Partial Cloverleaf Interchange
A partial cloverleaf interchange or parclo is a modification of a cloverleaf interchange. The design has been well received, and has since become one of the most popular freeway-to-arterial interchange designs in North America. It has also been used occasionally in some European countries, such as Germany, Hungary, Italy, the Netherlands, and the United Kingdom. Comparison with other interchanges *A diamond interchange has four ramps. *A cloverleaf interchange has eight ramps, as does a stack interchange. They are fully grade separated, unlike a parclo, and have traffic flow without stops on all ramps and throughways. *A parclo generally has either four or six ramps but less commonly has five ramps. Naming In Ontario, the specific variation is identified by a letter/number suffix after the name. Ontario's naming conventions are used in this article. The letter ''A'' designates that two ramps meet the freeway ''ahead'' of the arterial road, while ''B'' designates that two ram ...

Annual Average Daily Traffic
Annual average daily traffic, abbreviated AADT, is a measure used primarily in transportation planning, transportation engineering and retail location selection. Traditionally, it is the total volume of vehicle traffic of a highway or road for a year divided by 365 days. AADT is a simple, but useful, measurement of how busy the road is. AADT is the standard measurement for vehicle traffic load on a section of road, and the basis for most decisions regarding transport planning, or to the environmental hazards of pollution related to road transport. Uses One of the most important uses of AADT is for determining funding for the maintenance and improvement of highways. In the United States the amount of federal funding a state will receive is related to the total traffic measured across its highway network.

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 ''throughway'' 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, 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, intersections or property access. They are free of any at-grade crossings with other roads, railways, or pedestrian paths, which are instead carried by overpasses and underpasses. Entrances and exits to the highway are provided at interchanges by slip roads (ramps), which allow for speed changes between the highway and arterials ...

Limited-access Highway
A limited-access road, known by various terms worldwide, including limited-access highway, dual-carriageway, expressway, limited access freeway, and partial controlled access highway, is a highway or arterial road for high-speed traffic which has many or most characteristics of a controlled-access highway (also known as a ''freeway'' or ''motorway''), including limited or no access to adjacent property, some degree of separation of opposing traffic flow, use of grade separated interchanges to some extent, prohibition of slow modes of transport, such as bicycles, (draught) horses, or self-propelled agricultural machines; and very few or no intersecting cross-streets or level crossings. The degree of isolation from local traffic allowed varies between countries and regions. The precise definition of these terms varies by jurisdiction.''

Highway Revolt
Highway revolts (also freeway revolts, expressway revolts, or road protests) are organized protests against the planning or construction of highways, freeways, expressways, and other civil engineering projects that favor vehicles. Many freeway revolts took place in developed countries during the 1960s and 1970s, in response to plans for the construction of new freeways, as advocated for by the highway lobby. A significant number of these highways were abandoned or significantly scaled back due to widespread public opposition, especially of those whose neighborhoods would be disrupted or displaced by the proposed freeways, and due to various other negative effects that freeways are considered to have. Freeway revolts have gained renewed interest in the 21st Century, with activists pushing to bury highways underground or remove freeways from cities to repair the damage to neighborhoods displaced by highway construction in the 20th Century.

Clinch River
The Clinch River is a river that flows southwest for more than through the Great Appalachian Valley in the U.S. states of Virginia and Tennessee, gathering various tributaries, including the Powell River, before joining the Tennessee River in Kingston, Tennessee. Course The Clinch River is dammed twice: by Norris Dam, the first dam built by the Tennessee Valley Authority (TVA); and by the Melton Hill Dam, the only TVA dam with a navigation lock that is not located on the main channel of the Tennessee River. An important tributary of the Clinch River is the Powell River. The Clinch and Powell River drainage basins are separated by Powell Mountain. Tributaries entering the Clinch River below Norris Dam but above Melton Hill Dam include Coal Creek, Hinds Creek, Bull Run Creek, and Beaver Creek. Poplar Creek enters the river below the Melton Hill Dam. History A peninsula located at the mouth of the Clinch River, called Southwest Point, was the site of an early frontier fort ...

Federal Highway Administration
The Federal Highway Administration (FHWA) is a division of the United States Department of Transportation that specializes in highway transportation. The agency's major activities are grouped into two programs, the Federal-aid Highway Program and the Federal Lands Highway Program. Its role had previously been performed by the Office of Road Inquiry, Office of Public Roads and the Bureau of Public Roads. History Background The organization has several predecessor organizations and complicated history. The Office of Road Inquiry (ORI) was founded in 1893. In 1905, that organization's name was changed to the Office of Public Roads (OPR) which became a division of the United States Department of Agriculture. The name was changed again to the Bureau of Public Roads in 1915 and to the Public Roads Administration (PRA) in 1939. It was then shifted to the Federal Works Agency which was abolished in 1949 when its name reverted to Bureau of Public Roads under the Department of Commerce ...
