Interstate 80 (Eastshore Freeway) in Berkeley, California: a typical American freeway (MUTCD definition)

A freeway — also known as a highway, superhighway, autoroute, autobahn, autopista, autovía, autostrada, dual carriageway, expressway, or motorway — is a type of road designed for safer high-speed operation of motor vehicles through the elimination of at-grade intersections. Interstate 80 (I-80 is the second-longest Interstate Highway in the United States (after I-90) The Eastshore Freeway is a segment of Interstates 80 and 580 along the northeast shoreline of San Francisco Bay in northern California. Berkeley is a city on the east shore of San Francisco Bay in Northern California, in the United States. * * * * * * * * * * * * * * * * * * * * * * Before adding any more images to this * * page please do carefully consider * * whether they would be mere decoration * * or actually improve * * * * * * * * * * * * * * * * * * * * * * Before adding any more images to this * * page please do carefully consider * * whether they would be mere decoration * * or actually improve An expressway is a Divided highway for high-speed traffic with at least partial Control of access.

Washington ( is a state in the Pacific Northwest region of the United States. Not all roads bearing the name of freeway are in fact freeways by definition; for example, the William L. Wilson Freeway (U.S. Route 340) by Harpers Ferry, West Virginia, is a two-lane undivided roadway featuring at-grade intersections. The William L Wilson Freeway is a portion of US Route 340 located in West Virginia between Harpers Ferry West Virginia and Charles Town West Virginia US Route 340 is a spur of US Route 40. It currently runs for 156 miles (251 km from Frederick Maryland at U Harpers Ferry redirects here For other uses see Harpers Ferry (disambiguation.

The crossing of freeways by other routes is typically achieved with grade separation either in the form of underpasses or overpasses. A tunnel is an underground passageway The definition of what constitutes a tunnel is not universally agreed upon An overpass (called a flyover in the UK and most Commonwealth countries is a Bridge, Road, Railway or In addition to sidewalks (footpaths) attached to roads that cross a freeway, specialized pedestrian bridges or tunnels may also be provided.

Access to freeways is typically provided only at grade-separated interchanges, though lower-standard right-in/right-out access can be used for direct connections to side roads. Toronto (təˈrɒntoʊ colloquially pronounced or) is the largest city in Canada and is the provincial capital of Ontario Ontario (ɒnˈtɛrioʊ is a province located in the central part of Canada, the largest by population and second largest after Quebec Local-express lanes or collector-express lanes are a set of two same-direction one-way multi-lane roadways usually on a Freeway.

An arterial road is a moderate or high-capacity Road which is immediately below a Highway Level of service. However, sometimes it is necessary to exit onto a surface road to transfer from one freeway to another. An example of this would be Interstate 70 in the town of Breezewood, Pennsylvania.

The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located In most Commonwealth nations, freeway-like roads are referred to as motorways. The English noun commonwealth dates from the fifteenth century. Motorway is a term for both a type of Road and a classification or designation

Speed limits are generally higher on freeways, and are occasionally nonexistent (as on much of Germany's Autobahn network). For a discussion of the maximum speed possible in the universe see Speed of light and Special relativity. The Autobahns are the nationally coordinated Motorway system in Germany. Because higher speeds reduce decision time, freeways are usually equipped with a larger number of guide signs than other roads, and the signs themselves are physically larger. Most countries post signage known as traffic signs or road signs, at the side of Roads to Guide signs are often mounted on overpasses or overhead gantries so that drivers can see where each lane goes. A gantry is a Traffic sign assembly in which signs are mounted on an overhead support Exit numbers are commonly derived from the exit's distance in miles or kilometers from the start of the freeway. In some areas, there are public rest areas or service areas on freeways, as well as emergency phones on the shoulder at regular intervals.

In the United States, mileposts start at the southern or westernmost point on the freeway (either its terminus or the state line). California, Ohio, and Nevada uses a postmile system where markers indicate mileage through the state's individual counties, however Nevada and Ohio also use the standard milepost system concurrently with their respective postmile systems on freeways only.

