Penn Street Bridge
The Penn Street Bridge, also known as the Penn Street Viaduct, is a historic bridge crossing the Schuylkill River into Reading, Pennsylvania, the largest city in Berks County and fourth-largest city in the state. The bridge is considered to be the primary gateway to downtown Reading, leading directly onto Penn Street, the main thoroughfare of the city. The opposite end of the bridge leads into the borough of West Reading and connects with an interchange onto the West Shore Bypass section of U.S. Route 422. As a result of the bridge's prominent location, it has an average daily traffic volume of nearly 34,000. Constructed in 1913, the bridge is one of the oldest examples in the region of an open-spandrel concrete arch bridge, and it retains good historic integrity including original ornate concrete railings; it was determined eligible for listing in the National Register of Historic Places in 2007 and reevaluated in 2019. History Before the bridge (before 1816) Prior to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Horse And Buggy
] A horse and buggy (in American English) or horse and carriage (in British English and American English) refers to a light, simple, two-person carriage of the late 18th, 19th and early 20th centuries, drawn usually by one or sometimes by two horses. Also called a roadster or a trap, it was made with two wheels in England and the United States (also made with four wheels). It had a folding or falling top. History A Concorde buggy, first made in Concord, New Hampshire, had a body with low sides and side-spring suspension. A buggy having two seats was called a double buggy. A buggy called a stanhope typically had a high seat and closed back. The bodies of buggies were sometimes suspended on a pair of longitudinal elastic wooden bars called ''sidebars''. A buggy whip had a small, usually tasseled tip called a ''snapper''. In countries such as the United States, the United Kingdom, and Canada, it was a primary mode of short-distance personal transportation, especially between 1 ...

Baluster
A baluster is an upright support, often a vertical moulded shaft, square, or lathe-turned form found in stairways, parapets, and other architectural features. In furniture construction it is known as a spindle. Common materials used in its construction are wood, stone, and less frequently metal and ceramic. A group of balusters supporting a handrail, coping, or ornamental detail are known as a balustrade. The term baluster shaft is used to describe forms such as a candlestick, upright furniture support, and the stem of a brass chandelier. The term banister (also bannister) refers to a baluster or to the system of balusters and handrail of a stairway. It may be used to include its supporting structures, such as a supporting newel post. Etymology According to the ''Oxford English Dictionary'', "baluster" is derived through the french: balustre, from it, balaustro, from ''balaustra'', "pomegranate flower" rom a resemblance to the swelling form of the half-open flower (''ill ...

Boring (earth)
Boring is drilling a hole, tunnel, or well in the Earth. It is used for various applications in geology, agriculture, hydrology, civil engineering, and mineral exploration. Today, most Earth drilling serves one of the following purposes: * return samples of the soil and/or rock through which the drill passes * access rocks from which material can be extracted * access rocks which can then be measured * provide access to rock for purposes of providing engineering support Unlike drilling in other materials where the aim is to create a hole for some purpose, often the case of drilling or coring is to get an understanding of the ground/lithology. This may be done for prospecting to identify and quantify an ore body for mining, or to determining the type of foundations needed for a building or raised structure, or for underground structures, including tunnels and deep basements where an understanding of the ground is vital to determining how to excavate and the support philosophy. ...

Bond (finance)
In finance, a bond is a type of security under which the issuer ( debtor) owes the holder ( creditor) a debt, and is obliged – depending on the terms – to repay the principal (i.e. amount borrowed) of the bond at the maturity date as well as interest (called the coupon) over a specified amount of time. The interest is usually payable at fixed intervals: semiannual, annual, and less often at other periods. Thus, a bond is a form of loan or IOU. Bonds provide the borrower with external funds to finance long-term investments or, in the case of government bonds, to finance current expenditure. Bonds and stocks are both securities, but the major difference between the two is that (capital) stockholders have an equity stake in a company (i.e. they are owners), whereas bondholders have a creditor stake in a company (i.e. they are lenders). As creditors, bondholders have priority over stockholders. This means they will be repaid in advance of stockholders, but will rank behind ...

Macadamizing
Macadam is a type of road construction, pioneered by Scottish engineer John Loudon McAdam around 1820, in which crushed stone is placed in shallow, convex layers and compacted thoroughly. A binding layer of stone dust (crushed stone from the original material) may form; it may also, after rolling, be covered with a cement or bituminous binder to keep dust and stones together. The method simplified what had been considered state-of-the-art at that point. Predecessors Pierre-Marie-Jérôme Trésaguet Pierre-Marie-Jérôme Trésaguet is sometimes considered the first person to bring post-Roman science to road building. A Frenchman from an engineering family, he worked paving roads in Paris from 1757 to 1764. As chief engineer of road construction of Limoges, he had opportunity to develop a better and cheaper method of road construction. In 1775, Tresaguet became engineer-general and presented his answer for road improvement in France, which soon became standard practice there ...

Philadelphia And Reading Railway Company
The Reading Company ( ) was a Philadelphia-headquartered railroad that provided passenger and commercial rail transport in eastern Pennsylvania and neighboring states that operated from 1924 until its 1976 acquisition by Conrail. Commonly called the Reading Railroad, and logotyped as Reading Lines, the Reading Company was a railroad holding company for the majority of its existence and was a single railroad during its later years. It operated service as Reading Railway System and was a successor to the Philadelphia and Reading Railway Company, founded in 1833. Until the decline in anthracite loadings in the Coal Region after World War II, it was one of the most prosperous corporations in the United States. Competition with the modern trucking industry that used the interstate highway system for short-distance transportation of goods, also known as short hauls, compounded the company's problems, forcing it into bankruptcy in 1971. Its railroad operations were merged into Conrail i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Girder
A girder () is a support beam used in construction. It is the main horizontal support of a structure which supports smaller beams. Girders often have an I-beam cross section composed of two load-bearing ''flanges'' separated by a stabilizing ''web'', but may also have a box shape, Z shape, or other forms. Girders are commonly used to build bridges. A girt is a vertically aligned girder placed to resist shear loads. Small steel girders are rolled into shape. Larger girders (1 m/3 feet deep or more) are made as plate girders, welded or bolted together from separate pieces of steel plate. The Warren type girder replaces the solid web with an open latticework truss between the flanges. This arrangement combines strength with economy of materials, minimizing weight and thereby reducing loads and expense. Patented in 1848 by its designers James Warren and Willoughby Theobald Monzani, its structure consists of longitudinal members joined only by angled cross-members, f ...

Trolley Car
A tram (called a streetcar or trolley in North America) is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way. The tramlines or networks operated as public transport are called tramways or simply trams/streetcars. Many recently built tramways use the contemporary term light rail. The vehicles are called streetcars or trolleys (not to be confused with trolleybus) in North America and trams or tramcars elsewhere. The first two terms are often used interchangeably in the United States, with ''trolley'' being the preferred term in the eastern US and ''streetcar'' in the western US. ''Streetcar'' or ''tramway'' are preferred in Canada. In parts of the United States, internally powered buses made to resemble a streetcar are often referred to as "trolleys". To avoid further confusion with trolley buses, the American Public Transportation Association (APTA) refers to them as "trolley-replica buses". In the United ...
