Smithton Low-Level Bridge
The Smithton Low-Level Bridge is a structure that carries Pennsylvania Route 981 across the Youghiogheny River between South Huntingdon Township and Rostraver Township, just south of Smithton, Pennsylvania. The previous structure on this site was a cantilever bridge built in 1900 to connect Smithton, which was then thriving due to its brewery, with residences on the west bank of the river; a state court ruled in favor of petitioners who demanded the creation of a bridge, but ordered that they contribute $1,200 in construction costs. Until the completion of the Smithton High-Level Bridge in 1956 (which eventually became part of busy Interstate 70), this structure was one of the most important vehicular crossings of the river. In 1986, the original bridge was replaced by a modern girder bridge.

Youghiogheny River
The Youghiogheny River , or the Yough (pronounced Yok ) for short, is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed August 15, 2011 tributary of the Monongahela River in the U.S. states of West Virginia, Maryland, and Pennsylvania. It drains an area on the west side of the Allegheny Mountains northward into Pennsylvania, providing a small watershed in extreme western Maryland into the tributaries of the Mississippi River. Youghiogheny is a Lenape word meaning "a stream flowing in a contrary direction".

I-70
Interstate 70 (I-70) is a major east–west Interstate Highway in the United States that runs from I-15 near Cove Fort, Utah, to a park and ride lot just east of I-695 in Baltimore, Maryland, and is the fifth-longest Interstate in the country. I-70 approximately traces the path of U.S. Route 40 (US 40, the old National Road) east of the Rocky Mountains. West of the Rockies, the route of I-70 was derived from multiple sources. The Interstate runs through or near many major cities, including Denver, Topeka, Kansas City, St. Louis, Indianapolis, Columbus, Pittsburgh, and Baltimore. The sections of the Interstate in Missouri and Kansas have laid claim to be the first Interstate in the United States. The Federal Highway Administration (FHWA) has claimed the section of I-70 through Glenwood Canyon, Colorado, completed in 1992, to be the last piece of the Interstate Highway System, as originally planned, to open to traffic. The construction of I-70 in Colorado and Utah is c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cantilever Bridges In The United States
A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In the southe ...

Bridges Over The Youghiogheny River
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.

Road Bridges In Pennsylvania
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", which ...

Historic American Engineering Record In Pennsylvania
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Wheeling And Lake Erie Railway (1990)
The Wheeling and Lake Erie Railway is a Class II regional railroad that provides freight service, mainly in the areas of Northern Ohio and Western Pennsylvania. It took its name from the former Wheeling and Lake Erie Railway, most of which it bought from the Norfolk and Western Railway in 1990. History Original Wheeling and Lake Erie Railway (1880-1949) The W&LE Railroad began standard gauge operations under investor Jay Gould in 1880. It's mainline ran from Wheeling to Zanesville to Cleveland, and it ran freight and passenger trains primarily between those cities. It eventually completed a route connecting Pittsburgh, PA (Rook) and Toledo, Ohio. Most freight traffic on the line was coal and iron ore, with general merchandise also making up a significant portion. Passenger service ended in 1940 just before the start of World War II. Brewster begin serving as headquarters of the Wheeling and Lake Erie Railway in 1914. Service from Huron to Massillion, Ohio was opened on Janu ...

Banning Railroad Bridge
The Banning Railroad Bridge is a structure that carries the Wheeling and Lake Erie Railway across the Youghiogheny River in Perry Township, Fayette County, Pennsylvania. The bridge was constructed in 1930 by the American Bridge Company as part of the major railroad to be built in Pennsylvania. Like the Speers Railroad Bridge along the same route, the structure uses a "K-truss" design that is extremely uncommon outside of the Great Plains states. Although once part of a critical connection between the Pittsburgh industrial region and the Western Maryland Railroad, today the bridge sees light traffic and is mainly used for the transportation of coal.