These wide freeways may use separate collector and express lanes to separate through traffic from local traffic, or special high-occupancy vehicle lanes, either as a special restriction on the innermost lane or a separate roadway, to encourage carpooling. Local-express lanes or collector-express lanes are a set of two same-direction one-way multi-lane roadways usually on a Freeway. In Transportation engineering and Transportation planning, a high-occupancy vehicle lane (or HOV lane) is a lane reserved for Vehicles with Carpooling (also known as car-sharing, ride-sharing, lift-sharing) is the shared use of a car by the driver and one or more passengers usually These HOV lanes, or roadways open to all traffic, can be reversible lanes, providing more capacity in the direction of heavy traffic, and reversing direction before traffic switches.

In some parts of the world, notably Texas, frontage roads form an integral part of the freeway system. A frontage road (also access road, feeder, service drive, service road, outer road, and especially surface road) is A frontage road (also access road, feeder, service drive, service road, outer road, and especially surface road) is These parallel surface roads typically run the entire length of the freeway and provide a transition between high-speed "through" traffic and local traffic. Frequent slip ramps provide access from the freeway to the frontage road, which in turn provides direct access to local roads and businesses.

Access restrictions

A bicyclist using a freeway legally

To reduce the probability that high-speed freeway traffic will have to slow down for slower same-direction traffic, access to freeways is usually limited to drivers of motor vehicles which are powerful enough to maintain a certain minimum speed. The concept of a Freeway (a public way intended primarily for high speed travel over long distances has resulted in a set of highways with engineering features such as long sight A motor Vehicle is a Machine which incorporates a motor (sometimes known as an Engine) and which is used for Transportation Some East Asian countries partially restrict the use of motorcycles or ban them completely from freeways (or expressways in countries where that term is used) (see restrictions on motorcycle use on freeways).

Legal definitions

United States

Santa Clara County Route G4 (Montague Expressway), an American expressway under the MUTCD definition

In the United States, a "freeway" is defined by the federal government’s Manual on Uniform Traffic Control Devices as a divided highway with full control of access. County Route G4, more commonly referred to as San Tomas Expressway and Montague Expressway is a busy 14 The Manual on Uniform Traffic Control Devices (MUTCD is a document issued by the Federal Highway Administration (FHWA of the United States Department of Transportation ^[9] This means two things. Adjoining property owners do not have a legal right of access, meaning that they cannot connect their lands to the highway by constructing driveways, although frontage roads provide access to properties adjacent to a freeway in many places. A frontage road (also access road, feeder, service drive, service road, outer road, and especially surface road) is ^[10] When an existing road is converted into a freeway, all existing driveways must be removed and access to adjacent private lands must be blocked with fences or walls. Traffic on the highway is "free-flowing". All cross-traffic (and left-turning traffic) has been relegated to overpasses or underpasses, so that there are no traffic conflicts on the main line of the highway which must be regulated by a traffic light, stop signs, or other traffic control devices. Achieving such free flow requires the construction of many bridges, tunnels, and ramp systems. The advantage of grade-separated interchanges is that freeway drivers can almost always maintain their speed at junctions since they do not need to yield to crossing traffic.

In contrast, an expressway is defined as a divided highway with partial control of access. An expressway is a Divided highway for high-speed traffic with at least partial Control of access. ^[11] Expressways may have driveways and at-grade intersections, though these are usually less numerous than on ordinary arterial roads.

