cities in populous developed and developing countries usually incorporate features intended to enhance the road's capacity, efficiency, and safety to various degrees. Such features include a reduction in the number of locations for user access ,

What is defined in England as a highway will often in Scotland be what is defined by s.151 Roads (Scotland) Act 1984 (but only "in this act" although other legislation could imitate) simply as a road , that is: The word highway is itself no longer a statutory expression in Scots law but remains in common law. In American law,

Everyday use normally implies roads, while the legal use covers any route or path with a public right of access, including footpaths etc. The term has led to several related derived terms, including highway system , highway code , highway patrol and highwayman . Major highways are often named and numbered by
1917-540: The United States, it is also used as an equivalent term to controlled-access highway , or a translation for motorway , Autobahn , autostrada , autoroute , etc. According to Merriam-Webster , the use of the term predates the 12th century. According to Etymonline , "high" is in the sense of "main". In North American and Australian English , major roads such as controlled-access highways or arterial roads are often state highways (Canada: provincial highways ). Other roads may be designated " county highways " in

The status of highway on most older roads has been gained by established public use, while newer roads are typically dedicated as highways from the time they are adopted (taken into the care and control of a council or other public authority). In England and Wales,

Australia's Highway 1 is the longest national highway in the world at over 14,500 kilometres (9,000 mi) and runs almost the entire way around the continent. China has the world's largest network of highways, followed closely by the United States. Some highways, like the Pan-American Highway or the European routes , span multiple countries. Some major highway routes include ferry services, such as US Route 10 , which crosses Lake Michigan . Traditionally highways were used by people on foot or on horses . Later they also accommodated carriages , bicycles and eventually motor cars , facilitated by advancements in road construction . In

At one point in the Riverina region of NSW, the highway carries approximately 1,900 vehicles daily, of which about 32 per cent is heavy vehicles; while at another point in the north of the state, which carries the largest number of heavy vehicles, on average a truck passes every 60 seconds, 24 hours a day, 7 days a week. The speed limit on most rural sections of the highway is 110 km/h (68 mph). Before its declaration, Newell Highway existed as

In Dubbo , the largest urban centre through which the highway passes, average daily traffic volumes are in the order of 20,000 vehicles a day. Many heavy vehicles use the Newell Highway – between 26 per cent and 52 per cent of all traffic, depending on the point along

High-occupancy vehicle lanes are being added to some newer/reconstructed highways in the United States and other countries around the world to encourage carpooling and mass transit. These lanes help reduce the number of cars on the highway and thus reduces pollution and traffic congestion by promoting
3337-659: The planning stage, this extra traffic may lead to the new road becoming congested sooner than would otherwise be anticipated by considering increases in vehicle ownership. More roads allow drivers to use their cars when otherwise alternatives may have been sought, or the journey may not have been made, which can mean that a new road brings only short-term mitigation of traffic congestion. Where highways are created through existing communities, there can be reduced community cohesion and more difficult local access. Consequently, property values have decreased in many cutoff neighborhoods, leading to decreased housing quality over time. Mostly in

3621-634: The same vehicle volumes. This is because high, constant-speed operation creates an emissions reduction compared to vehicular flows with stops and starts. However, concentrations of air pollutants near highways may be higher due to increased traffic volumes. Therefore, the risk of exposure to elevated levels of air pollutants from a highway may be considerable, and further magnified when highways have traffic congestion . New highways can also cause habitat fragmentation , encourage urban sprawl and allow human intrusion into previously untouched areas, as well as (counterintuitively) increasing congestion, by increasing

These features are typically present on highways built as motorways ( freeways ). The general legal definition deals with right of use, not the form of construction; this is distinct from e.g. the popular use of the word in the US. A highway is defined in English common law by
4118-445: The use of carpooling in order to be able to use these lanes. However, they tend to require dedicated lanes on a highway, which makes them difficult to construct in dense urban areas where they are the most effective. To address habitat fragmentation, wildlife crossings have become increasingly popular in many countries. Wildlife crossings allow animals to safely cross human-made barriers like highways. Road traffic safety describes

The first section of motorway in the UK opened in 1958 (part of the M6 motorway) and then in 1959 the first section of the M1 motorway . Often reducing travel times relative to city or town streets, highways with limited access and grade separation can create increased opportunities for people to travel for business, trade or pleasure and also provide trade routes for goods. Highways can reduce commute and other travel time but additional road capacity can also release latent traffic demand . If not accurately predicted at
4260-456: The word "highway" is sometimes used to denote any public way used for travel, whether a "road, street, and parkway"; however, in practical and useful meaning, a "highway" is a major and significant, well-constructed road that is capable of carrying reasonably heavy to extremely heavy traffic. Highways generally have a route number designated by the state and federal departments of transportation. California Vehicle Code, Sections 360, 590, define
