Northeast Freeway (Washington, D.C.)
The Northeast Freeway was a planned freeway in Prince George's County, Maryland that would have run from the North Central Freeway in the District of Columbia northeast to the College Park Interchange on the Capital Beltway (I-495). The route would have carried Interstate 95 from the Capital Beltway into the District of Columbia. The entire route was canceled in 1977 after the government of the District of Columbia canceled the North Central Freeway, cutting off the southern end of the Northeast Freeway from the D.C. freeway network. The cancellation of the route led to the truncation of Interstate 95 at the College Park Interchange and its subsequent rerouting onto the eastern half of the Capital Beltway. The completed portion of I-95 that ran from downtown Washington to the Springfield Interchange in Virginia is now designated as I-395. The stub end of I-95 south of the College Park Interchange in Maryland was converted into a Park & Ride lot in 1986, and a new flyover ramp was ...

Roads In Washington, D
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", which in ...

Cut-and-cover
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. Tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Green Line runs from to . It was the last line in the original Metrorail plan to be constructed, and is one of three north–south lines through the city of Washington. The Green Line shares tracks with the Yellow line from to . Planning Planning for Metro began with the Mass Transportation Survey in 1955, which attempted to forecast both freeway and mass transit systems sufficient to meet the needs of the region projected for 1980. In 1959, the study's final report included two rapid transit lines which anticipated subways in downtown Washington. Because the plan called for extensive freeway construction within the District of Columbia, alarmed residents lobbied for legislation which both created a new transportation agency and blocked freeway construction. The agency, the National Capital T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fort Drive Parkway
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they acted ...
