Highway systems by country


This article describes the highway systems available in selected countries.

Albania

In Albania, major cities are linked with either new single/dual carriageways or well maintained State Roads marked as "SH".
There is a dual carriageway connecting the port city of Durrës with Tirana, Vlorë, and partially Kukës.
There are three official Motorway segments in Albania marked with an "A" :
Thumanë–Milot–Rrëshen–Kalimash,
Levan–Vlorë,
and partly Tirane–Elbasan.
Most rural segments continue to remain in bad conditions as their reconstruction has only begun in the late 2000s by the Albanian Development Fund .

Algeria

About 1390 km of highways in Algeria are in service and another 1500 km are under construction.

Australia

In Australia, a highway is a distinct type of road from freeways, expressways, and motorways. The word highway is generally used to mean major roads connecting large cities, towns and different parts of metropolitan areas. Metropolitan highways often have traffic lights at intersections, and rural highways usually have only one lane in each direction. The words freeway, expressway or motorway are generally reserved for the most arterial routes, usually with grade-separated intersections and usually significantly straightened and widened to a minimum of four lanes. The term motorway is used in some Australian cities to refer to freeways that have been allocated a metropolitan route number. Roads may be part-highway and part-freeway until they are fully upgraded. The Cahill expressway is the only "named" expressway in New South Wales, which opened in 1954, the first in the region.

Austria

In contrast to Germany, according to a 2002 amendment of the Austrian federal road act, Bundesstraßen is the official term referring only to autobahns and limited-access roads. The administration of all other former federal highways has passed to the federal states.
Therefore, officially classified as Landesstraßen, they are still colloquially called Bundesstraßen and have retained their 'B' designation, followed by the number and a name. They are marked by a blue number sign.

Belgium

Belgium has the second highest density highway network in Europe after the Netherlands, at 54.7 km per 1000 km². Most Belgian highways have three lanes with a few exceptions like the ring roads around Brussels and Antwerp which have five or six lanes in some stretches. Belgium is situated at a crossroads of several countries, and its highways are used by many nationalities. Belgian highways are indicated by the letter "A" and a European number, with E numbers being used most often. Roads that are a ring road around a city or a town are usually indicated by an R number. Many of the highways in Belgium are illuminated at night, since there is a surplus of nuclear-powered electricity during off-peak hours.

Bosnia and Herzegovina

As for Bosnia and Herzegovina, the Pan-European Corridor Vc Motorway, Budapest–Osijek–Sarajevo–Ploče, is one of the most significant and project of the highest priority; in Bosnia and Herzegovina it coincides with A1 Motorway. The construction works on the road have already begun, but intensified beginning of the construction will be a key starter of economic and social activities, and will enable Bosnia and Herzegovina to be connected to main European traffic network, as well as to global European economic and social structure.
Construction of the motorway, whose total length is 340 km, will provide: rational connecting to neighboring countries and regions; stabilizing and developing effects will be reached; transport conditions and quality of life improvement; economy competitiveness enhancement; new projects launched and national and international private investments enhancement.

Botswana

Brazil

In Brazil, highways are named "rodovia", and Brazilian highways are divided in two types: regional highways and national highways. In Brazil, rodovia is the name given exclusively to roads connecting two or more cities with a sizable distance separating the extremes of the highway. Urban highways for commuting are uncommon in Brazil, and when they are present, they receive different names, depending on the region. Very rarely names other than "rodovia" are used.
Regional highways are named YY-XXX, where YY is the abbreviation of the state where the highway is running in and XXX is a number.
National highways are named BR-XXX. National highways connects multiples states altogether, are of major importance to the national economy and/or connects Brazil to another country. The meaning of the numbers are:
Often, Brazilian highways receive names on top of their YY/BR-XXX designation.

Bulgaria

The strategic location of the country on the Balkan Peninsula is decisive for the fact that 4 out of 10 land Pan-European corridors run through it, and 10 European routes - 6 A-class and 4 B-class routes.
Highways in Bulgaria are dual carriageways, grade separated with controlled-access, designed for high speeds. In 2012 legislation amendments defined two types of highways: motorways and expressways. The main differences are that motorways have emergency lanes and the maximum allowed speed limit is 140 km/h, while expressways don't and the speed limit is 120 km/h.
As of December 2018, of motorways are in service, with another being under various stages of construction. More than of motorways are planned. Also, several expressways are planned.

