Brady Street Bridge
The Brady Street Bridge, also known as the South 22nd Street Bridge, was a steel bowstring arch bridge in Pittsburgh, Pennsylvania, which crossed over the Monongahela River at South 22nd Street. Its main span was a tied arch with a suspended road deck, with two through-truss side spans, carrying two traffic lanes between Brady Street on the Pittsburgh side and South 22nd Street on the south side. Approach viaducts were built at either end. The bridge was built by the Schultz Bridge and Iron Company. The Brady Street Bridge closed on May 3, 1976, but the new Birmingham Bridge was still being constructed and would not be open for another 14 months. Over two years later on May 29, 1978, the old bridge span was blasted into the Monongahela River. During the cleanup process that followed, railings from its remains were rescued by the Pittsburgh History and Landmarks Foundation and utilized in the construction of the Station Square station Station Square station is a transit sta ...

Monongahela River
The Monongahela River ( , )—often referred to locally as the Mon ()—is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed August 15, 2011 river on the Allegheny Plateau in North Central West Virginia, north-central West Virginia and Greater Pittsburgh, Southwestern Pennsylvania. The river flows from the confluence of its west and east forks in north-central West Virginia northeasterly into southwestern Pennsylvania, then northerly to Pittsburgh and its confluence with the Allegheny River to form the Ohio River. The river's entire length is navigable via a series of locks and dams. Etymology The Unami language, Unami word ''Monongahela'' means "falling banks", in reference to the geological instability of the river's banks. Moravian Church, Moravian missionary David Zeisberger (1721–1808) gave this account of the naming: "In the Lenape language, Indian tongue the name of this river was ''Mechmenawungihilla'' (alter ...

Bridges Completed In 1896
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. Etymology The ''Oxford English Dictionary'' traces the origin of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures Demolished In 1978
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demolished Bridges In The United States
Demolition (also known as razing, cartage, and wrecking) is the science and engineering in safely and efficiently tearing down of buildings and other artificial structures. Demolition contrasts with deconstruction, which involves taking a building apart while carefully preserving valuable elements for reuse purposes. For small buildings, such as houses, that are only two or three stories high, demolition is a rather simple process. The building is pulled down either manually or mechanically using large hydraulic equipment: elevated work platforms, cranes, excavators or bulldozers. Larger buildings may require the use of a wrecking ball, a heavy weight on a cable that is swung by a crane into the side of the buildings. Wrecking balls are especially effective against masonry, but are less easily controlled and often less efficient than other methods. Newer methods may use rotational hydraulic shears and silenced rock-breakers attached to excavators to cut or break through wo ...

Historic American Buildings Survey In Pennsylvania
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Road Bridges In Pennsylvania
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", which ...

Bridges In Pittsburgh
The Bridges of Pittsburgh play an important role in the city's transportation system. Without bridges, the Pittsburgh region would be a series of fragmented valleys, hillsides, river plains, and isolated communities. A 2006 study determined that, at the time, Pittsburgh had 446 bridges. With its proximity to three major rivers and countless hills and ravines, Pittsburgh is known as ''"The City of Bridges"''. History Pittsburgh's first river bridges, made of wood and long since replaced, opened in 1818 at Smithfield Street and 1819 at Sixth Street (then St. Clair Street). The city's oldest in-service bridge is the current Smithfield Street Bridge, which opened in 1883; it was designated a National Historic Landmark in 1976. Pittsburgh waged a massive road and bridge building campaign from 1924 to 1940; most of Pittsburgh's oldest major bridges date from this period. The coming of the Interstate Highway System triggered more construction in the second half of the twentieth centur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pittsburgh Post-Gazette
The ''Pittsburgh Post-Gazette'', also known simply as the PG, is the largest newspaper serving metropolitan Pittsburgh, Pennsylvania. Descended from the ''Pittsburgh Gazette'', established in 1786 as the first newspaper published west of the Allegheny Mountains, the paper formed under its present title in 1927 from the consolidation of the ''Pittsburgh Gazette Times'' and ''The Pittsburgh Post''. The ''Post-Gazette'' ended daily print publication in 2018 and has cut down to two print editions per week (Sunday and Thursday), going online-only the rest of the week. In the 2010s, the editorial tone of the paper shifted from liberal to conservative, particularly after the editorial pages of the paper were consolidated in 2018 with '' The Blade'' of Toledo, Ohio. After the consolidation, Keith Burris, the pro-Trump editorial page editor of '' The Blade'', directed the editorial pages of both papers. Early history ''Gazette'' The ''Post-Gazette'' began its history as a four-page w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Station Square (PAT Station)
Station Square station is a transit station on Pittsburgh Regional Transit's light rail network. It is the last Transit station on the south side of the Monongahela River. This station is named for the nearby Station Square mixed-use development and opened in 1985. Many South Hills residents access the facility using light rail service, and employees at the adjacent major office park, which includes the headquarters of WESCO International are also major beneficiaries of the stop. Several thousand commuters each weekday also rely on this stop as a park-and-ride station, using either a 160 space Pittsburgh Regional Transit lot or the privately owned garage in Station Square. The station's close proximity to the Monongahela Incline, South Busway, Carson and Smithfield Streets, and the large parking facilities and boat docks of the Gateway Clipper Fleet at Station Square add to the station's inter-modal transportation value.

Pittsburgh History And Landmarks Foundation
The Pittsburgh History & Landmarks Foundation (PHLF) is a nonprofit organization founded in 1964 to support the preservation of historic buildings and neighborhoods in Pittsburgh, Pennsylvania, USA. In 1966, PHLF established the Revolving Fund for Preservation with a $100,000 grant from the Sarah Scaife Foundation. PHLF used the grant to purchase, restore and renovate historic inner-city properties primarily in the North Side and South Side neighborhoods of Pittsburgh, which were rented or sold to low- and moderate-income families. Allegheny County Survey PHLF was the first historic preservation group in the nation to undertake a countywide survey of architectural landmarks, which Co-Founders Arthur P. Ziegler Jr. and James D. Van Trump did in 1965. The foundation's historic plaque program was begun in 1968, and since that time it has awarded over 500 plaques to designate significant historical structures within Allegheny County.
