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.

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

Front Royal, Virginia
Front Royal is the only incorporated town in Warren County, Virginia, United States. The population was 15,011 at the 2020 census. It is the county seat of Warren County. History The entire Shenandoah Valley including the area to become Front Royal was annexed and claimed for hunting by the Iroquois Confederation during the later Beaver Wars, by 1672. Some bands of the Shawnee settled in the area as client groups to the Iroquois and alternately to the Cherokee after 1721. The Iroquois formally sold their entire claim east of the Alleghenies to the Virginia Colony at the Treaty of Lancaster in 1744. Front Royal, originally settled in 1754 under the name LeHewtown, had been known to European explorers as early as the 1670s, and the nearby settlement of Chester's Ferry was in existence by 1736. The town also had a well-known nickname by the 1790s, "Helltown," due to the many livestock wranglers and boatmen on the Shenandoah coming through the area, who came into town looki ...

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 ...

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] |
Foggy Bottom
Foggy Bottom is one of the oldest late 18th- and 19th-century neighborhoods in Washington, D.C., located west of the White House and downtown Washington, in the Northwest quadrant. It is bounded roughly by 17th Street NW to the east, Rock Creek Parkway to the west, Constitution Avenue NW to the south, and Pennsylvania Avenue NW to the north. Foggy Bottom is thought to have received its name due to an atmospheric quirk of its low lying, marshy riverside location, which made it susceptible to concentrations of fog, and later, industrial smoke. The United States Department of State gained the metonym "Foggy Bottom" when it moved its headquarters to the nearby Harry S Truman Building, originally planned and constructed to be the new United States Department of War headquarters building, from the State, War, and Navy Building (now known as the Eisenhower Executive Office Building) near the White House in 1947.Alex Carmine.
