West End Bridge
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). The bridge was designed by George S. Richardson. 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 p ...

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" prior to its completion. History The bridge was constructed from 1958-1963 by PennDOT, and opened for traffic on 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 named "The Bridge to Nowhere" because the main span was finished in 1963, but due to delays in acquiring the right of way 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 s ...

Allegheny County Airport
Allegheny County Airport is in West Mifflin, Pennsylvania, United States, 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.

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 provide cash flow to the creditor (e.g. repay the principal (i.e. amount borrowed) of the bond at the maturity date and interest (called the coupon) over a specified amount of time.) The timing and the amount of cash flow provided varies, depending on the economic value that is emphasized upon, thus giving rise to different types of bonds. 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 Share capital, 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. ...

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 are 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 that 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 construction industry contributes significantly to many countries' gross domestic products (GDP). Global expenditure on construction activities was about $4 trillion in 2012. In 2022, expenditure on the construction industry exceeded $11 trillion a year, equivalent to about 13 percent of global GDP. This spending was forecasted to rise to around $14.8 trillion in 2030. The construction industry promotes economic development and brings many non-monetary benefits to many countries, but it is one of the most hazardous industries. For exampl ...

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. There are several types of truss bridges, including some with simple designs that were among the first bridges designed in the 19th and early 20th centuries. A truss bridge is economical to construct primarily 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 the strength to mainta ...
