Interstate 440 (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 by the Federal-Aid Highway Act of 1956 to be constructed. After its completion in 1 ...

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 With the coming of the bicycle in the 1890s, interest grew regarding the improvement of streets and roads in America. The traditional method of putting the burden on maintaining roads on local landowners was increasingly inadequate. In 1893, the federal Office of Road Inquiry (ORI) was founded; in 1905, it was renamed the Office of Public Roads (OPR) and made a division of the United States Department of Agriculture. Demands grew for local and state government to take charge. With the coming of the automobile, urgent efforts were made to upgrade and moderniz ...

Annual Average Daily Traffic
Annual average daily traffic (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 some decisions regarding transport planning, or 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. Each year on June 15, every state's department of transportation (DOT) submits a Highway Performance Monitoring System (HPMS) report. The HPMS report contains various information regarding t ...

Concurrency (road)
In a road network, a concurrency is an instance of one physical roadway bearing two or more different route numbers. The practice is often economically and practically advantageous when multiple routes must pass between a single mountain crossing or over a bridge, or through a major city, and can be accommodated by a single right-of-way. Each route number is typically posted on highways signs where concurrencies are allowed, while some jurisdictions simplify signage by posting one priority route number on highway signs. In the latter circumstance, other route numbers disappear when the concurrency begins and reappear when it ends. In most cases, each route in a concurrency is recognized by maps and atlases. Terminology 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 con ...

Overpass
An overpass, called an overbridge or flyover (for a road only) in the United Kingdom and some other Commonwealth countries, is a bridge, road, railway or similar structure that is 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 eventua ...

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 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 traveling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Centennial Park (Nashville)
Centennial Park is a large urban area, urban park located approximately two miles (three km) west of downtown Nashville, Tennessee, United States, across West End Avenue (U.S. Highway 70S) from the campus of Vanderbilt University. The 21st-century headquarters campus of the Hospital Corporation of America was developed adjacent to the park. Cultivated as farmland by some of the earliest families in Nashville, the territory became controlled by the state and used as a park after the American Civil War. In the last decade, it was used as a racetrack. It was redeveloped as the site of the Tennessee Centennial and International Exposition in 1897. Afterward most of the temporary exhibit structures were removed, but the replica of the Parthenon remained. Centennial Park was opened in 1903. Due to the popularity of the Parthenon, it was rebuilt in steel and concrete between 1925 and 1931. History The park was originally farmland that had belonged to John Cockrill and his wife, Anne Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 or seven 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Main Line (railway)
The main line, or mainline in American English, of a railway is a track that is used for through trains or is the principal artery of the system from which branch lines, yards, sidings, and spurs are connected. It generally refers to a route between towns, as opposed to a route providing suburban or metro services. It may also be called a trunk line, for example the Grand Trunk Railway The Grand Trunk Railway (; ) was a Rail transport, railway system that operated in the Provinces and territories of Canada, Canadian provinces of Quebec and Ontario and in the List of states and territories of the United States, American sta ... in Canada, or the Trunk Line in Norway. For capacity reasons, main lines in many countries have at least a double track and often contain multiple parallel tracks. Main line tracks are typically operated at higher speeds than branch lines and are generally built and maintained to a higher standard than yards and branch lines. Main lines may als ...
