Highway

Any public or private road, as well as any other public way on land, is referred to as a highway. It refers to major highways, as well as minor public roads and tracks. It is used as a synonym for controlled-access highway or a translation for autobahn, auto route, and other terms in various parts of the United States.

The term's use dates back to the 12th century, according to Merriam Webster. "High" is used in the sense of "major" according to Etymonline.

Major roads, such as controlled-access motorways or arterial roads, are frequently referred to as state highways in English in North America and Australia (Canada: provincial high) These classifications correspond to the level of government that is responsible for maintaining the road (state, province, or county).

"Highway" is largely a legal term in British English. In most cases, everyday usage refers to roadways, whereas legal use refers to any route or path with a public right of access, such as footpaths.

Highway system, highway code, highway patrol, and highwayman are all concepts that have been developed from the term.ways). In the United States and Ontario, other roadways are called "county highways."

Highway Overview

The governments that create and maintain major roadways frequently name and number them. At approximately 14,500 kilometers (9,000 miles), Australia's Highway 1 is the world's longest national highway, running virtually the entire length of the continent. China has the greatest roadway network in the world, followed by the United States of America. Some highways cross many nations, such as the Pan-American Highway or European routes. Ferry services are available on certain key highway routes, such as US Route 10, which crosses Lake Michigan.

People on foot or on horses used to travel the highways. Later, when road construction improved, they were able to accommodate carriages, bicycles, and eventually automobiles. Many countries began spending extensively in increasingly advanced highway systems in the 1920s and 1930s to boost commerce and national defense.

Major contemporary highways connecting cities in densely populated developed and developing countries typically have elements that improve the road's capacity, efficiency, and safety to varying degrees. A reduction in the number of user access points, the use of dual carriageways with two or more lanes on each carriageway, and grade-separated connections with other roadways and modes of transportation are examples of such features. These elements are common on highways developed as expressways (freeways).

History of Highway

Mediterranean and Middle Eastern ancient roadways

Animal routes were the first highways, which humans eventually adopted. The earliest evidence of such routes dates from circa 6000 BC and was discovered near some springs in Jericho. Stone-paved streets in modern-day Iraq and surviving timber roadways in a marsh in Glastonbury, England, are among the earliest evidences of built roads, going back to roughly 4000 BC. The availability of metal tools throughout the Bronze Age made stone paving more practical; at the same time, the use of wheeled vehicles, which were firmly established by 2000 BC, increased demand for paved roads.

The longest highway in the world

The United States is home to the bulk of the world's ten longest highways, including the world's longest, the Pan American Highway, which stretches for 48,000 kilometers. The 10 longest highways in the world, according to overall length, are listed on roadtraffic-technology.com.

The world is home to a variety of spectacular highways known for their breath-taking magnificence and the huge distances they cover. Some of them pass through a variety of landscapes including mountains, plains, and forests, which are beautiful to look at yet risky to cross, while others pass through hustling and busy towns. We've compiled a list of the world's top ten highways in terms of length.

1. Pan American Highway

Pan American Highway


The Pan American Highway, which spans the entirety of the United States' interstate highway system, is the world's longest highway, stretching for about 48,000 kilometers.

It connects more than 20 nations in the Americas, with the exception of the Darién Gap, which is a 100-kilometer gap halfway between Panama and Colombia.

The highway project began in 1923 and extends from Buenos Aires, Argentina, to Edmonton, Alberta, Canada. Mexico finished the first section of the roadway in 1950.

The sections of the highway that go through Mexico were built and funded entirely by Mexico, whereas the sections that run through the smaller Central American countries were built and funded entirely by the United States.

2. Highway 1, Australia

Australia's Highway 1 is the world's second-longest highway and the country's longest national highway. It has a total length of 14,500 kilometers and is made up of interconnecting roadways.

In 1955, Highway 1 was designated as a national highway. It has both single-lane and multilane roadways. Except for Brisbane and Darwin, which are not directly connected, the route passes through every state in Australia. The roadway runs parallel to the Australian National Highway for the bulk of its length.

Highway 1's original path, established in 1955, was rerouted in 1959, 1974, and 1998. The roadway transports about a million people every day.

3. Trans-Siberian Highway

The Trans-Siberian Highway, with 11,000 kilometers in length, is the world's third longest highway. It extends throughout Russia from St. Petersburg to Vladivostok. The AH6 refers to the segment of the road that crosses the Asian Highway Network.