Canada

Since the Trans-Canada Highway is not yet a divided, multi-lane freeway for its entire length, the section that crosses the western provinces and northern Ontario is considered to be more of an equivalent to the U.S. Route highway network in the neighboring United States. southern Ontario's 400-series freeways, Quebec's autoroutes, New Brunswick's portion of the Trans-Canada, Nova Scotia's 100-series highways, Alberta's Ring Road system, and Saskatchewan's Ring Road system are provincial equivalents to the American Interstate Highway System. The Canadian freeways interconnect with each other across provincial lines, and also with the American Interstate system. For example, freeways in Québec connect Montreal with the American border, and thence Interstate 87 continues from there to New York City, and likewise, Toronto is connected to the border by Ontario freeways, and thence by Interstate 190 to Buffalo, New York.

Chile

Chile has a large highway coverage which connects the whole country with the exception of the Magallanes region.

China, People's Republic

"Highways" in China, more often than not, refer to China National Highways. The fully controlled-access, multi-lane, divided routes are instead called expressways., there were 5.98 million km of highways and 131,000 km of expressways in China; both total lengths are the longest in the world.
In Mainland China, private companies reimbursed through tolls are the primary means of creating and financing the National Trunk Highway System.
Expressways are lumped with first-grade G-prefixed guódào or A-prefixed first-grade expressways in major municipal cities. All roads in the NTHS and most A-prefixed roads are expressways.
Some highways are numbered with a leading zero.
The term Freeway during the 1990s was used on a few expressways. The term freeway has since been replaced with expressway on all signs in China. The Chinese name for expressways is 高速公路; in pinyin, it is gāosù gōnglù, which literally means "high speed public road".
Signs on the National Highways are green, while on the lower-grade highways and urban expressways are blue.

Hong Kong

In Hong Kong, the type of high speed roads is referred to as expressway, but some are named as highways or roads. Some others are named corridors and bypasses.

Colombia

In Colombia are managed by the Colombian Ministry of Transport through the National Institute of Roads. Colombia's road infrastructure is still very underdeveloped with most of the highways presenting a two lane road for outbound and inbound traffic. Some exceptions are the Autopista Norte, linking Bogota and the towns of Tunja and Sogamoso and the Highways of the Valle del Cauca, an infrastructure improvement project started about a decade ago which has not yet been entirely finished. Several dual-carriage ways also link cities like Medellin, Pereira, Manizales and Armenia.
Nowadays, the direct public funding on highways is increasing, focused mostly in connecting Colombia's agricultural and industrial heartland with its Caribbean and Pacific ports through twinning existing roads and the construction of 5,892 km of roads.
The most important projects under negotiation or construction are La Ruta del Sol, a 4-lane highway between Bogota and the Caribbean coast; and the Highway between Bogota and Buenaventura which includes a 9 km tunnel.

Croatia

Croatia has 11 highways and 13 expressways. The earliest highway in Croatia was built in 1971. The word highway is a common Croatian translation of the term autocesta, which describes a toll highway similar to a freeway or an Autobahn.

Czech Republic

The Czech Republic has 17 motorways. The construction of the earliest Czech highway between Prague and Brno was initiated in 1939, but was twice interrupted and reached Brno only in 1980. The word highway is a common Czech translation of the term dálnice, which describes a toll highway similar to a freeway or an Autobahn.

Denmark

With the completion of the extremely long highway bridge-tunnels of Great Belt Fixed Link in 1998 and Øresund Bridge in 2000, continental Europe was finally connected by road and rail with capital city Copenhagen and Sweden. This includes the Swedish highway and railroad system. The bridge-tunnels are all interconnected with major Danish highways and completes a continuous international road connection from northern Sweden to Gibraltar at the southern edge of Spain and Messina, Italy, at the southern tip of the Italian "boot".
The 18 kilometre Fehmarn Belt Fixed Link has commenced construction in 2017, planning to link Zealand to northern Germany by 2028.

