Ohiopyle Highway Bridge
The Ohiopyle Highway Bridge is a structure that carries two lanes of Pennsylvania Route 381 Youghiogheny River in Ohiopyle, Pennsylvania The span, which opened in 1975, is the third to be located in the vicinity. An original 19th-century covered bridge was replaced by a Pratt truss bridge around 1900. Because of a low-clearance underpass located directly adjacent to its southern approach, this structure proved to be obsolete once the automobile replaced the train as the primary method of tourism in the years following World War II. Although already scheduled for replacement, the discovery of a major fatigue crack sealed the fate of this structure, leading the way for the present girder bridge to be erected.

Ohiopyle, Pennsylvania
Ohiopyle is a borough in Fayette County, Pennsylvania, United States. The population was 38 at the 2020 census. While Ohiopyle has a tiny year-round population, it is often filled with tourists on the weekend, who come for the outdoor recreation opportunities at the surrounding Ohiopyle State Park, as well as the Great Allegheny Passage bicycle trail which connects with the Chesapeake and Ohio Canal towpath trail to form a continuous 335-mile off-road trail from Pittsburgh, Pennsylvania to Washington, D.C. The borough of Ohiopyle is served by the Uniontown Area School District. History Native Americans The first known group of people to inhabit the Ohiopyle area were the Monongahela, a clan of the Mound Builders. These Native Americans disappeared from the scene just as European colonists were beginning to arrive in North America. As the east coast was settled, the Native Americans who lived closer to the Atlantic Ocean were exterminated or forced to flee to the west. Variou ...

Girder Bridge
A girder bridge is a bridge that uses girders as the means of supporting its deck. The two most common types of modern steel girder bridges are plate and box. The term "girder" is often used interchangeably with "beam" in reference to bridge design. However, some authors define beam bridges slightly differently from girder bridges. A girder may be made of concrete or steel. Many shorter bridges, especially in rural areas where they may be exposed to water overtopping and corrosion, utilize concrete box girder. The term "girder" is typically used to refer to a steel beam. In a beam or girder bridge, the beams themselves are the primary support for the deck, and are responsible for transferring the load down to the foundation. Material type, shape, and weight all affect how much weight a beam can hold. Due to the properties of the second moment of area, the height of a girder is the most significant factor to affect its load capacity. Longer spans, more traffic, or wider spacing o ...

Pratt Truss
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 ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ohiopyle Low Bridge
The Ohiopyle Low Bridge is an American structure that carries the Great Allegheny Passage trail across the Youghiogheny River in Ohiopyle, Pennsylvania. History and architectural features The span was originally opened in 1912 as part of the last major railroad built in Pennsylvania. It served the Western Maryland Railway's expansion from Cumberland, Maryland to Connellsville, Pennsylvania and was one of two bridges to cross a meandering section of the Youghiogheny River in Ohiopyle. The original deck girder bridge was located near the center of the tiny community of Ohiopyle and opened the rugged region to tourism. By the 1960s, the importance of the Low Bridge had been dramatically reduced. The automobile had replaced the train as the method of transportation to what was now Ohiopyle State Park, and the narrow clearance of Pennsylvania Route 381's passage under the bridge would lead to bottlenecks during the summer tourism season. The Western Maryland Railway was incorpor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Allegheny Passage
The Great Allegheny Passage (GAP) is a rail trail between Pittsburgh, Pennsylvania and Cumberland, Maryland. Together with the C&O Canal towpath, the GAP is part of a route between Pittsburgh and Washington, D.C., that is popular with through hikers and cyclists. History The GAP follows former right-of-way of the Baltimore and Ohio Railroad, Pittsburgh and Lake Erie Railroad, Union Railroad, and Western Maryland Railway. The first section of the GAP— near Ohiopyle—opened in 1986. The section between Woodcock Hollow and Cumberland opened on December 13, 2006. The GAP was completed in 2013 when the section between West Homestead and Point State Park in Pittsburgh opened. The completion project was named ''The Point Made'', reflecting the fact that it was now possible to reach Point State Park from Washington, D.C. Celebrations took place on June 15, 2013. With its opening, Pennsylvania became the state with the most rail trails—, with more under development. The ove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Confluence Railroad Bridge
In geography, a confluence (also: ''conflux'') occurs where two or more flowing bodies of water join to form a single channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river (main stem); or where two streams meet to become the source of a river of a new name (such as the confluence of the Monongahela and Allegheny rivers at Pittsburgh, forming the Ohio); or where two separated channels of a river (forming a river island) rejoin at the downstream end. Scientific study of confluences Confluences are studied in a variety of sciences. Hydrology studies the characteristic flow patterns of confluences and how they give rise to patterns of erosion, bars, and scour pools. The water flows and their consequences are often studied with mathematical models. Confluences are relevant to the distribution of living organisms (i.e., ecology) as well; "the general pattern ownstream of confluencesof increasing stream flow and decreasing ...

Bridges In Fayette County, Pennsylvania
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.
