Interstate 440 In Tennessee
Interstate 440 (I-440) is an east–west auxiliary Interstate Highway that runs through Nashville, Tennessee. It serves as a southern bypass around downtown Nashville, and is located on average about from the center of the city. I-440 is also known locally as the Four-Forty Parkway, and is designated as the Debra K. Johnson Memorial Parkway. At a length of , I-440 runs between I-40 and I-24, and connects to I-65 and multiple U.S. Routes. Combined, I-440 and Briley Parkway, a controlled-access segment of State Route 155 (SR 155), form a noncontiguous inner beltway around downtown Nashville. Originally proposed in the 1950s, I-440 was the subject of much controversy related to its location and design, which resulted in multiple design changes and delayed the highway's completion for many years. As a result, it was the last segment of Interstate Highway planned for Tennessee in the Interstate Highway Act of 1956 to be constructed. After its completion in 198 ...

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 ...

Directional T Interchange
In the field of road transport, an interchange (American English) or a grade-separated junction (British English) is a road junction that uses grade separations to allow for the movement of traffic between two or more roadways or highways, using a system of interconnecting roadways to permit traffic on at least one of the routes to pass through the junction without interruption from crossing traffic streams. It differs from a standard intersection, where roads cross at grade. Interchanges are almost always used when at least one road is a controlled-access highway (freeway or motorway) or a limited-access divided highway (expressway), though they are sometimes used at junctions between surface streets. Terminology ''Note:'' The descriptions of interchanges apply to countries where vehicles drive on the right side of the road. For left-side driving, the layout of junctions is mirrored. Both North American (NA) and British (UK) terminology is included. ; Freeway junction, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interstate Highway System
The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway 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. The U.S. federal government first funded roadways through the Federal Aid Road Act of 1916, and began 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 still state-funded and maintained, however, and there was little in the way of national standards for road design. U.S. Highways could be anything from a two-lane country road to a major multi-lane freeway. After Dwight D. Eisenhower became president in 1953, his administration ...

Concurrency (road)
A concurrency in a road network is an instance of one physical roadway bearing two or more different route numbers. When two roadways share the same right-of-way, it is sometimes called a common section or commons. Other terminology for a concurrency includes overlap, coincidence, duplex (two concurrent routes), triplex (three concurrent routes), multiplex (any number of concurrent routes), dual routing or triple routing. Concurrent numbering can become very common in jurisdictions that allow it. Where multiple routes must pass between a single mountain crossing or over a bridge, or through a major city, it is often economically and practically advantageous for them all to be accommodated on a single physical roadway. In some jurisdictions, however, concurrent numbering is avoided by posting only one route number on highway signs; these routes disappear at the start of the concurrency and reappear when it ends. However, any route that becomes unsigned in the middle of the concurren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Berry Hill, Tennessee
Berry Hill is a city in Davidson County, Tennessee. According to the 2010 census, the city had a population of 537. The current mayor is Greg Mabey. History Much of the area of Berry Hill was originally owned by William Wells Berry (1813–1876) and his descendants. Residents of the area voted on whether to incorporate as a city on February 28, 1950. The vote was 138 to 135 favoring incorporation. Berry Hill became the first community in Davidson County to incorporate since Belle Meade incorporated in 1938. The population of Berry Hill at the time of incorporation numbered around 1,200.

Overpass
An overpass (called an overbridge or flyover in the United Kingdom and some other Commonwealth countries) is a bridge, road, railway or similar structure that crosses over another road or railway. An ''overpass'' and ''underpass'' together form a grade separation. Stack interchanges are made up of several overpasses. History The world's first railroad flyover was constructed in 1843 by the London and Croydon Railway at Norwood Junction railway station to carry its atmospheric railway vehicles over the Brighton Main Line. Highway and road In North American usage, a ''flyover'' is a high-level overpass, built above main overpass lanes, or a bridge built over what had been an at-grade intersection. Traffic engineers usually refer to the latter as a ''grade separation''. A flyover may also be an extra ramp added to an existing interchange, either replacing an existing cloverleaf loop (or being built in place of one) with a higher, faster ramp that eventually bears left, but may b ...

Stack Interchange
A directional interchange, colloquially known as a stack interchange, is a type of grade-separated junction between two controlled-access highways that allows for free-flowing movement to and from all directions of traffic. These interchanges eliminate the problems of weaving, have the highest vehicle capacity, and vehicles travel shorter distances when compared to different types of interchanges. The first directional interchange built in the world was the Four Level Interchange which opened to Los Angeles traffic in 1949. Definition A directional interchange is a grade separated junction between two roads where all turns that require crossing over or under the opposite road's lanes of travel in order to complete the turn utilize ramps that make a direct or semi-direct connection. The difference between direct and semi-direct connections is how much the motorist deviates from the intended direction of travel while on the ramp; direct ramps are shorter and can handle higher t ...

Spaghetti Junction
Spaghetti junction is a nickname sometimes given to a complex or massively intertwined road traffic interchange that is said to resemble a plate of spaghetti. Such interchanges may incorporate a variety of interchange design elements in order to maximize connectivity. Etymology The term was originally used to refer to the Gravelly Hill Interchange on the M6 motorway in Birmingham, United Kingdom. In an article published in the ''Birmingham Evening Mail'' on 1 June 1965 the journalist Roy Smith described plans for the junction as "like a cross between a plate of spaghetti and an unsuccessful attempt at a Staffordshire knot", with the headline above the article on the newspaper's front page, written by sub-editor Alan Eaglesfield, reading "Spaghetti Junction". Since then many complex interchanges around the world have acquired the nickname. Throughout North America, this type of interchange is widely referred to as a spaghetti junction, mixing bowl, knot, or maze, often inclu ...
