History Of Pittsburgh's South Side
In 1763, George III of the United Kingdom, King George III provided John Ormsby (Pittsburgh), John Ormsby approximately along the south bank of the Monongahela River as payment for his services during the French and Indian War. The land was then divided into four boroughs: South Pittsburgh, Birmingham, East Birmingham, and Ormsby. The four boroughs were annexed into the City of Pittsburgh in 1872. These areas, collectively, provided for the foundation of the South Side (Pittsburgh), South Side as it is known today. General James O'Hara (quartermaster), James O'Hara and Major Isaac Craig, the pioneers of the glass industry in Pittsburgh, opened the first glass factory in the county in South Side, near the present-day Duquesne Incline parking area. By the early-to-mid 19th century, South Side was known as the center of glass production, glass industry in the United States of America. In 1876, there were about 76 glass factories in the neighborhood. The location was so nationally r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wabash Bridge (Pittsburgh)
The Wabash Bridge was a railroad bridge across the Monongahela River at Pittsburgh. It was constructed between 1902 and 1904 by railroad magnate George J. Gould for his Wabash Pittsburgh Terminal Railway. The Wabash Bridge carried rail traffic from the elaborate Wabash Terminal in downtown Pittsburgh to the Wabash Tunnel in Mt. Washington. The rail cars were from the Wabash-Pittsburg Terminal Railroad, an ill-fated venture by George Jay Gould to compete with the Pennsylvania Railroad in Pittsburgh. After less than half a century, the Wabash was considered a “hard luck” bridge, haunted by its history, and an eyesore. In 1946, a fire destroyed the terminal. The bridge had become a useless hulk, and was dismantled two years later. Some of its steel was melted down for use in the Dravosburg Bridge, which was being built in 1948. History Construction of the bridge began in 1902. The two ends of the bridge were begun from opposite banks before being joined in the middle. On Oct ...

Liberty Tunnel
The Liberty Tunnels (also known as the Liberty Tubes) are a pair of tunnels located in Pittsburgh, Pennsylvania, United States that allow motorists to travel between the South Hills of Pittsburgh and the city, beneath Mt. Washington. The tunnels were vital in the expansion of the South Hills suburbs by providing a direct route to the city, eliminating the time-consuming task of navigating around or over Mt. Washington and its inclines. Opening in 1924, the Liberty Tunnels are the longest automobile tunnel in the City of Pittsburgh. Design The tunnels were designed by Amos D. Neeld, who would also supervise the construction of the adjoining Liberty Bridge, which gives travelers a way to cross the Monongahela River after passing through the tunnels. The design was two vertical wall horseshoe profile tunnels, each consisting of two lanes of traffic and a sidewalk. The sidewalks, being minimally used and in disrepair, were removed during a renovation in the 1970s in order to w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liberty Bridge (Pittsburgh)
The Liberty Bridge, completed in 1928, connects downtown Pittsburgh, Pennsylvania, to the Liberty Tunnels and the South Hills neighborhoods beyond. It crosses the Monongahela River and intersects Interstate 579 (the Crosstown Boulevard) at its northern terminus. History The Liberty Bridge is a steel cantilever bridge and was constructed as the missing link between downtown Pittsburgh and the Liberty Tunnel, which had been constructed four years earlier in 1924 as a link to the South Hills. The bridge opened on March 27, 1928, following a vehicle parade from the southern suburbs of the city, which crossed the Smithfield Street Bridge and proceeded through downtown before ending at the southern end of the new bridge. It was designed by George S. Richardson and cost $3,456,000 to build. It is 2663' 3/16" long, though the main span is 448' and the water clearance is 44.4'. It was renovated in 1982 by the Dick Corporation, at a cost of $32 million. Fire On September 2, 2016 the L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John A
Sir John Alexander Macdonald (January 10 or 11, 1815 – June 6, 1891) was the first prime minister of Canada, serving from 1867 to 1873 and from 1878 to 1891. The dominant figure of Canadian Confederation, he had a political career that spanned almost half a century. Macdonald was born in Scotland; when he was a boy his family immigrated to Kingston in the Province of Upper Canada (today in eastern Ontario). As a lawyer, he was involved in several high-profile cases and quickly became prominent in Kingston, which elected him in 1844 to the legislature of the Province of Canada. By 1857, he had become premier under the colony's unstable political system. In 1864, when no party proved capable of governing for long, Macdonald agreed to a proposal from his political rival, George Brown, that the parties unite in a Great Coalition to seek federation and political reform. Macdonald was the leading figure in the subsequent discussions and conferences, which resulted in the Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suspension Bridge
A suspension bridge is a type of bridge in which the deck (bridge), deck is hung below suspension wire rope, cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical ''suspender cables'' that transfer the Structural load#Live load, imposed loads, transient load, live and Structural load#Dead load, dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework. The suspension cables must be anchored at each end of the bridge, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wire Rope
Steel wire rope (right hand lang lay) Wire rope is several strands of metal wire twisted into a helix forming a composite ''rope'', in a pattern known as ''laid rope''. Larger diameter wire rope consists of multiple strands of such laid rope in a pattern known as ''cable laid''. In stricter senses, the term ''wire rope'' refers to a diameter larger than , with smaller gauges designated cable or cords. Initially wrought iron wires were used, but today steel is the main material used for wire ropes. Historically, wire rope evolved from wrought iron chains, which had a record of mechanical failure. While flaws in chain links or solid steel bars can lead to catastrophic failure, flaws in the wires making up a steel cable are less critical as the other wires easily take up the load. While friction between the individual wires and strands causes wear over the life of the rope, it also helps to compensate for minor failures in the short run. Wire ropes were developed starting with min ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Fire Of Pittsburgh
The Great Fire of Pittsburgh occurred on April 10, 1845, destroying a third of the city and causing between $6 million and $12 million in damage. While having little effect on the culture of the city except to spur further growth, it would provide a temporal reference point for the remainder of the century and beyond. Background The city of Pittsburgh originated in the mid-18th century as a French military settlement at the confluence of the Allegheny and Monongahela rivers. It remained relatively small through the end of that century, but the 19th century brought rapid growth of a population made up of natives of English, Scottish, and German descent, as well as large numbers of immigrants. By 1845, its population topped 20,000 and was swelled by crews completing the new Pennsylvania Canal. The city’s growth had been haphazard, resulting in a patchwork of the rich homes and businesses of the city fathers intermingled with tightly packed abutting wooden structures housing its ...

Smithfield Street Bridge
The Smithfield Street Bridge is a lenticular truss bridge crossing the Monongahela River in Pittsburgh, Pennsylvania, USA. The bridge was designed by Gustav Lindenthal, the engineer who later designed the Hell Gate Bridge in New York City. The Smithfield Street Bridge was built between 1881 and 1883, opening for traffic on March 19, 1883. It was widened in 1889 and widened again in 1911. The bridge has been designated a National Historic Civil Engineering Landmark, a National Historic Landmark, and has a Historic Landmark Plaque from the Pittsburgh History and Landmarks Foundation. History The present bridge is the third bridge at the site and remains the second oldest steel bridge in the United States. In 1818, a wooden bridge was built across the Monongahela by Louis Wernwag at a cost of $102,000. This bridge was destroyed in Pittsburgh's Great Fire of 1845. The second bridge on the site was a wire rope suspension bridge built by John A. Roebling. Increases in both bridge tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
