Allegheny River
The Allegheny River ( ) is a long headwater stream of the Ohio River in western Pennsylvania and New York. The Allegheny River runs from its headwaters just below the middle of Pennsylvania's northern border northwesterly into New York then in a zigzag southwesterly across the border and through Western Pennsylvania to join the Monongahela River at the Forks of the Ohio on the "Point" of Point State Park in Downtown Pittsburgh, Pennsylvania. The Allegheny River is, by volume, the main headstream of both the Ohio and Mississippi Rivers. Historically, the Allegheny was considered to be the upper Ohio River by both Native Americans and European settlers. The shallow river has been made navigable upstream from Pittsburgh to East Brady by a series of locks and dams constructed in the early 20th century. A 24-mile long portion of the upper river in Warren and McKean counties of Pennsylvania and Cattaraugus County in New York is the Allegheny Reservoir, created by the erectio ...

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 ...

Bridges In Armstrong 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. Etymology The '' Oxford English Dictionary'' traces the origin of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Truss Bridges In The United States
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as '' nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary for ...

Sergeant Carl F
Sergeant (abbreviated to Sgt. and capitalized when used as a named person's title) is a rank in many uniformed organizations, principally military and policing forces. The alternative spelling, ''serjeant'', is used in The Rifles and other units that draw their heritage from the British light infantry. Its origin is the Latin , 'one who serves', through the French term . The term ''sergeant'' refers to a non-commissioned officer placed above the rank of a corporal, and a police officer immediately below a lieutenant in the US, and below an inspector in the UK. In most armies, the rank of sergeant corresponds to command of a squad (or section). In Commonwealth armies, it is a more senior rank, corresponding roughly to a platoon second-in-command. In the United States Army, sergeant is a more junior rank corresponding to a squad- (12 person) or platoon- (36 person) leader. More senior non-commissioned ranks are often variations on sergeant, for example staff sergeant, g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foxburg Bridge (2008)
The Foxburg Bridge carries PA 58 over the Allegheny River between Armstrong County, Pennsylvania and Clarion County, Pennsylvania in Foxburg, Pennsylvania, USA. History The new bridge was completed alongside the old Foxburg Bridge which was demolished to allow the pedestrian walkway to be added. The project began in 2007 and was due to end in 2009 but the bridge opened to traffic ahead of schedule. The cost of the project was $10.1 million.

Parker, Pennsylvania
Parker is a city located in Armstrong County, Pennsylvania, United States. It is in the extreme northwestern portion of the county. The population was 840 at the 2010 census. The city was named for Judge John Parker, a lead surveyor of Lawrenceburg and founder/owner of Parker's Landing, the two villages combined to create Parker. Parker is sometimes referred to as the "Smallest City in the USA." Parker was incorporated as a city on March 1, 1873, by special state legislation in the midst of the northwestern Pennsylvania oil boom. The new municipality was called "Parker" and made up the earlier villages of Parker's Landing (on the Allegheny River) and Lawrenceburg (on the bluff above the river). Residents assumed that Parker would quickly become a major population center, and at the height of the oil boom, the population of Parker grew to over 20,000. The boom quickly went bust, however, and by the 1880s the "city" returned to its historic small village size—a population of ap ...