Finland

The national highways in Finland are numbered 1-29 and are in total 9,000 km long. This number system originates from 1938. There are motorways for 881 kilometres around the largest cities, specially down south near the capital Helsinki. Highways numbered 1-6 are the main connection roads in Finland.

France

France has a national highway system dating back to Louis XV. The chaussées constructed at this time, radiating out from Paris, form the basis for the "routes nationales", whose red numbers differ from the yellow numbering used for secondary "routes departementales". The RNs numbered from 1 to 20 radiate from Paris to major ports or border crossings. More recently, France has constructed Autoroutes, ex. A6-A7 which is called "Autoroute du Soleil", superhighways with a speed limit of 130 km/h.

Germany

Aside from highways bearing the Autobahn designation, Germany has many two- and four-lane roads. Federal highways not known as autobahnen are called Bundesstraßen and, while usually two-lane roads, they may also be four-lane, limited-access expressways of local or regional importance. Unlike the Autobahnen, though, Bundesstraßen mostly have speed limits.

Greece

Hungary

has 7 major motorways :
Also, there are other smaller motorway sections that will be linked to the national motorway network in the future. See here an animation of Hungarian motorway developments : .
Motorways usually have 2 traffic lanes and an emergency lane on each direction, divided by a green zone and metallic rail. The speed limit is 130 km/h.
Expressways usually have no dividing lane in the middle, but sometimes have a metallic rail. The number of lanes is one per direction, with sections of 1+2 lanes. The speed limit is 110 km/h. Motorways and expressways cannot be used by vehicles that are not able to reach 60 km/h. There is a toll on all motorways, except M0. Trucks and buses have a separate toll system.
Those who wish to travel on these roads have to buy a sticker. Controversially, there is no option to buy a one-day or one-time pass for passenger cars.
Main roads usually have one lane per direction, no dividing rail. The speed limit is 110 km/h.
County roads have less traffic than main roads, the speed limit is 90 km/h.

India

,
, India.
In India, 'Highway' refers to one of the many National Highways and State Highways that run up to a total length of over 300,000 km consisting mostly of two-lane paved roads, changing into higher lanes mostly around cities. National Highways are designated as NH followed by the number.
As of 2009, the major cities in India – Ahmedabad, Pune, Bangalore, Hyderabad, Mumbai, Chennai, Kolkata, and Delhi – are connected by the Golden Quadrilateral or North-South and East-West Corridor, that consists of 4 to 6 laned roads. Other major cities are connected to it by the National Highways.
An expressway refers to any access controlled road with grade-separated intersections and make up a very small portion of India's highway network, at about 1454.4 km in length. Expressways are separate from the highway network, except for the Delhi-Gurgaon Expressway, which is part of NH 8. Agra-Lucknow Expressway is the longest expressway more than 300 km in India after its inauguration on 21 November 2016 replacing Yamuna Expressway 165 km, cost ₹150 billion.

Indonesia

The Indonesian national route system exists solely on Java. Examples of roads include Jakarta's Inner and Outer ring roads, the Cipularang Toll Road in West Java connecting Jakarta and Bandung, and the Trans-Java toll road.

Ireland

The Republic of Ireland has the 6th densest motorway network in Europe. 'N' road or 'R' road. The maximum speed is 120 km/h on motorways.
The main Inter Urban route Motorways connecting Dublin by motorway to the cities of Cork, Limerick, Waterford and Galway, as well as other projects, has increased the total motorway network in the state to approximately 1,017 kilometres.

Iran

In Iran the term highway ~ commonly known as autobahn, is applied to roads that are constructed by particular standards. The conventional speed limit of 120 km/h is in place for most highways. There are two types of highway in Iran:
  1. Inner cities highways: They can be found in larger cities such as Tehran. The main purpose of them is to prevent congestion and pass traffics through cities.
  2. Between cities highway: They connect different parts of the country together.

    Iraq

Israel

Italy

In Italy the term highway can be applied to superstrada and autostrada. Italy was the first country in the world to build such roads, the first one being the "Autostrada dei Laghi", from Milan to Varese, built in 1921 and finished in 1924. This system of early motorways was extended in the early 1930s till the early 1970s. Nowadays the Autostrade is a comprehensive system of about 6.500 km of modern motorways where the maximum speed limit is 130 km/h.