This distinction was apparently first developed in 1949 by the Special Committee on Nomenclature of what is now the American Association of State Highway and Transportation Officials. AASHTO, the American Association of State Highway and Transportation Officials, is a standards setting body which publishes specifications test protocols and ^[12] In turn, the definitions were incorporated into AASHTO's official standards book, the Manual on Uniform Traffic Control Devices, which would become the national standards book of the U.S. Department of Transportation under a 1966 federal statute. The United States Department of Transportation ( DOT) is a federal Cabinet department of the United States government concerned with Transportation The same distinction has also been codified into the statutory law of seven states: California,^[13] Mississippi,^[14] Missouri,^[15] Nebraska,^[16] North Dakota,^[17] Ohio,^[18] and Wisconsin. California ( is a US state on the West Coast of the United States, along the Pacific Ocean. Mississippi ( is a state located in the Deep South of the United States Missouri ( or) is a state in the Midwestern region of the United States bordered by Iowa, Illinois, Kentucky, Tennessee Nebraska ( is a state located on the Great Plains of the Midwestern United States and North Dakota ( is a state located in the Midwestern and Western regions of the United States of America. Ohio ( is a Midwestern state of the United States. As part of the Great Lakes region, Ohio has long been a cultural and geographical crossroads Wisconsin ( or wɪˈskɑnsɨn (French Ouisconsin) is one of the fifty United States of America, located in the north central part of the United States ^[19] However, each state codified the federal distinction slightly differently. California expressways do not necessarily have to be divided, though they must have at least partial access control. For both terms to apply, in Wisconsin, a divided highway must be at least four lanes wide; and in Missouri, both terms apply only to divided highways at least 10 miles (16 km) long that are not part of the Interstate Highway System. In North Dakota and Mississippi, an expressway may have "full or partial" access control and "generally" has grade separations at intersections; a freeway is then defined as an expressway with full access control. Ohio's statute is similar, but instead of the vague word generally, it imposes a requirement that 50% of an expressway's intersections must be grade-separated for the term to apply. ^[20]

The term expressway is also used^[2] for what the federal government calls "freeways"; see the expressway article for further information. An expressway is a Divided highway for high-speed traffic with at least partial Control of access. Where the terms are distinguished, all freeways are expressways, while not all expressways are freeways.

Freeways have been constructed both between urban centers and within them, leading to the sprawling suburban development found near most modern cities.

Freeways reduced travel times and accident rates, though the higher speeds have increased the severity and death rates of the collisions that do occur. A collision is an isolated event in which two or more bodies (colliding bodies exert relatively strong forces on each other for a relatively short time

Freeways have been heavily criticized by environmentalists, urbanists, and preservationists for the noise,^[21] pollution, and economic shifts they bring. Additionally, they have also been criticized by the driving public for the inefficiency with which they handle peak hour traffic. ^[22][23][24]

Often, rural freeways open up vast areas to economic development, generally raising property values. In contrast to this, above ground freeways in urban areas are often a source of lowered property values, contributing to urban decay. Urban decay is a process by which a City, or a part of a city falls into a state of disrepair Even with overpasses and underpasses, above ground freeways divide neighborhoods — especially impoverished ones where residents are less likely to own a car, or to have the political and economic influence to resist construction efforts. ^[25] Beginning in the early 1970s, the U. S. Congress identified freeways and other urban highways as responsible for most of the noise exposure of the U. S. population. ^[26] Subsequently, computer models were developed to analyze freeway noise and aid in their siting and design to minimize noise exposure. ^[27]

Some freeways have even been demolished and reclaimed as boulevards, notably in Portland (Harbor Drive), New York City (West Side Highway), Boston (Central Artery), San Francisco (Embarcadero Freeway) and Milwaukee (Park East Freeway). Boulevard ( French, from Bolwerk &ndash bolwark meaning bastion has several generally accepted meanings Portland is a city located in the Northwestern United States, near the Confluence of the Willamette and Columbia rivers Harbor Drive is the name of a street in Portland Oregon, which was formerly a Freeway that carried U The City of New York The West Side Highway (officially the Joe DiMaggio Highway, formerly the Miller Highway or West Side Elevated Highway) is a mostly-surface section of The Central Artery, officially the John F Fitzgerald Expressway, is a section of Freeway in downtown Boston Massachusetts, designated The City and County of San Francisco is the fourth most populous city State Route 480 was a proposed State highway in San Francisco California, United States, consisting of the elevated double-decker Embarcadero Freeway The Park Freeway was a Freeway planned and partially constructed in Milwaukee Wisconsin, United States.

