Kiskiminetas River
The Kiskiminetas River (commonly referred to as the Kiski by locals) is a tributary of the Allegheny River, approximately long, in Western Pennsylvania in the United States. The region stretching from the northern side of Harmar Township, Pennsylvania to the Kiskiminetas towns is often referred to by the locals as the Alle-Kiski Valley after the rivers. Course The Kiskiminetas River is formed at Saltsburg, on the border between Westmoreland and Indiana counties, by the confluence of the Conemaugh River and Loyalhanna Creek. It flows northwest in a meandering course past Avonmore, Apollo, Vandergrift, Hyde Park and Leechburg. It joins the Allegheny River near Freeport at Schenley, approximately northeast of Pittsburgh. The Kiski-Conemaugh watershed includes much of the historic coal-producing region of Western Pennsylvania. The water quality is considered degraded by numerous abandoned mine drainages in its upper reaches and tributaries, leading to on-going effort ...

Nearby hamlets like "Old Town" and "Jacksonville" were among the earliest developed areas.

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 ...

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 railway) without blocking the path 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, 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 in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the word ''bridge' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