Japan

The expressways, or kōsokudōro, of Japan are made of a huge network of freeway-standard toll roads. Once government-owned, they have been a turned over to private companies. Most expressways are four lanes with a central reservation, or median. The speed limits, with certain regulations and great flexibility, usually include a maximum speed of 100 km/h, and a minimum speed of 50 km/h.

Lithuania

Malaysia

The highest level of major roads in Malaysia, expressway , has full access control, grade separated junctions, and mostly tolled. The expressways link the major state capitals in Peninsular Malaysia and major cities in Klang Valley.
Highway is lower level with limited access control, some at-grade junctions or roundabouts, and generally with 2 lanes in each separated direction. These are generally untolled and funded by the federal government, hence the first one is called Federal Highway linking Klang and Kuala Lumpur.
The trunk roads linking major cities and towns in the country are called federal trunk roads, and are generally 2 lanes single carriageway roads, in places with a third climbing lane for slow lorries.

Mexico

Morocco

New Zealand

In New Zealand, both motorway and an expressway have at least two lanes of traffic in either direction separated by a median, with no access to adjacent properties. The distinction depends on the type of traffic allowed to use the route. Non-vehicular traffic and farm equipment are prohibited from motorways, while pedestrians, cyclists, tractors, and farm animals are legally entitled to use expressways such as the Waikato Expressway south of the Bombay Hills and the Tauranga expressway system, although this is rare. New Zealand's main routes are designated state highways as they are funded by the central government. State Highway 1 is the only route to run through both the North and South Islands, and runs from Cape Reinga to Wellington in the North Island, and from Picton to Bluff in the South Island. State Highways 2–5 are main routes in the North Island, State Highways 6–9 in the South Island, and state highways numbered from 10 onwards are generally found in numerical order from north to south. State highways usually incorporate different standards of roads, for example, State Highway 1 from Auckland to Hamilton incorporates the Northern and Southern Motorways in the Auckland area, the Waikato Expressway, and a rural road before passing through the streets of Hamilton. The term freeway is rarely used relating to New Zealand roads.

Netherlands

The Autosnelweg system is in constant development. Most of its parts are owned and funded by the government, but in recent times Public-private partnership come more and more into practice, such as in a part of the A59 between Oss and 's-Hertogenbosch. The Netherlands has the highest density highway network of Europe at 56.5 km per 1000 km², followed by Belgium. The 'Autosnelwegen', the main corridors, are designated with an A while secondary connecting roads have an N number. Sections of the A network are also part of the International E-road network in connecting with neighboring Belgium, Germany and England, the latter by ferry. The speed limit is 130 km/h, unless noted otherwise, and 120 km/h, 100 km/h or 80 km/h on various locations. This is done to reduce exhaust emissions and to limit noise to surrounding residential areas.

North Macedonia

Total length of the Macedonian motorways as of Spring 2019 is 317 km, with another 57 km being under construction. There are plans to extend the network with works planned to start in 2020. Major sections are A1, which connects the northern to the southern border, A2 connects Skopje, Tetovo and Gostivar. A3 connects Skopje to the eastern town of Stip.

Norway

Norway has a national highway system, numbered 2-899. Some main highways are also European highways and have an E before the number. The highways are often relatively narrow and curvy. Near the larger cities, especially around Oslo and Trondheim, there are motorways. Norway has also been engaged in recent decades in boring some extremely long highway tunnels through the mountain ranges, and some of these, now the world's longest, are so long that they have hollowed-out caverns in the midst of them for motorists to stop and take rests.