An alternative to surface or above ground freeway construction has been the construction of underground urban freeways using tunnelling technologies. This has been extremely successful in the Australian cities of Sydney (which has five such freeways) and Melbourne (which has one such freeway). Sydney (ˈsɪdniː is the most populous city in Australia, with a Metropolitan area population of approximately 4 Melbourne ( is the second most populous city in Australia, with a Metropolitan area population of approximately 3 This has had the benefit of removing traffic from surface roads and has led to urban renewal due to a significant decrease in surface road traffic congestion, noise and pollution. Public transport has been improved in these areas through the provisioning of dedicated bus lanes where previously traffic congestion prevented such lane allocations from being made.

Other Australian cities face similar problems (lack of available land, cost of home acquisition, aesthetic problems, and community opposition). Brisbane, which also has to contend with physical boundaries (the river) and heavy population increases, has embraced underground tunnel freeways. There are currently three under active development, one of which (the North-South Bypass Tunnel) is currently under construction. The M7 Clem Jones Tunnel (CLEM7, known in development as the North-South Bypass Tunnel (NSBT, is a $3 All of the planned tunnels include provisions for public transport, whether underground or in reclaimed space on the surface. ^[28]

Freeway opponents have found that freeway expansion is often self-defeating: expansion simply generates more traffic. That is, even if traffic congestion is initially shifted from local streets to a new or widened freeway, people will begin to run errands and commute to more remote locations. Over time, the freeway and its environs become congested again as both the average number and distance of trips increases. This idea is known as induced demand. Induced demand is the phenomenon that after supply increases more of a good is consumed ^[29][30]

Interstate H-1 eastbound into Honolulu, USA.

Urban planning experts such as Drusilla Van Hengel, Joseph DiMento, and Sherry Ryan, argue that although properly designed and maintained freeways may be convenient and safe, at least in comparison to uncontrolled roads, they may not expand recreation, employment and education opportunities equally for different ethnic groups, or for people located in certain neighborhoods of a given city. ^[31] Still, they may open new markets to some small businesses. ^[32]

At present, freeway expansion has largely stalled in the United States, due to a multitude of factors that converged in the 1970s: higher due process requirements prior to taking of private property, increasing land values, increasing costs for construction materials, local opposition to new freeways in urban cores, the passage of the National Environmental Policy Act (which imposed the requirement that each new federally-funded project must have an environmental impact statement or report), and falling gas tax revenues as a result of the nature of the flat-cent tax (it is not automatically adjusted for inflation), the tax revolt movement,^[33] and growing popular support for high-speed mass transit in lieu of new freeways.

The Taconic State Parkway (often called the Taconic or the TSP) is a part of the New York State highway system The Sprain Brook Parkway is a long north-south Parkway in Westchester County New York. The Saw Mill River Parkway is a 289 mile north-south Parkway running diagonally through Westchester County New York. Designers elsewhere also researched similar ideas, especially in Germany, where the Autobahn would become the first national freeway system.

The Autostrada A9 or Autostrada dei Laghi (“Autostrada of the Lakes” is a motorway in northern Italy.

Meanwhile, in Great Britain, the related concept of the motorway was first proposed by Sidney Webb in a 1910 book, The King's Highway, but was not formally embraced by the government until the passage of the Special Roads Act 1949.

Joseph Hilaire Pierre René Belloc (27 July 1870 &ndash 16 July 1953 was a French -born Writer who became a Naturalised British subject Even if the wealth of the community increases, the thing would be impossible, because it would mean the destruction of such a proportion of buildings as would dislocate all social life. ^[36]

While Connecticut's Merritt Parkway was the first fully controlled-access highway in America when it opened on June 29, 1938, it does not qualify as the country's first freeway, since low bridge heights, tight curve radii, and short interchange ramps fell well below freeway standards. Connecticut ( is a state located in the New England region of the northeastern United States of America. The Merritt Parkway is a limited-access Parkway in Fairfield County Connecticut.

