West End Bridge (Pittsburgh)
The West End Bridge is a steel tied-arch bridge over the Ohio River in Pittsburgh, Pennsylvania, approximately below the confluence of the Allegheny and Monongahela Rivers. It connects the West End to the Chateau neighborhood on the North Side of Pittsburgh. The bridge was built from 1930 to 1932 primarily by the American Bridge Company (superstructure) and the Foundation Company (substructure). It was the longest tied-arch bridge in the world when completed, and just the second bridge to use tied-arch technology over a long span, after the Tacony–Palmyra Bridge (1929) in Philadelphia. The bridge was placed on the National Register of Historic Places in 1979 and the List of Pittsburgh History and Landmarks Foundation Historic Landmarks in 2001. As of 2016, the bridge and its surrounding approaches are undergoing some major reconstruction. The Riverlife Task Force conducted a competition in the spring of 2006 to design a pedestrian bridge across the Ohio attached to the We ...

Ohio River
The Ohio River is a long river in the United States. It is located at the boundary of the Midwestern and Southern United States, flowing southwesterly from western Pennsylvania to its mouth on the Mississippi River at the southern tip of Illinois. It is the third largest river by discharge volume in the United States and the largest tributary by volume of the north-south flowing Mississippi River that divides the eastern from western United States. It is also the 6th oldest river on the North American continent. The river flows through or along the border of six states, and its drainage basin includes parts of 14 states. Through its largest tributary, the Tennessee River, the basin includes several states of the southeastern U.S. It is the source of drinking water for five million people. The lower Ohio River just below Louisville is obstructed by rapids known as the Falls of the Ohio where the elevation falls in restricting larger commercial navigation, although in the 18th ...

Fort Duquesne Bridge
The Fort Duquesne Bridge is a steel bowstring arch bridge that spans the Allegheny River in Pittsburgh, Pennsylvania. It was colloquially referred to as "The Bridge to Nowhere". History The bridge was constructed from 1958-1963 by PennDOT, and opened for traffic October 17, 1969 with its predecessor Manchester Bridge (located closer to the tip of Point State Park) closing that same day (it was demolished in the autumn of 1970). The bridge was given the name "The Bridge to Nowhere" because the main span was finished in 1963, but due to delays in acquiring right of ways for the northern approach ramps, it did not connect on the north side of the Allegheny River. The total cost was budgeted at $5 million in 1962. The lack of approach ramps meant the bridge ended in midair, rendering it useless. On December 12, 1964, Frederick Williams, a 21-year-old chemistry major at the University of Pittsburgh from Basking Ridge, New Jersey, drove his 1959 Chrysler station wagon through the ...

Allegheny County Airport
Allegheny County Airport is in West Mifflin, Pennsylvania, 7 miles (11 km) southeast of Pittsburgh. It is the fifth-busiest airport in Pennsylvania following Philadelphia, Pittsburgh, Allentown, and Harrisburg. The airport is owned by the Allegheny County Airport Authority and is the primary FAA-designated reliever airport for Pittsburgh International Airport. Allegheny County Airport was dedicated on September 11, 1931. When it was completed, it was third-largest airport in the country and the only hard-surface airport in the country. It was historically the main entrance to metro Pittsburgh via air from its inception until June 1952, when the Greater Pittsburgh Airport (now Pittsburgh International Airport – KPIT) opened for commercial aviation. Like many historic municipal fields, Allegheny serves small and mid-sized private, corporate and commercial traffic well, but was not built to handle jet airliners.

Pennsylvania Route 51
Pennsylvania Route 51 (PA 51) is a major state highway in Western Pennsylvania. It runs for from Uniontown to the Ohio state line near Darlington, where it connects with Ohio State Route 14. PA 51 is the termination point for Pennsylvania Route 43, Pennsylvania Route 48 and Pennsylvania Route 88. The route is a major connection from Uniontown and the rest of Fayette County to Pittsburgh. The highway is four-lane highway south of Pittsburgh as it passes through Pittsburgh's South Hills, but narrows to a two-lane road through several boroughs along the Ohio River. It becomes four lanes again after passing Chippewa Township in Beaver County and continues to the Ohio border. In the South Hills, PA 51 (Saw Mill Run Boulevard), along with US 19, is one of the major routes in and out of Pittsburgh, as it provides access to several bridges and tunnels. PA 51 is one of the highways that enters the West End Circle, an intersection in the West End. Route description Fayet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Tenth Street Bridge
South Tenth Street Bridge, most often called the Tenth Street Bridge, but officially dubbed the Philip Murray Bridge, is a suspension bridge spanning the Monongahela River in Downtown Pittsburgh, Pennsylvania. It is the only cable suspension bridge in Allegheny County and its main span is the longest span on the Monongahela River. The bridge was renamed on Labor Day 2007 for Philip Murray, the first president of the United Steelworkers of America. The bridge was built in 1931–33 and connects South Tenth Street on the South Side to Second Avenue and the Armstrong Tunnel under the Bluff.

Bond Issue
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 Security (finance), securities, but the major difference between the two is that (capital) stockholders have an Equity (finance), 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 st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CONSTRUCTION OF THE MAIN SPAN, LOOKING WEST - West End-North Side Bridge, Spanning Ohio River, Approximately 1 Mile Downstream From Confluence Of Monongahela And Allegheny HAER PA,2-PITBU
Construction is a general term meaning the art and science to form objects, systems, or organizations,"Construction" def. 1.a. 1.b. and 1.c. ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0) Oxford University Press 2009 and comes from Latin ''constructio'' (from ''com-'' "together" and ''struere'' "to pile up") and Old French ''construction''. To construct is the verb: the act of building, and the noun is construction: how something is built, the nature of its structure. In its most widely used context, construction covers the processes involved in delivering buildings, infrastructure, industrial facilities and associated activities through to the end of their life. It typically starts with planning, financing, and design, and continues until the asset is built and ready for use; construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or decommissioning.

The route begins in the Golden Triangle of Pittsburgh as a limited-access highway, following the bank of the Allegheny and Ohio rivers around the Manchester neighborhood, passing north of Acrisure Stadium and west of PNC Park. While limited-access, the road becomes ''Ohio River Boulevard'', named for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...