Pakistan

Pakistan has its own network of highways and motorways. Motorways extending from M1 to M10 will eventually connect whole length of the country from Peshawar to Karachi. The M2, the first motorway, was built in 1997 with the contract being awarded to the Korean firm Daewoo. It linked the federal capital Islamabad with Punjab's provincial capital Lahore. The network was then extended to Sargodha and then to Faisalabad with the M3. M1 highway to the Khyber Pakhtunkhwa's capital Peshawar had been completed in October 2007. M4, M5, M6, and M7 have been planned and also being built by local and foreign firms. This will connect Faisalababd, Multan, Dera Ghazi Khan, Rotadero to Karachi. N5 links Karachi to other cities.
Entry on all Pakistan highways is restricted to fast moving wheelers only. Slow-moving traffic and two wheelers are not allowed and construction and agricultural machinery is also restricted. Highway Police personnel use heavy motor bikes and fast moving Range Rovers for patrolling and are quite good at maintaining the traffic system. M9 and M10 are also functional now that connect Karachi to Hayderabad. The LSM which is 103 km is under construction and will be completed by 2010.
Expressways are similar to motorways with lesser access restrictions and are owned, maintained and operated either federally or provincially.
Pakistan's Motorways are patrolled by Pakistan's National Highways & Motorway Police, which is responsible for enforcement of traffic and safety laws, security and recovery on the Pakistan Motorway network. The NH&MP use SUVs, cars and heavy motorbikes for patrolling purposes and uses speed cameras for enforcing speed limits.

Philippines

Portugal

Poland

Polish public roads are grouped into categories related to administrative division. Poland has of public roads, of which are unpaved :
Polish motorways and expressways are part of national roads network.

Romania

Romania currently has five operational highways, summing up to 807 km; They are now being extended and additionally, another four motorways are planned to be built by 2020.
.
There are no tolls for using the motorways in Romania, except Cernavodă Bridge over the Danube on the A2. Nevertheless, every Romanian car that uses a motorway or a national road in Romania must pay a toll, specifically a vignette.
A few years ago the vignette was ported to an electronic format, thus eliminating the need of a physical display.

Russia

Russia has many highways, but only small number of them are currently motorways. Examples of Russian motorways are Moscow and Saint Petersburg Ring Roads. Highways and motorways are free in Russia and only two motorways, Western High Speed Diameter and Moscow-Saint Petersburg toll motorway, currently under construction, will be first Russian toll motorways. Russians themselves often translate the Russian name for highway into motorway in English, which is not a correct English name, it should be highway.

Saudi Arabia

Saudi Arabia has a total highway length of 73,000 km. Highways in Saudi Arabia vary from ten laned roads to small four laned roads. The city highways and other major highways are well maintained such as the roads in Riyadh. The roads are constructed so they resist the summer's extremely high heat and do not reflect the strong sun. The outer city highways such as the one linking from coast to coast are not as great as the inner-city Riyadh highway is fasts highways in KSA but the government is now working on rebuilding those roads.
Some of the important inter-city highways include:
The highways in Serbia are classified as IA state roads and common name for highway is auto-put which functions based on toll pay system and controlled access. Serbia currently has 876 km of total length of highways, while 1,154 km are planned. Because of its geographical position, it is very important for transit of capital, goods and services through Europe and Balkans, especially. As well it is one of most important countries on Balkans for Pan-european corridors.
The signs on Serbian highways are green colored and speed limit is 130 km/h. The history of Serbian highways starts with socialist Yugoslavia, when increased production influenced on enlargement of transit on public roads. The first highway to be built was brotherhood and unity highway that encompassed Slovenia, Croatia, Serbia and Macedonia. That highway was part of the pan-european corridor X and was built around 1970-ties.

Singapore

The expressways of Singapore are all dual carriageways with grade-separated access. They usually have three lanes in each direction, although there are two- or five-lane carriageways in some places. There are nine expressways, with the newest one, the Marina Coastal Expressway which is constructed under modern technology under the water.
Construction on the first expressway, the Pan Island Expressway, started in 1966. The other expressways were completed in stages, with the first phase of the Kallang-Paya Lebar Expressway being the most recently completed, in 2007. Today, there are 164 kilometres of expressways in Singapore.

Slovakia

The highways in Slovakia are divided into motorways and expressways.
The first modern highway in Slovakia should have been in the 30s planned motorway connecting Prague with northern parts of Slovakia; however the construction of the Slovak motorways was not started until 1970s.
As of December 2018, of motorways and of expressways are in service, with another being under various stages of construction.

