Henry Hudson Bridge
The Henry Hudson Bridge is a steel arch toll bridge in New York City across the Spuyten Duyvil Creek. It connects Spuyten Duyvil in the Bronx with Inwood in Manhattan to the south, via the Henry Hudson Parkway (NY 9A). On the Manhattan side, the parkway goes into Inwood Hill Park. Commercial vehicles are not permitted on this bridge or on the parkway in general. The bridge is operated by MTA Bridges and Tunnels, an affiliate agency of the Metropolitan Transportation Authority. Design The bridge was designed by David B. Steinman, drawing upon his 1911 Ph.D. thesis in civil engineering at Columbia University. Named to commemorate the voyage of Henry Hudson on the '' Half Moon'', which anchored near the site in 1609, it was the longest plate girder arch and fixed arch bridge in the world when it opened in 1936. The bridge has two roadway levels carrying a total of seven traffic lanes and a pedestrian walkway and spans Spuyten Duyvil Creek just east of where the tidal strai ...

Inwood Hill Park
Inwood Hill Park is a public park in the Inwood neighborhood of Manhattan, New York City, operated by the New York City Department of Parks and Recreation. On a high schist ridge that rises above the Hudson River from Dyckman Street to the northern tip of the island, Inwood Hill Park's densely folded, glacially scoured topography contains the largest remaining old-growth forest on Manhattan Island, known as the Shorakapok Preserve after an historic Wecquaesgeek village. Unlike other Manhattan parks, Inwood Hill Park is largely natural and consists of mostly wooded, non-landscaped hills. History Site Inwood Hill Park has a human history that goes back to the Pre-Columbian era. Through the 17th century, Native Americans known as the Wecquaesgeek inhabited the area. There is evidence of a main encampment along the eastern edge of the park, known as the village of Shorakapok. The Wecquaesgeek relied on both the Hudson and Harlem Rivers as sources for food.

Parkway (New York)
The majority of parkways in the US state of New York are part of a statewide parkway system owned by several public and private agencies but mostly maintained by the New York State Department of Transportation (NYSDOT). A handful of other roads in the Hudson Valley and on Long Island are also known as parkways but are not part of the state system. The roads of the state parkway system were among the first limited-access roads to be constructed. These highways were not divided and allowed no driveway cuts, but did have intersections for some of the streets they crossed. A small section of the privately financed Long Island Motor Parkway was the first limited-access road to begin operation as a toll road and the first highway to use bridges and overpasses to eliminate intersections. The individual parkways vary widely in composition. Some, such as the Sprain Brook Parkway, are functionally equivalent to a freeway; others, like Seven Lakes Drive, are two-lane undivided surface ...

Spuyten Duyvil Bridge
The Spuyten Duyvil Bridge is a railroad swing bridge that spans the Spuyten Duyvil Creek between Manhattan and the Bronx, in New York City. The bridge is located at the northern tip of Manhattan where the Spuyten Duyvil Creek meets the Hudson River, approximately to the west of the Henry Hudson Bridge. The Spuyten Duyvil Bridge was built to carry two tracks but now carries only a single track on the eastern side of the span. It is part of the West Side Line, and is used by Amtrak trains traveling along the Empire Connection. The span is used by approximately 30 trains a day and is opened over 1,000 times per year, primarily during the summer months for Circle Line Sightseeing Cruises and recreational vessels. History A wooden railroad drawbridge across the Spuyten Duyvil was first constructed by the New York & Hudson River Railroad in 1849. The railroad continued southward along the West Side Line to St. John's Park Terminal in Lower Manhattan and carried both freight and ...

