Hunter Station Bridge
The Hunter Station Bridge is a truss bridge that carries U.S. Route 62 (US 62) across the Allegheny River in rural Tionesta Township in Forest County, Pennsylvania. The structure was named for a railroad stop on the long defunct Ridgway & Oil City Railroad. The bridge features an unusual design, in which the roadway is built into the middle of the truss, as opposed to the bottom of the structure. This was done to prevent flooding from submerging the highway, which was relatively common before the upstream construction of the Kinzua Dam. In 1971, the bridge was reconstructed, several years after the completion of the dam.

Allegheny River
The Allegheny River ( ) is a long headwater stream of the Ohio River in western Pennsylvania and New York (state), 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, Pennsylvania, 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 County, Pennsylvania, Warren and McKean County, Pennsylvania, McKean counties of Pennsy ...

Pennsylvania Route 36
Pennsylvania Route 36 (PA 36) is a long state highway located in the U.S. state of Pennsylvania. The southern terminus is at PA 26 near the Hopewell Township community of Yellow Creek. The northern terminus is at PA 27 and PA 227 in Pleasantville. One of the longest and oldest highways in the commonwealth, PA 36 serves as a major connector between South Central and Northwestern Pennsylvania. In 1955, the highway was designated as the Colonel Drake Highway in honor of Edwin Drake. Route description Bedford and Blair counties PA 36 begins in the Bedford County hamlet of Yellow Creek at PA 26 along the Tussey Mountain range. The distance in Bedford County is brief as the highway enters Blair County and proceeds northward as the Woodbury Pike, intersecting several 800-series state highways like PA 866, PA 868, and PA 869. A short distance between Roaring Spring and the hamlet of McKee, PA 36 overlaps the east–west running PA 164. North of McKee, PA 36 become ...

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 t ...

Bridges Of The United States Numbered Highway System
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 ...

Western New York And Pennsylvania Railroad (2001)
The Western New York and Pennsylvania Railroad is a short-line railroad that operates freight trains in Western New York and Northwest Pennsylvania, United States. The company is controlled by the Livonia, Avon and Lakeville Railroad, with which it does not connect. It started operations in 2001 on the Southern Tier Extension, a former Erie Railroad line between Hornell, NY and Corry, PA, owned by the public Chautauqua, Cattaraugus, Allegany and Steuben Southern Tier Extension Railroad Authority (STERA). Through acquisitions and leases, the line was extended from Corry to Meadville, PA in 2002 and to Oil City, PA in 2006. In 2007, the WNY&P leased and sub-leased portions of the north-south Buffalo Line, a former Pennsylvania Railroad line mostly built by a predecessor of the defunct Western New York and Pennsylvania Railway. The two lines cross at Olean, NY. Operations The WNY&P operates a system centered on Olean, where it operates the ex-Erie yard just west of the crossing ...

Oil City Pennsylvania Railroad Bridge
The Oil City Pennsylvania Railroad Bridge is an American truss bridge that carries the Western New York and Pennsylvania Railroad (WNY&P) across the Allegheny River between Cranberry Township and Oil City, Pennsylvania. History and architectural features This bridge was originally built to serve the Pennsylvania Railroad as part of its Buffalo Line. WNY&P is the fourth owner of the structure. After the breakup of the Pennsy, Conrail took ownership of the line. The breakup of these companies resulted in the reassignment of operational rights to Norfolk Southern; the WNY&P took ownership in 2006 as it extended its trackage from Meadville, Pennsylvania to Oil City. Because the bridge once served as a major junction point for several Pennsylvania Railroad lines, it features a unique approach structure. One section ran from Oil City through Tidioute, Pennsylvania and then on to Warren, Pennsylvania. This line was operated until 1976. It was removed during the early 1980s. See also ...

Tionesta Bridge
The Tionesta Bridge is a girder bridge that carries U.S. Route 62 and Pennsylvania Route 36 across the Allegheny River in rural Forest County, Pennsylvania. The borough of Tionesta on the east bank of the river is connected with an unpopulated section of Tionesta Township on the west bank. This 1961 structure was the first girder bridge completed along the river between the edge of suburban Pittsburgh and Kinzua Dam. Over the last 30 years, many nearby structures were completed with a similar design; this bridge was rehabilitated in 1988.
