Pinkerton's Landing Bridge
The Pinkerton's Landing Bridge (officially known as the Pittsburgh & Lake Erie Railroad Bridge at Munhall) is a truss bridge that carries CSX Transportation's Pittsburgh Subdivision across the Monongahela River between Munhall, Pennsylvania and Rankin, Pennsylvania, United States. The structure's nickname references the 1892 Homestead strike. It is also known as the Pemickey Bridge, for the Pittsburgh, McKeesport and Youghiogheny Railroad (P. McK. & Y., pronounced "Pemickey") which used to run over the bridge.

Munhall, Pennsylvania
Munhall is a borough in Allegheny County, Pennsylvania, United States, on the west bank of the Monongahela River, south of the confluence of the Monongahela and the Allegheny rivers where the Ohio River begins. It abuts the borough of Homestead. A large part of the Homestead Works of the Carnegie Steel Company existed in Munhall. Steel products were the only items made in Munhall in 1910 when 5,185 people lived here. In 1940, 13,900 people lived in Munhall. The population was 11,406 at the 2010 census. Munhall, along with the boroughs of Homestead and West Homestead, is served by the Steel Valley School District. History A post office called Munhall was established in 1887. The borough was formed on June 24, 1901, out of a part of Mifflin Township, and named for John Munhall, the original owner of the town site.

Steel Bridges In The United States
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Truss Bridges In The United States
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as ''nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary for t ...

Bridges In Allegheny County, Pennsylvania
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use.

Pittsburgh And Lake Erie Railroad
The Pittsburgh and Lake Erie Railroad (P&LE) , also known as the "Little Giant", was formed on May 11, 1875. Company headquarters were located in Pittsburgh, Pennsylvania. The line connected Pittsburgh in the east with Youngstown, Ohio in the Haselton neighborhood in the west and Connellsville, Pennsylvania to the east. It did not reach Lake Erie (at Ashtabula, Ohio) until the formation of Conrail in 1976. The P&LE was known as the "Little Giant" since the tonnage that it moved was out of proportion to its route mileage. While it operated around one tenth of one percent of the nation's railroad miles, it hauled around one percent of its tonnage. This was largely because the P&LE served the steel mills of the greater Pittsburgh area, which consumed and shipped vast amounts of materials. It was a specialized railroad deriving much of its revenue from coal, coke, iron ore, limestone, and steel. The eventual closure of the steel mills led to the end of the P&LE as an independent ...

CSX Transportation Bridges
CSX Transportation , known colloquially as simply CSX, is a Railroad classes, Class I freight railroad operating in the Eastern United States and the Canadian provinces of Ontario and Quebec. The railroad operates approximately 21,000 route miles () of track. The company operates as the leading subsidiary of CSX Corporation, a Fortune 500 company headquartered in Jacksonville, Florida. CSX Corporation (the parent of CSX Transportation) was formed in 1980 from the merger of Chessie System and Seaboard Coast Line Industries, two holding companies which controlled a number of railroads operating in the Eastern United States. Initially only a holding company itself, the subsidiaries that made up CSX Corporation were gradually merged, with this process completed in 1987. CSX Transportation formally came into existence in 1986, as the successor of Seaboard System Railroad. In 1999, CSX Transportation acquired approximately half of Conrail, in a joint purchase with competitor Norfolk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railroad Bridges In Pennsylvania
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles ( rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Homestead Grays Bridge
The Homestead Grays Bridge, also known as the (Homestead) High Level Bridge, was built in 1936 and spans the Monongahela River between Homestead Borough and the southernmost tip of Pittsburgh's Squirrel Hill neighborhood. It is notable as the first bridge to incorporate the Wichert Truss, which uses a quadrilateral shape over each support, into its design. This made the truss statically determinate, so that forces in the structural members could be calculated. There are very few surviving Wichert Truss bridges, including one other example in Pittsburgh, the Charles Anderson Memorial Bridge. History The bridge was dedicated on Saturday November 20, 1937, having cost the county of Allegheny $2.75 million to build and originally carried four highway lanes and two streetcar tracks of Pittsburgh Railways Company. It replaced the 1897 Brown's Bridge (Homestead and Highland Bridge) which was upstream and had linked Brown's Hill Rd on the north bank and Second Avenue between Ann Stree ...
