Interstate
The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System, or the Eisenhower Interstate System, is a network of controlled-access highways that forms part of the National Highway System in the United States. The system extends throughout the contiguous United States and has routes in Hawaii, Alaska, and Puerto Rico. In the 20th century, the United States Congress began funding roadways through the Federal Aid Road Act of 1916, and started an effort to construct a national road grid with the passage of the Federal Aid Highway Act of 1921. In 1926, the United States Numbered Highway System was established, creating the first national road numbering system for cross-country travel. The roads were funded and maintained by U.S. states, and there were few national standards for road design. United States Numbered Highways ranged from two-lane country roads to multi-lane freeways. After Dwight D. Eisenhower becam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highway Revolts In The United States
Highway revolts have occurred in cities and regions across the United States. In many cities, there remain unused highways, abruptly terminating freeway alignments, and short stretches of freeway in the middle of nowhere, all of which are evidence of larger projects which were never completed. In some instances, freeway revolts have led to the eventual removal or relocation of freeways that had been built. In the post-World War II economic expansion, there was a major drive to build a freeway network in the United States, including (but not limited to) the Interstate Highway System. Design and construction began in earnest in the 1950s, with many cities and rural areas participating. However, many of the proposed freeway routes were drawn up without considering local interests; in many cases, the construction of the freeway system was considered a regional (or national) issue that trumped local concerns. Starting in 1956, in San Francisco, when many neighborhood activists b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Gaps In Interstate Highways
There are gaps in the Interstate Highway System where the roadway carrying an Interstate shield does not conform to the Interstate Highway standards, standards set by the Federal Highway Administration (FHWA), the body that sets the regulations for the Interstate Highway System. For the most part, the Interstate Highway System in the United States is a connected system, with most freeways completed; however, some Interstates still have gaps. These gaps can be due to unconnected segments of the same route or from failure of the road to fully conform to Interstate standards by including such characteristics as at-grade crossings, traffic lights, undivided or narrow freeways, or movable bridges (vertical lift bridge, lift bridges and bascule bridge, drawbridges). True gaps True gaps are where multiple disjoint sections of road have the same Interstate highway number and can reasonably be considered part of "one highway" in theory, based on the directness of connections via other hi ...

Controlled-access Highway
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway, and expressway. Other similar terms include ''wikt:throughway, throughway'' or ''thruway'' and ''parkway''. Some of these may be limited-access highways, although this term can also refer to a class of highways with somewhat less isolation from other traffic. In countries following the Vienna Convention on Road Signs and Signals, Vienna convention, the motorway qualification implies that walking and parking are forbidden. A fully controlled-access highway provides an unhindered flow of traffic, with no traffic signals, Intersection (road), intersections or frontage, property access. They are free of any at-grade intersection, at-grade crossings with other roads, railways, or pedestrian paths, which are instead carried by overpasses and underpasses. Entrances and exits to t ...

United States Numbered Highway System
The United States Numbered Highway System (often called U.S. Routes or U.S. Highways) is an integrated network of roads and highways numbered within a nationwide grid in the contiguous United States. As the designation and numbering of these highways were coordinated among the states, they are sometimes called Federal Highways, but the roadways were built and have always been maintained by state or local governments since their initial designation in 1926. The route numbers and locations are coordinated by the American Association of State Highway and Transportation Officials (AASHTO). The only federal involvement in AASHTO is a nonvoting seat for the United States Department of Transportation. Generally, most north-to-south highways are odd-numbered, with the lowest numbers in the east and the highest in the west, while east-to-west highways are typically even-numbered, with the lowest numbers in the north, and the highest in the south, though the grid guidelines are not r ...

List Of Future Interstate Highways
In the United States, future Interstate Highways include proposals to establish new mainline (one- and two-digit) routes to the Interstate Highway System. Included in this article are auxiliary Interstate Highways (designated by three-digit numbers) in varying stages of planning and construction, and the planned expansion of existing primary Interstate Highways. Congressionally designated future Interstates Several Congressional High Priority Corridors have been designated as future parts of the Interstate Highway System by the Intermodal Surface Transportation Efficiency Act and amendments. By law, they will become interstates when built to Interstate standards and connected to other interstates. Interstate 3 Interstate 3 is the proposed designation of an Interstate Highway Corridor under development in the Southeastern United States. It is planned to run from Savannah, Georgia, to Knoxville, Tennessee. Its number does not follow standard numbering conventions; under e ...

