Allegheny Valley Railroad (1995)
The Allegheny Valley Railroad is a class III railroad that operates in Western Pennsylvania, and is owned by Carload Express, Inc. AVR acts as a feeder line connecting its many and varied customers to Class I railroads such as CSX Transportation (CSX) and Norfolk Southern Railway (NS), and regional lines such as the Buffalo and Pittsburgh Railroad (B&P) and the modern Wheeling and Lake Erie Railway (WE). The AVR's main line travels northward through Pittsburgh from an intersection with Norfolk Southern near Panther Hollow, before splitting in the Lawrenceville neighborhood. The AVR uses the P&W Subdivision segment of the line to cross the Allegheny River on the 33rd Street Railroad Bridge to interchange with the B&P in Bakerstown and/or Evans City. The other segment serves industries along the railroad's namesake valley between Pittsburgh and Arnold. The Glenwood B&O Railroad Bridge is utilized by it as part of its W&P Subdivision branchline from the city to Washi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The bridge is decorated with the seals representing the original 13 states of the United States and that of Allegheny County. 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.

Bridges Completed In 1921
A bridge is a structure built to Span (engineering), span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path 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, 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 in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of ...

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 used 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 cone 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 t ...

Bridges In Pittsburgh
The bridges of Pittsburgh play an important role in Transportation in Pittsburgh, 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, though that number has been disputed. 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 t ...

Railroad Bridges In Pennsylvania
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in tracks, which usually consist of two parallel steel rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and freight transport globally, thanks to its energy efficiency and potentially high speed.Rolling stock on rails generally encounters lower frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by diesel or electric locomotives. While railway transport is capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or animal power have existed since antiquity, but modern rail transport began with the invention of the steam locomotive in the United Kingdom at the beginning of the 19th c ...

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.

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 Riv ...