Slovenia

The highways in Slovenia are the central state roads in Slovenia and are divided into motorways and expressways. Motorways are dual carriageways with a speed limit of 130 kilometres per hour. They have white-on-green road signs as in Italy, Croatia and other countries nearby. Expressways are secondary roads, also dual carriageways, but without an emergency lane. They have a speed limit of 110 kilometres per hour and have white-on-blue road signs.

South Africa

Colloquially, the terms "freeway", "highway", and "motorway" are used synonymously. The term "expressway" is not common in South Africa. A freeway, highway or motorway refers to a divided dual carriageway with limited access, and at least two lanes in either direction. A central island, usually either with drainage, foliage, or high-impact barriers, provides a visible separation between the carriageways in opposite directions. As in the United Kingdom, Ireland, Australia, and Japan, South Africans drive on the left-hand side of the road and nearly all steering wheels are on the right-hand side of vehicles.
Freeways are designated with one of three labels: N, R, and M. This has more to do with the location of a road and its function than anything else. In addition, "N" roads usually run the length of the country over long distances, "R" roads usually inter-connect cities and towns within a province, and "M" roads carry heavy traffic in metropolitan areas. Route markings also determine who paid for the road: "N" was paid for by national government, "R" by provincial government, and "M" by local government. In recent years, some "R" roads have been re-designated as "N" roads, so that control and funding comes from the South African National Roads Agency.

South Korea

Expressways in South Korea were originally numbered in order of construction. Since August 24, 2001, they have been numbered in a scheme somewhat similar to that of the Interstate Highway System in the United States:
Spain's national highway system dates back to the era of King Carlos III. The roads built at this time, radiating from Madrid, form the basis for the carreteras nacionales radiales, numbered clockwise from I to VI, which radiate from Madrid to major ports or border crossings. In the 1960s Spain started to construct autopistas and autovías, and in 2016 had 17,109 km of highways, the biggest network in Europe and the fourth in the world, only after the USA, India, and China.

Sri Lanka

is the first expressway in Sri Lanka. It travers from Kottawa to Matara and the construction of the section from Kottawa to Pinnaduwa was completed as a dual Expressway with 4-lane facility and declared open in November 2011. Galle Port access road has been built to connect Galle city to Pinnaduwa interchange. The design speed of this Expressway is 120 km/h. The operation speed of the Expressway is 100 km/h. The Southern Expressway will be extended up to Hambantota connecting Mattala Rajapaksa International Airport and the Magampura Mahinda Rajapaksa Port.
The second expressway to be declared open in Sri Lanka was the Colombo - Katunayake Expressway that was opened for public from October 2013, which also connects Sri Lanka's premier international airport Bandaranaike International Airport with capital Colombo.
Colombo Outer Circular Expressway, which is currently under construction, is designed to link the major expressways connected to Sri Lanka's commercial hub, Colombo, bypassing the traffic within the city limits.

Sweden

The first freeway in Sweden was built between the cities of Malmö and Lund in the Skåne County in southern Sweden. The Swedish roads are divided in three classes; Motorväg, which is a 4-8 lane motorway with the speed limit of 110–120 km/h. Riksväg, which is a state highway with 2-4 lanes. The Riksväg has a speed limit of 70–100 km/h. The last road is the Länsväg, which is a "county route" with 2 lanes and 70–90 km/h in speed limit. The authority which is responsible for the roads in Sweden is Trafikverket.

Switzerland

The term Autobahn / Autoroute / Autostrada is used for normal highways where there is a central physical structure separating two different directional carriageways. This is often translated into English as motorways.
In express routes where there is no central physical structure separating two different directional carriageways, but crossings are still motorway-like otherwise, and traffic lights are not present, the road is instead called an Autostrasse / Semi-autoroute / Semi-autostrada, usually translated into English as an expressway. Those often have a lower speed limit than motorways.