MUTCD M1-10a
The ''Manual on Uniform Traffic Control Devices for Streets and Highways'' (usually referred to as the ''Manual on Uniform Traffic Control Devices'', abbreviated MUTCD) is a document issued by the Federal Highway Administration (FHWA) of the United States Department of Transportation (USDOT) to specify the standards by which traffic signs, road surface markings, and signals are designed, installed, and used. Federal law requires compliance by all traffic control signs and surface markings on roads "open to public travel", including state, local, and privately owned roads (but not parking lots or gated communities). While some state agencies have developed their own sets of standards, including their own MUTCDs, these must substantially conform to the federal MUTCD. The MUTCD defines the content and placement of traffic signs, while design specifications are detailed in a companion volume, ''Standard Highway Signs and Markings''. This manual defines the specific dimensions, co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toll Road
A toll road, also known as a turnpike or tollway, is a public or private road for which a fee (or ''Toll (fee), toll'') is assessed for passage. It is a form of road pricing typically implemented to help recoup the costs of road construction and Road maintenance, maintenance. Toll roads have existed in some form since Classical antiquity, antiquity, with tolls levied on passing travelers on foot, wagon, or horseback; a practice that continued with the automobile, and many modern tollways charge fees for motor vehicles exclusively. The amount of the toll usually varies by vehicle type, weight, or number of axles, with freight trucks often charged higher rates than cars. Tolls are often collected at toll plazas, toll booths, toll houses, toll stations, toll bars, toll barriers, or toll gates. Some toll collection points are automatic, and the user deposits money in a machine which opens the gate once the correct toll has been paid. To cut costs and minimise time delay, many tolls ...

Highway Trust Fund
The Highway Trust Fund is a transportation fund in the United States which receives money from a federal fuel tax of 18.4 cents per gallon on gasoline and 24.4 cents per gallon of diesel fuel and related excise taxes. It currently has two accounts, the Highway Account funding road construction and other surface transportation projects, and a smaller Mass Transit Account supporting mass transit. Separate from the Highway Trust Fund is the Leaking Underground Storage Tank Trust Fund, which receives an additional 0.1 cents per gallon on gasoline and diesel, making the total amount of tax collected 18.5 cents per gallon on gasoline and 24.5 cents per gallon on diesel fuel. The Highway Trust Fund was established in 1956 to finance the United States Interstate Highway System and certain other roads. The Mass Transit Account was created in 1982. The federal tax on motor fuels yielded $28.2 billion in 2006. History Prior to the Federal Aid Highway Act of 1956 and the establishment ...

Road Signs In The United States
Road signs in the United States are, for the most part, standardized by federal regulations, most notably in the '' Manual on Uniform Traffic Control Devices'' (MUTCD) and its companion volume the ''Standard Highway Signs'' (SHS). Adoption and compliance The 11th edition of the MUTCD was released on December 19, 2023. The effective date, 30 days after publication, of the MUTCD was January 18, 2024. States have two years after the effective date to do one of the following options: adopt the revised MUTCD, adopt the revised MUTCD with a state supplement, or adopt a state-specific MUTCD. Eighteen states use the manual without alterations; 22 states, the District of Columbia, and Puerto Rico have adopted it in conjunction with a supplemental volume; and ten states have a state version in substantial conformance to the MUTCD. The MUTCD and SHS establish seven categories of signs for road and highway use, as follows: (The list does not cover all situations; the signage is from the ...

Traffic Light
Traffic lights, traffic signals, or stoplights – also known as robots in South Africa, Zambia, and Namibia – are signaling devices positioned at intersection (road), road intersections, pedestrian crossings, and other locations in order to control the flow of traffic. Traffic lights usually consist of three signals, transmitting meaningful information to road users through colours and symbols, including arrows and bicycles. The usual traffic light colours are red to stop traffic, Amber (color), amber for traffic change, and green to allow traffic to proceed. These are arranged vertically or horizontally in that order. Although this is internationally standardised, variations in traffic light sequences and laws exist on national and local scales. Traffic lights were first introduced in December 1868 on Parliament Square in London to reduce the need for police officers to control traffic. Since then, electricity and computerised control have advanced traffic light technolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
