Joralemon Street Tunnel
The Joralemon Street Tunnel, originally the Brooklyn–Battery Tunnel, is a pair of tubes carrying the IRT Lexington Avenue Line () of the New York City Subway under the East River between Bowling Green Park in Manhattan and Brooklyn Heights in Brooklyn, New York City. The Joralemon Street Tunnel was an extension of the Interborough Rapid Transit Company (IRT)'s first subway line from the Bowling Green station in Manhattan to the IRT Eastern Parkway Line in Brooklyn. The tubes were constructed using the shield method and are each long and wide. The interiors are lined with cast-iron "rings" formed with concrete. The tubes descend below the mean high water level of the East River, with a maximum gradient of 3.1 percent. During the tunnel's construction, a house at 58 Joralemon Street in Brooklyn was converted into a ventilation building and emergency exit. The Joralemon Street Tunnel was the first underwater subway tunnel connecting Manhattan and Brooklyn. It was built ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Postcard
A postcard or post card is a piece of thick paper or thin cardboard, typically rectangular, intended for writing and mailing without an envelope. Non-rectangular shapes may also be used but are rare. There are novelty exceptions, such as wooden postcards, copper postcards sold in the Copper Country of the U.S. state of Michigan, and coconut "postcards" from tropical islands. In some places, one can send a postcard for a lower fee than a letter. Stamp collectors distinguish between postcards (which require a postage stamp) and postal cards (which have the postage pre-printed on them). While a postcard is usually printed and sold by a private company, individual or organization, a postal card is issued by the relevant postal authority (often with pre-printed postage). Production of postcards blossomed in the late 19th and early 20th centuries. As an easy and quick way for individuals to communicate, they became extremely popular. The study and collecting of postcards is terme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mean High Water
A chart datum is the water level surface serving as origin of depths displayed on a nautical chart. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. Common chart datums are ''lowest astronomical tide'' (LAT)Australian Bureau of MeteorologNational Tide Centre Glossary(retrieved 30 April 2013) and ''mean lower low water'' (MLLW). In non-tidal areas, e.g. the Baltic Sea, mean sea level (MSL) is used. A chart datum is a type of vertical datum and must not be confused with the horizontal datum for the chart. Definitions The following tidal phases are commonly used in the definition of chart datums. Lowest astronomical tide ''Lowest astronomical tide'' (LAT) is defined as the lowest tide level which can be predicted to occur under average meteorological conditions and under any combination of astronomical conditions. Many national charting agencies, including the United Kingdom Hydrographic Office and the Australian Hydr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keystone (architecture)
A keystone (or capstone) is the wedge-shaped stone at the apex of a masonry arch or typically round-shaped one at the apex of a vault. In both cases it is the final piece placed during construction and locks all the stones into position, allowing the arch or vault to bear weight. In arches and vaults (such as quasi-domes) keystones are often enlarged beyond the structural requirements and decorated. A variant in domes and crowning vaults is a lantern. Keystones, as a hallmark of strength or good architecture, or their suggested form are sometimes placed in the centre of the flat top of doors, recesses and windows for decorative effect, so as to form an upward projection of a lintel. Although a masonry arch or vault cannot be self-supporting until the keystone is placed, the keystone experiences the least stress of any of the voussoirs, due to its position at the apex. Old keystones can decay due to vibration, a condition known as bald arch. Architecture In a rib-vaulted c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brooklyn–Battery Tunnel
The Brooklyn–Battery Tunnel, officially the Hugh L. Carey Tunnel and commonly referred to as the Battery Tunnel or Battery Park Tunnel, is a tolled tunnel in New York City that connects Red Hook in Brooklyn with the Battery in Manhattan. The tunnel consists of twin tubes that each carry two traffic lanes under the mouth of the East River. Although it passes just offshore of Governors Island, the tunnel does not provide vehicular access to the island. With a length of , it is the longest continuous underwater vehicular tunnel in North America. Plans for the Brooklyn–Battery Tunnel date back to the 1920s. Official plans to build the tunnel were submitted in 1930 but were initially not carried out. The New York City Tunnel Authority, created in 1936, was tasked with constructing the tunnel. After unsuccessful attempts to secure federal funds, New York City Parks Commissioner Robert Moses proposed a Brooklyn–Battery Bridge. However, the public opposed the bridge plan, an ...

South Ferry (Manhattan)
South Ferry is at the southern tip of Manhattan in New York City and is the embarkation point for ferries to Staten Island (Staten Island Ferry, through the Staten Island Ferry Whitehall Terminal) and Governors Island. Battery Park, abutting South Ferry on the west, has docking areas for ferries to Liberty Island and Ellis Island. Its name is derived from the more southerly route of service of the historical South Ferry Company in comparison to the Fulton Ferry. History The name "South Ferry" derives from a more southerly route of service than previous ferry lines between what were then the separate cities of New York and Brooklyn, rather than from being at the southern tip of Manhattan. The "Old Ferry" (later renamed the Fulton Ferry), crossed between Manhattan and Brooklyn from streets that in each city would eventually be renamed "Fulton Street". The "New Ferry" (also called the Catherine Ferry) crossed on a more northerly route than the Old Ferry, between Catherine ...