The highway, which runs parallel to European route E30 and traverses across Kazakhstan, is made up of seven federal highways. The Russian route M58, often known as the Amur Highway, stretches 2,100 kilometers from Chita to Khabarovsk and is a federal highway in Russia.

4. Trans-Canada Highway

The Trans-Canada Roadway is the world's fourth longest highway and the second longest national highway, with a total length of about 7,821 kilometers.

Building on the roadway began in 1950 and was completed in 1962, however paving and other construction work continued until 1971. The total amount invested was roughly $1 billion.

From Victoria, British Columbia, to St. John's City, Newfoundland and Labrador, the route runs east-west. It runs through all ten Canadian provinces and connects all of the country's major cities.

5. Golden Quadrilateral Highway Network India

The Golden Quadrilateral is the world's fifth longest roadway, connecting the four major Indian cities of Delhi, Mumbai, Chennai, and Kolkata by a network of highways. The 5,846-kilometer highway's planning work was finished in 1999, construction began in 2001, and the route was completed in January 2012.

The National Highways Authority of India (NHAI), which is part of the Ministry of Road, Transport and Highways, built the roadway for Rs600 billion ($9.2 billion) and maintains it.

Along the whole journey, the roadway has four to six lanes. It was built in four portions, each of which was allocated to a different contractor.

6. China National Highway 010

China National Highway 010

China National Highway 010, often known as the Tongan Expressway, is the world's sixth-longest highway at 5,700 kilometer's. It's also the country's longest national highway.

From Tongjiang City in eastern Heilongjiang Province to Sanya in Hainan Province, the route runs. It is China's seventh east-west highway and one of the country's five north-south highways.

Heilongjiang, Jilin, Liaoning, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, and Guangdong are among the provinces it travels through. The Quanzhou Strait at Hai'an in Guangdong, where cars are transported across by trains to Haikou in Hainan, before ending in Sanya, creates a missing link.

7. US Route 20

US Route 20 is the world's seventh longest roadway and the longest route in the United States, stretching 5,415 kilometers from Boston, Massachusetts, to Newport, Oregon.

In 1926, the roadway was opened, and in 1940, it was extended. It runs through nine US states and is cut in half by Yellowstone National Park in Wyoming.

Prior to its enlargement in 1940, US Route 20 came to an end at Yellowstone National Park. The highway's western half intersects with US 101, while its eastern section runs parallel to the Massachusetts Turnpike, a 138-mile (222-kilometer) length of Interstate 90.

8. US Route 6

From Bishop, California, to Provincetown, Massachusetts, US Route 6 (also known as the Grand Army of the Republic Highway) runs. It is the eighth-longest highway in the world, as well as the second-longest and longest continuous roadway in the United States, with a total length of 5,158 kilometers.

Until 1964, the highway went from Bishop, California, to Long Beach, California, and was considered a transcontinental route.

In the 1920s and 1930s, it was also known as Roosevelt Highway and subsequently the Midland Trail Roadway before being officially designated by the American Association of State Highway Officials (AASHO), which developed the US numbering system for identifying the nation's major Interstate highways.

9. Interstate 90 (I-90), US

From Boston, Massachusetts, to Seattle, Washington, Interstate 90 (I-90) runs. The highway is 4,860.2 kilometers long, making it the world's seventh longest roadway and the United States' longest Interstate Highway.

For the most part, the route travels parallel to US Route 20 and passes through 13 states. The construction of the I-90 began in the 1950s. The entire roadway was completed in 1985, and for the most part, it used existing roads.

The Lacey V. Murrow Memorial Bridge and the Homer M. Hadley Memorial Bridge, which span Lake Washington from Seattle to Mercer Island, are two of the longest floating bridges in the world.

10. Interstate 80 (I-80), US

Interstate 80 (I-80), also known as Christopher Columbus Roadway in some areas along its course, is a 4,666-kilometer-long highway that is the world's tenth longest and the United States' second-longest interstate highway.

The roadway, known as the Bergen-Passaic Expressway, begins at an intersection with US Route 101 in San Francisco, California, and concludes in New Jersey, where it spans for 68 kilometers. It runs through 11 states in the United States.

Nebraska has the longest continuous section of I-80, spanning 116 kilometers from Exit 318 in the Grand Island area and mile marker 390 near Lincoln, Nebraska. It is also the longest stretch of the United States' complete Interstate Highway System.

Conclusion

The developed & developing countries are building networks of modern highways day to day. The development of road infrastructure brings major changes to transportation. These numbers may change in the future.
