Arroyo, Pennsylvania
Arroyo was a lumber town in western Pennsylvania in the United States that also had an extensive hide tanning industry. It was founded by Thomas Irwin and located in the township of Spring Creek Township, Elk County, Pennsylvania, Spring Creek, on the Clarion River, and from Ridgway, Pennsylvania, Ridgway. The Arroyo Bridge Company was incorporated in April, 1883, with F. Shaffner, E. M. Rogers, C. H. Smith, James B. Wicks and Charles Millen, directors. The object was to bridge the Clarion at Arroyo. The Arroyo Bridge, located in Elk County, Pennsylvania, Elk County, was originally constructed in 1882 by the Arroyo Bridge Company, which consisted of a group of local residents who operated it as a toll bridge until 1899. Elk County purchased the bridge and replaced it in 1901, when it became the site for many summer social events and dances. The Arroyo Bridge (1901-2004), a three-span, metal Pratt Truss bridge, long, built by the Nelson and Buchanan company of Pittsburgh and ...

Lumber
Lumber is wood that has been processed into dimensional lumber, including beams and planks or boards, a stage in the process of wood production. Lumber is mainly used for construction framing, as well as finishing (floors, wall panels, window frames). Lumber has many uses beyond home building. Lumber is sometimes referred to as timber as an archaic term and still in England, while in most parts of the world (especially the United States and Canada) the term timber refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut. Lumber may be supplied either rough- sawn, or surfaced on one or more of its faces. Beside pulpwood, ''rough lumber'' is the raw material for furniture-making, and manufacture of other items requiring cutting and shaping. It is available in many species, including hardwoods and softwoods, such as white pine and red pine, because of their low cost. ''Finished lumber'' is supplied in standard sizes, mostly ...

Toll Bridge
A toll bridge is a bridge where a monetary charge (or ''toll'') is required to pass over. Generally the private or public owner, builder and maintainer of the bridge uses the toll to recoup their investment, in much the same way as a toll road. History The practice of collecting tolls on bridges harks back to the days of ferry crossings where people paid a fee to be ferried across stretches of water. As boats became impractical to carry large loads, ferry operators looked for new sources of revenue. Having built a bridge, they hoped to recoup their investment by charging tolls for people, animals, vehicles, and goods to cross it. The original London Bridge across the river Thames opened as a toll bridge, but an accumulation of funds by the charitable trust that operated the bridge (Bridge House Estates) saw that the charges were dropped. Using interest on its capital assets, the trust now owns and runs all seven central London bridges at no cost to taxpayers or users. In t ...

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 ...