Hudson River
The Hudson River is a river that flows from north to south primarily through eastern New York. It originates in the Adirondack Mountains of Upstate New York and flows southward through the Hudson Valley to the New York Harbor between New York City and Jersey City, eventually draining into the Atlantic Ocean at Lower New York Bay. The river serves as a political boundary between the states of New Jersey and New York at its southern end. Farther north, it marks local boundaries between several New York counties. The lower half of the river is a tidal estuary, deeper than the body of water into which it flows, occupying the Hudson Fjord, an inlet which formed during the most recent period of North American glaciation, estimated at 26,000 to 13,300 years ago. Even as far north as the city of Troy, the flow of the river changes direction with the tides. The Hudson River runs through the Munsee, Lenape, Mohican, Mohawk, and Haudenosaunee homelands. Prior to European ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tidal Strait
A tidal strait is technically not a river but a strait connecting two oceans or seas. Tidal straits are narrow seaways through which tidal currents flow. Tidal currents are usually unidirectional but sometimes are bidirectional. They are frequently of tectonic origin. In them, currents develop because of elevation differences between the water basins at both ends. Tides sometimes allow sediments to collect in tidal straits. See also * Sediment trap (geology) * Tidal circularization Tidal circularization is an effect of the tidal forces between an orbiting body and the primary object that it orbits, whereby the eccentricity of the orbit is reduced over time so that the orbit becomes less and less elliptical. In figure 1 let ...

Half Moon (ship)
''Halve Maen'' (; en, Half Moon) was a Dutch East India Company '' vlieboot'' (similar to a carrack) that sailed into what is now New York Harbor in September 1609. She was commissioned by the VOC Chamber of Amsterdam in the Dutch Republic to covertly find a western passage to China. The ship was captained by Henry Hudson, an Englishman in the service of the Dutch Republic. In 1909, the Kingdom of the Netherlands presented the United States with a replica of ''Halve Maen'' to commemorate the 300th anniversary of Hudson's voyage; the replica was destroyed in a fire in 1934. Fifty years later, the New Netherland Museum commissioned a second replica. History ''Halve Maen'' sailed from Amsterdam to the Arctic, turning southwest to traverse the Atlantic Ocean to North America, then sailed from Newfoundland to the south in search of the Northwest Passage. In his 1625 book ''New World'', which contains invaluable extracts from Hudson's lost journal, Johannes de Laet, a director of ...

Henry Hudson
Henry Hudson ( 1565 – disappeared 23 June 1611) was an English sea explorer and navigator during the early 17th century, best known for his explorations of present-day Canada and parts of the northeastern United States. In 1607 and 1608, Hudson made two attempts on behalf of English merchants to find a rumoured Northeast Passage to Cathay via a route above the Arctic Circle. In 1609, he landed in North America on behalf of the Dutch East India Company and explored the region around the modern New York metropolitan area. Looking for a Northwest Passage to Asia on his ship ''Halve Maen'' ("Half Moon"), he sailed up the Hudson River, which was later named after him, and thereby laid the foundation for Dutch colonization of the region. On his final expedition, while still searching for the Northwest Passage, Hudson became the first European to see Hudson Strait and the immense Hudson Bay. In 1611, after wintering on the shore of James Bay, Hudson wanted to press on to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Civil Engineering
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to global Fortune 500 companies. History Civil engineering as a discipline Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances in t ...

Thesis Or Dissertation
A thesis ( : theses), or dissertation (abbreviated diss.), is a document submitted in support of candidature for an academic degree or professional qualification presenting the author's research and findings.International Standard ISO 7144: DocumentationPresentation of theses and similar documents International Organization for Standardization, Geneva, 1986. In some contexts, the word "thesis" or a cognate is used for part of a bachelor's or master's course, while "dissertation" is normally applied to a doctorate. This is the typical arrangement in American English. In other contexts, such as within most institutions of the United Kingdom and Republic of Ireland, the reverse is true. The term graduate thesis is sometimes used to refer to both master's theses and doctoral dissertations. The required complexity or quality of research of a thesis or dissertation can vary by country, university, or program, and the required minimum study period may thus vary significantly in dur ...

Doctor Of Philosophy
A Doctor of Philosophy (PhD, Ph.D., or DPhil; Latin: or ') is the most common Academic degree, degree at the highest academic level awarded following a course of study. PhDs are awarded for programs across the whole breadth of academic fields. Because it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a Thesis, dissertation, and defend their work before a panel of other experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields. Individuals who have earned a Doctor of Philosophy degree may, in many jurisdictions, use the title ''Doctor (title), Doctor'' (often abbreviated "Dr" or "Dr.") with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society.
