Maryland Route 715
Maryland Route 715 (MD 715) is a state highway in Harford County in the U.S. state of Maryland. Known as Short Lane, the state highway runs from U.S. Route 40 (US 40) in Aberdeen east to an entrance to Aberdeen Proving Ground. MD 715 was constructed during World War II as a military access project. Between 2010 and 2013, the state highway was reconstructed to better handle the increased traffic brought by the Base Realignment and Closure (BRAC) process. Route description MD 715 begins at a modified trumpet interchange with US 40 (Philadelphia Boulevard). The state highway heads east from US 40 as a six-lane divided highway that intersects Old Philadelphia Road and the entrance to an industrial park. MD 715 crosses over Amtrak's Northeast Corridor railroad line and MARC's Penn Line and passes north of the Visitor Center of Aberdeen Proving Ground as it reaches its eastern terminus at an entrance to Aberdeen Proving Ground.

State Highway
A state highway, state road, or state route (and the equivalent provincial highway, provincial road, or provincial route) is usually a road that is either ''numbered'' or ''maintained'' by a sub-national state or province. A road numbered by a state or province falls below numbered national highways (Canada being a notable exception to this rule) in the hierarchy (route numbers are used to aid navigation, and may or may not indicate ownership or maintenance). Roads maintained by a state or province include both nationally numbered highways and un-numbered state highways. Depending on the state, "state highway" may be used for one meaning and "state road" or "state route" for the other. In some countries such as New Zealand, the word "state" is used in its sense of a sovereign state or country. By this meaning a state highway is a road maintained and numbered by the national government rather than local authorities. Countries Australia Australia's State Route system covers u ...

Maryland
Maryland ( ) is a state in the Mid-Atlantic region of the United States. It shares borders with Virginia, West Virginia, and the District of Columbia to its south and west; Pennsylvania to its north; and Delaware and the Atlantic Ocean to its east. Baltimore is the largest city in the state, and the capital is Annapolis. Among its occasional nicknames are '' Old Line State'', the ''Free State'', and the '' Chesapeake Bay State''. It is named after Henrietta Maria, the French-born queen of England, Scotland, and Ireland, who was known then in England as Mary. Before its coastline was explored by Europeans in the 16th century, Maryland was inhabited by several groups of Native Americans – mostly by Algonquian peoples and, to a lesser degree, Iroquoian and Siouan. As one of the original Thirteen Colonies of England, Maryland was founded by George Calvert, 1st Baron Baltimore, a Catholic convert"George Calvert and Cecilius Calvert, Barons Baltimore" William Hand Browne, ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Base Realignment And Closure
Base Realignment and Closure (BRAC) is a process by a United States federal government commission to increase United States Department of Defense efficiency by coordinating the realignment and closure of military installations following the end of the Cold War. More than 350 installations have been closed in five BRAC rounds: 1988, 1991, 1993, 1995, and 2005. These five BRAC rounds constitute a combined savings of $12 billion annually. Background The Federal Property and Administrative Services Act of 1949, passed after the 1947 reorganization of the National Military Establishment, reduced the number of US military bases, forts, posts, and stations. The subsequent 1950s buildup for the Cold War (e.g., during the Korean War) resulted in large numbers of new installations, such as the of Permanent System radar stations and Semi Automatic Ground Environment (SAGE) control centers. By 1959, plans for even larger numbers of Cold War installations were canceled (e.g., DoD's June 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trumpet 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] |
Divided Highway
A dual carriageway ( BE) or divided highway ( AE) is a class of highway with carriageways for traffic travelling in opposite directions separated by a central reservation (BrE) or median (AmE). Roads with two or more carriageways which are designed to higher standards with controlled access are generally classed as motorways, freeways, etc., rather than dual carriageways. A road without a central reservation is a single carriageway regardless of the number of lanes. Dual carriageways have improved road traffic safety over single carriageways and typically have higher speed limits as a result. In some places, express lanes and local/collector lanes are used within a local-express-lane system to provide more capacity and to smooth traffic flows for longer-distance travel. History A very early (perhaps the first) example of a dual carriageway was the ''Via Portuensis'', built in the first century by the Roman emperor Claudius between Rome and its port Ostia at the mouth of t ...

The Northeast Corridor (NEC) is an electrified railroad line in the Northeast megalopolis of the United States. Owned primarily by Amtrak, it runs from Boston through Providence, New Haven, Stamford, New York City, Philadelphia, Wilmington, and Baltimore to Washington, D.C. The NEC closely parallels Interstate 95 for most of its length, and is the busiest passenger rail line in the United States both by ridership and by service frequency as of 2013. The NEC carries more than 2,200 trains daily. The corridor is used by many Amtrak trains, including the high-speed Acela, intercity trains and several long-distance trains. Most of the corridor also has frequent commuter rail service, operated by the MBTA, Shore Line East, Hartford Line, Metro-North Railroad, Long Island Rail Road, New Jersey Transit, SEPTA and MARC.
