Fifteenth Avenue Bridge
The Fifteenth Street Bridge is a girder bridge across the Youghiogheny River connecting the Pittsburgh industrial suburbs of Port Vue and McKeesport, Pennsylvania. The 1995 structure replaced a 1906 truss bridge. The bridge's length is significantly longer than that of several surrounding structures because its crosses both the river and a large water treatment facility. The Youghiogheny River Trail, a portion of the Cumberland, Maryland-to-Pittsburgh Pittsburgh ( ) is a city in the Commonwealth (U.S. state), Commonwealth of Pennsylvania, United States, and the county seat of Allegheny County, Pennsylvania, Allegheny County. It is the most populous city in both Allegheny County and Wester ... Great Allegheny Passage uses the bridge's pedestrian lanes. Through McKeesport, the trail features a designated right of way, while it is officially signed through city streets in Port Vue. As of 2005, the bridge officially became known as the Senator Albert V. “Bud” Belan Bri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Great Allegheny Passage
The Great Allegheny Passage (GAP) is a rail trail between Pittsburgh, Pennsylvania and Cumberland, Maryland. Together with the C&O Canal towpath, the GAP is part of a route between Pittsburgh and Washington, D.C., that is popular with through hikers and cyclists. History The GAP follows former right-of-way of the Baltimore and Ohio Railroad, Pittsburgh and Lake Erie Railroad, Union Railroad, and Western Maryland Railway. The first section of the GAP— near Ohiopyle—opened in 1986. The section between Woodcock Hollow and Cumberland opened on December 13, 2006. The GAP was completed in 2013 when the section between West Homestead and Point State Park in Pittsburgh opened. The completion project was named ''The Point Made'', reflecting the fact that it was now possible to reach Point State Park from Washington, D.C. Celebrations took place on June 15, 2013. With its opening, Pennsylvania became the state with the most rail trails—, with more under development. The o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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", whic ...

Bridges Completed In 1995
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 the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keystone Subdivision
The Keystone Subdivision is a railroad line owned and operated by CSX Transportation in the U.S. states of Maryland and Pennsylvania. The line runs from Cumberland, Maryland, west to McKeesport, Pennsylvania, (near Pittsburgh) along a former Baltimore and Ohio Railroad (B&O) line. The line includes the well-known Sand Patch Grade over the Allegheny Mountains. The east end of the Keystone Subdivision is at Viaduct Junction in Cumberland, where it meets the Cumberland Terminal Subdivision at the east end of the Cumberland Viaduct. The west end is at Sinns, on the west (left) side of the Youghiogheny River at Liberty, where it continues as the Pittsburgh Subdivision through Pittsburgh and on to West Pittsburg. The Keystone Subdivision also joins with the S&C Subdivision at Rockwood, Pennsylvania. Amtrak's '' Capitol Limited'' uses the Keystone Subdivision. History The Pittsburgh and Connellsville Railroad (P&C) was first incorporated in 1837, but did not succeed in rai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
P&LE Liberty Boro Bridge
The P&LE Liberty Boro Bridge is a girder bridge across the Youghiogheny River connecting the Pittsburgh industrial suburbs of Liberty and McKeesport, Pennsylvania. In 1968, the Pittsburgh & Lake Erie Railroad undertook a major construction project in conjunction with the B&O Railroad to clear tracks from downtown McKeesport. These tracks caused traffic congestion and posed a safety hazard. As a result, both this bridge and the nearby P&LE McKeesport Bridge were created to direct rail traffic to the west bank of the river, which featured a less confusing street grid. While its sister structure is a truss bridge that crosses the river parallel to a highway bridge, the Liberty Boro Bridge appears relatively utilitarian and crosses the river at a nearly diagonal angle. The structure currently serves the Pittsburgh-to- Cumberland, Maryland CSX CSX Transportation , known colloquially as simply CSX, is a Class I freight railroad operating in the Eastern United States and the Can ...

Jerome Street Bridge
The Jerome Street Bridge is an arch bridge across the Youghiogheny River connecting the east and west banks of the Pittsburgh industrial suburb of McKeesport, Pennsylvania. The bridge is a rare steel crescent arch bridge. A crescent arch is formed when the intrados and extrados (the ribs) of the arch are not parallel, but instead form two different curves beginning and ending together. The ribs form a truss at the top of the arch and join together in a solid rib at each end. A crescent arch is a two-hinged arch, the ribs are further apart where the bending moment is greatest and close together at each hinge where it is minimized. History and architectural features This bridge was engineered by George S. Richardson. A Great Depression-era public works bond was provided to fund the creation of a new auto-centric four-lane highway bridge. The bridge was dedicated on May 3, 1938 and opened to traffic on May 4. Thousands of people attended the ceremony and parade to celebrate the new ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cumberland, Maryland
Cumberland is a U.S. city in and the county seat of Allegany County, Maryland. It is the primary city of the Cumberland, MD-WV Metropolitan Statistical Area. At the 2020 census, the city had a population of 19,076. Located on the Potomac River, Cumberland is a regional business and commercial center for Western Maryland and the Potomac Highlands of West Virginia. Historically Cumberland was known as the "Queen City", as it was once the second largest in the state. Because of its strategic location on what became known as the Cumberland Road through the Appalachians, after the American Revolution it served as a historical outfitting and staging point for westward emigrant trail migrations throughout the first half of the 1800s. In this role, it supported the settlement of the Ohio Country and the lands in that latitude of the Louisiana Purchase. It also became an industrial center, served by major roads, railroads, and the Chesapeake and Ohio Canal, which connected Cumberland to ...

McKeesport, Pennsylvania
McKeesport is a city in Allegheny County, Pennsylvania, United States. It is situated at the confluence of the Monongahela and Youghiogheny rivers and within the Pittsburgh metropolitan area. The population was 17,727 as of the 2020 census. It is Allegheny County's second biggest city after Pittsburgh. History Early history David McKee emigrated from Scotland and was the first permanent white settler at the forks of the Monongahela and Youghiogheny Rivers, the site of present-day McKeesport, in 1755. Around the time of the French and Indian Wars, George Washington often came to McKeesport to visit his friend, Queen Alliquippa, a Seneca Indian ruler. The Colonial Government granted David McKee exclusive right of ferrage over those rivers on April 3, 1769, called "McKee's Port". His son, John McKee, an original settler of Philadelphia, built a log cabin at this location. After taking over his father's local river ferry business, he devised a plan for a city to be called ...

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. 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 ...
