Washington Crossing Bridge (Pittsburgh)
right The Washington Crossing Bridge, commonly known as the Fortieth Street Bridge, is an arch bridge that carries vehicular traffic across the Allegheny River between the Pittsburgh neighborhood of Lawrenceville and the suburb of Millvale. History Erected between 1919 and late 1924, and officially opened on December 29, 1924, the Washington Crossing Bridge was originally built to accommodate two lanes of traffic and one streetcar line. Its estimated cost upon completion was $2,344,000. A 1982 re-decking allowed for the creation of a reversible third automobile lane. The bridge received its name because it is located at a historically significant site pertaining to George Washington's military career.

Bridges Completed In 1921
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.

Former CSX Transportation Bridges
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

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] |
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] |
31st Street Bridge
The William Raymond Prom Memorial Bridge, commonly known as the 31st Street Bridge, is an arch bridge that carries vehicular traffic across the Allegheny River between the Pittsburgh neighborhoods of Troy Hill and the Strip District. The bridge passes over, but does not serve, Washington's Landing, which is connected to the mainland by the 30th Street Bridge. Sidewalks along the bridge feature viewing platforms. History The bridge was built in 1927–1928 to replace an earlier through truss bridge aligned with 30th Street. This earlier bridge was built in 1887 but was destroyed by fire on July 8, 1921. The 1887 bridge itself replaced a two span iron truss which was destroyed by a flood in 1882. A cable suspension footbridge was provided as a crossing whilst the new 31st Street bridge was being constructed. The bridge was due to close on Tuesday January 31, 2006 for a proposed $27 million refurbishment which would take two years. It eventually closed on February 14, 2006 and ...

P&W Subdivision
The P&W Subdivision is a railroad line owned and operated by CSX Transportation, the Allegheny Valley Railroad (AVR), and the Buffalo and Pittsburgh Railroad (BPRR) in the U.S. state of Pennsylvania. The line runs from Rankin north through Pittsburgh to West Pittsburg (near New Castle) along a former Baltimore and Ohio Railroad line, once the Pittsburgh and Western Railroad. The line begins in Rankin at the Pittsburgh Subdivision, almost directly under the Rankin Bridge, and runs along the east (right) shore of the Monongahela River. It meets the AVR's W&P Subdivision near the Glenwood Bridge in Glenwood, and continues near the river to near Greenfield. A line once branched out to the Pittsburgh B&O train station here, on the current Eliza Furnace Trail. Then the line turns north away from the river, and continues into Junction Hollow and through the Schenley Tunnel which goes under Oakland to Bloomfield. There it crosses and connects with the Norfolk Southern Railway's P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herrs Island, Pittsburgh
Herrs Island, also known as Washington's Landing, is an island in the Allegheny River in Pittsburgh in the U.S. state of Pennsylvania. It is officially considered part of the Troy Hill neighborhood. Rehabilitation As a result of the industrial activity, Herrs Island was a brownfield site. By the 1970s, most industrial activity on the island had left. During the 1980s and 1990s, a major redevelopment effort was undertaken after a long study of best uses. The island is now a showcase project of urban redevelopment for the City of Pittsburgh. It is now a mixed-use community, home to townhomes and business parks, a marina, the Three Rivers Rowing Association, and the Western Pennsylvania Conservancy. The northern portion of Herrs Island contains a small park with tennis courts, a public lawn, and manicured landscapes. A section of the Three Rivers Heritage Trail loops around the island, offering a crushed-gravel pedestrian path with several scenic overlooks of the Allegheny River ...