Today, many freeways in the United States belong to the extensive Interstate highway system (most of which was completed between 1960 and 1990). The Dwight D Eisenhower National System of Interstate and Defense Highways, commonly called the Interstate Highway System (or simply the Interstate System) Starting in the 1970s freeways began to consider environmental factors, particularly noise and air quality in their location and design. Nearly all Interstate highways are freeways. The earlier United States highway system and the highway systems of U.S. states also have many sections that are built to controlled-access standards (though these systems are mostly composed of uncontrolled roads). The system of United States Numbered Highways (often called U A US state is any one of the fifty subnational entities of the United States of America that share Sovereignty with the federal government Only a handful of sections of the Interstate system are not freeways, such as I-81 as it crosses the American span of the 2-lane Thousand Islands Bridge and a segment of Interstate 93 through Franconia Notch, New Hampshire that is a 2-lane road with partial access control.

Major progress has been made in making existing U. S. freeways and expressways more efficient. Innovations include the addition of high-occupancy vehicle lanes (HOV lanes) to discourage driving solo, and building new roads with train tracks down the median (or overhead). In Transportation engineering and Transportation planning, a high-occupancy vehicle lane (or HOV lane) is a lane reserved for Vehicles with A train is a connected series of vehicles that move along a track ( Permanent way) to transport freight or passengers from one place to another On divided roads including Expressways Motorways or Autobahns the central reservation (British English, median (North American California's Caltrans has been very innovative in squeezing HOVs into limited right-of-way (by elevating them), and in building special HOV-only ramps so that HOVs can switch freeways or exit the freeway without having to merge across regular traffic. The California Department of Transportation ( Caltrans) is a Government department in the U Many states have added truck-only ramps or lanes on heavily congested routes, so that cars need not weave around slow-moving big rigs.

Intelligent transportation systems are also increasingly used, with cameras to monitor and direct traffic, so that police, fire, ambulance, tow, or other assistance vehicles can be dispatched as soon as there is a problem, and to warn drivers via variable message signs, radio, television, and the Web to avoid problem areas. The term intelligent transportation system (ITS refers to efforts to add Information and communications technology to Transport Infrastructure A camera is a device used to capture images either as still Photographs or as sequences of moving images ( Movies or Videos.

Pragmatism generally considered to have originated in the late nineteenth century with Charles Peirce, who first stated the Pragmatic maxim.

Public-private partnerships in the United States

Until the late 1990s, funding of construction and maintenance of the Interstate Highway System was by the national gasoline tax. Originally, revenues generated by the national gasoline tax were intended solely for the maintenance and expansion of the country's highway system. During the Clinton Administration, federal legislation was passed allowing the use of gasoline tax revenues to fund other government programs and projects not related to highways or transportation. Since this reduced the amount of money available for the intended purpose of maintaining America's road network, many projects were either delayed, canceled, or scaled back.

Additionally, the original Highway Act of 1956 prohibited states from collecting tolls on Interstate-funded freeways. As more miles of freeways were completed, the cost of maintaining the infrastructure increased dramatically. A major issue that has slowed new freeway construction in America has been the application of highway funds to maintaining and repairing existing infrastructure. Most of the freeways in America are near or have exceeded their designed life span, which necessitates replacing of bridges and overpasses and reconstruction of the driving surfaces on many freeways nationwide.

To address the issue of lack of funding for new freeways and maintenance of existing roads, legislation enacted in 1998 gives states greater flexibility in funding major highway projects. Specifically the legislation, known as TEA-21 in official documents, authorizes states to add tolls to Interstate-funded freeways. Additionally, it gave states the latitude to enter into public-private partnership P3 arrangements to facilitate expansion and maintenance of the freeway network. Texas, Florida, Virginia, and California quickly took advantage of the TEA-21 legislation and began on massive projects to expand their respective states' freeway networks, complementing existing Interstate freeways with privately funded and operated tollways.