Taiwan

The construction of Taiwan's national highways began in 1971 and the design is heavily based on the American Interstate Highway System. The Northern section between Keelung City and Zhongli City was completed in 1974. The construction of the first freeway was completed in 1978. The freeway runs from the northern port city cf Keelung to the southern port city of Kaohsiung. There was an 8.6 km branch connecting the Taiwan Taoyuan International Airport.
Construction on the other freeways began in the late 1980s. The north section of the second north–south freeway between Xizhi City and Hsinchu City was completed in 1997. The No. 1A Branch was extended to link No. 3 Freeway at Yingge, and renamed as No. 2 Freeway. Three other short freeways were built to link the two north–south freeways in Taichung County, Tainan County, and Kaohsiung County, respectively. The entire No. 3 Freeway was completed in January, 2004.
To ease the congestion of No. 1 Freeway in the Taipei metropolitan area, a 20 km elevated bridge was built in 1997 on top of the original freeway between Xizhi City and Wugu, to serve as a bypass for traffic not exiting/entering the freeway within the city limits of Taipei.
The construction of a freeway connecting the Taipei metropolitan area and Yilan County began in 1991 and was completed in June 2006. It includes a 12.9 km tunnel, which is the fifth longest road tunnel in the world. An extension from Yilan County to Hualian County is planned. However, its construction is being delayed due to environmental concerns.

Thailand

The motorways in Thailand is an intercity toll controlled-access highways network that currently spans 145 kilometres. It is to be greatly extended to 4,154.7 kilometres according to the master plan. Thailand's motorway network is considered to be separate from Thailand's expressway network, which is the system of expressways, usually elevated, within Greater Bangkok. Thailand also has a provincial highway network.

Turkey

Turkey's main highway is E80 runs from Edirne to the capital Ankara.

United Kingdom

In the United Kingdom, the terms used for vehicular highways other than motorways include main road, trunk road, 'A' road / 'B' road, 'C' road, and unclassified road; they may additionally, where appropriate, be described as dual carriageways. However, in the law of England and Wales the term public highway includes all public rights of way regardless of the kind or amount of traffic they allow, including streets and public footpaths for pedestrians. The term also includes bridleways, which are for pedestrians, equestrians, and cyclists, as well as by-ways open to all traffic.
In England and Wales, the public is said to have a "right of way" over a highway. This means that, subject to statutory restrictions, the route must be kept clear to allow travel by anyone who wishes to it. At common law, it is unlawful to obstruct a highway or to interfere with its lawful use. However, many statutory provisions provide powers to do so.
Many public highways in the UK have a private owner. That is, someone can prove "title" to them, either by being the registered owner or by having conveyances showing exactly how the land has been bought and sold over a long period of time. Such ownership in no way affects the public highway rights, since the relevant "highway authority" is deemed to own the surface of the highway, despite someone else's ownership of the land it passes over or under.
Rights-of-way exist over all highways maintained at the public expense and also over some other ways which are not so maintained, on the principle of "once a highway, always a highway". In such cases, landowners must allow public use for "passing and repassing".
A right-of-way may be created by custom or under the relevant Sections of the Highways Act of 1980. A right-of-way may be extinguished or diverted in a number of ways, such as by an Act of Parliament, by a magistrates' stopping-up or diversion order, or by powers given to principal local authorities. For instance, under the Channel Tunnel Rail Link Act of 1996, authority was given for the builder of this railway link to stop up certain highways that are mentioned in Schedule 3 of the act.
The opposite of a highway is a private road or pathway over which no rights-of-way exist. Any use of such private ways is subject to the consent of the owner of the land.
Richard Mabey poses the origin of the word "highway" back to the Romans in his book "The Roadside Wildlife Book", 1974: "Daniel Defoe, writing in the 1720s, describes the Fosse Way as being raised eight or nine feet in many places. Between AD 40 and 80, the Romans laid something like 6,500 miles of highway.

United States

In the United States, "highway" is a general term for denoting a public way, including the entire area within the right-of-way, and includes many forms:
  1. a high-speed, limited-access road like expressways, two-lane expressway, freeways, and large toll highways.
  2. an important road that connects cities and large towns.
  3. any road or street, or a travel way of any kind, including pedestrian ways, trails, and navigable waterways, to which the public has a perpetual right of use.
Note that the phrase "right-of-way" is used differently in the United States than it is in the United Kingdom and certain other places. In the U.S. a highway or road "right-of-way" means the land on which the pavement rests, plus the shoulders beside the pavements, plus any median strip, plus any other adjacent piece of land that is designated for the purposes of the highway or road. In other words, the "right-of-way" is the strip of land for the highway or road, and a sign that says, "No Parking on Right-of-Way" means that drivers may not park on the pavement or on the land adjacent to it.
Many paved highways for vehicles are part of the official National Highway System of the U.S.. Paved highways in the United States Numbered Highway System can vary from two lanes wide, shoulderless, roads with no access control, to multi-lane high-speed controlled-access highway, such as the Interstate Highways. These roads are usually distinguished by being important, but not always the primary, routes that connect populated areas. Since their inception many decades ago, the construction of U.S. Highways, and their major improvements, have been paid for 50% with federal funds, especially from motor fuel taxes, and 50% with state funds from whatever tax resources that the state has. Thus, the system of U.S. Highways has always been an equal partnership between the federal government and the state governments. This was a plan that changed dramatically with the advent of the Interstate Highway System beginning in the 1950s, but do not forget that the system of U.S. Highways continued to be upgraded under the 50%-50% funding. Highways continue to be widened, old bridges continue to be replaced with newer and better ones, and so forth.
The term Highways in the U.S. even includes major paved roads that serve purposes similar to those of the U.S. Highways or Interstate Highways, but which are completely designed, paid for, and maintained by state or local governments. An example of this is M-6, which is an urban bypass of Grand Rapids, Michigan, that is a multi-lane, controlled-access highway entirely designed and paid for by Michigan. Much of the traffic uses it to bypass downtown Grand Rapids to make connections between Interstate 96, Interstate 196 and U.S. Highway 131.
When the Act of Congress that authorized the Interstate Highway System was passed and then signed by President Eisenhower, it was already clear that the Interstate Highways would be far more expensive, mile-for-mile, than the U.S. Highways had been. Because of their great cost, Congress decided to set the standard for federal funding for the Interstate System at 90%, leaving 10% for the states to pay for.
Another monetary difference came from the fact that the Interstate Highways were to be designed to be high-speed and safe expressways. This meant that they needed to have much wider open strips of land along their sides, because this created safety zones on each side of the highways so that vehicles that were in accidents or simply lost control would have somewhere to go, to slow down gradually, and not crash into trees, boulders, light poles, buildings, parked vehicles, fire hydrants, and other kinds of obstacles. Roadway interchanges for Interstate Highways were also to be very large. With so much land being taken away for the highways, the only way to justify it and to make it politically palatable was for the Federal and State governments to outright purchase all of the land. There could be no question of just having an easement for the highway and its right-of-way. All of the land within the right-of-way would be permanently owned by the governments, until such time that they decided to get rid of the highway and sell the land.
In some places, highway is a synonym for road or street, and in some cases, the word highway is simply used in cases of carelessness and laziness on the part of the speaker, who believes that street, road, and highway are all synonymous and uses them accordingly. On the other hand, in another example, the California Motor Vehicle Code § 360 states: "'Highway' is a way or place of whatever nature, publicly maintained and open to the use of the public for purposes of vehicular travel. Highway includes street." 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 town of Venice, California, are "highways" also entitled to be maintained with state highway funds.
The federal and state governments are trying to improve their National Highway System components by repaving highways, widening highways, replacing bridges, and reconstructing some interchanges. Many cloverleaf interchanges are being converted to parclo interchanges. Busy Diamond interchanges are also being converted to SPUIs or to parclos to reduce interchange congestion.
Arguably, the most famous United States highway is U.S. Route 66. It is immortalized in the song " Route 66"", and by the TV series Route 66. Other famous highways in songs include Highway 61, Carefree Highway in Arizona, Colorado Boulevard in Pasadena, California, the song "Ventura Highway", named for a highway in Southern California, and Blues Highway in Mississippi.

Yemen

Yemen has one of the oldest highway routes in the region. The first highway route was between Aden and Hadromout, with a two lane highway. Currently, Yemen has 71,300 kilometers of roads, of which only 6,200 kilometers are paved.

Zimbabwe

Zimbabwe has one of the better road networks in Africa that had been poorly maintained until recently. There has been an introduction of toll gates and the dualization of most of the major roads.
