W.D. Mansfield Memorial Bridge
The W.D. Mansfield Memorial Bridge, commonly known as the Dravosburg Bridge, is a cantilever bridge that carries vehicular traffic across the Monongahela River between McKeesport, Pennsylvania and Dravosburg, Pennsylvania. It is a high-level bridge, passing over railyard, industrial sites, and Route 837, to connect Fifth Avenue in McKeesport and Richland Avenue in Dravosburg. History This structure replaced the low-level 1889 Dravosburg-Reynoldton Bridge. The steel from the Wabash Bridge (Pittsburgh), demolished in 1948, was used in the construction of this bridge. As built, the Mansfield Bridge carried trolley tracks of Pittsburgh Railways route 56 ''McKeesport via 2nd Avenue''. The trolley line was replaced by a bus on September 5, 1963. The bridge is named for McKeesport politician William D. Mansfield, who served as an Allegheny County Commissioner and later as a State Senator.

Monongahela River
The Monongahela River ( , )—often referred to locally as the Mon ()—is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed August 15, 2011 river on the Allegheny Plateau in North Central West Virginia, north-central West Virginia and Greater Pittsburgh, Southwestern Pennsylvania. The river flows from the confluence of its west and east forks in north-central West Virginia northeasterly into southwestern Pennsylvania, then northerly to Pittsburgh and its confluence with the Allegheny River to form the Ohio River. The river's entire length is navigable via a series of locks and dams. Etymology The Unami language, Unami word ''Monongahela'' means "falling banks", in reference to the geological instability of the river's banks. Moravian Church, Moravian missionary David Zeisberger (1721–1808) gave this account of the naming: "In the Lenape language, Indian tongue the name of this river was ''Mechmenawungihilla'' (alter ...

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 McKee' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cantilever Bridge
A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers). For small footbridges, the cantilevers may be simple beam (structure), beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete. The steel truss cantilever bridge was a major engineering breakthrough when first put into practice, as it can span distances of over , and can be more easily constructed at difficult crossings by virtue of using little or no falsework. Origins Civil engineer, Engineers in the 19th century understood that a bridge that was continuous across multiple supports would distribute the loads among them. This would result in lower stresses in the girder or truss and meant that longer spans could be built. Several 19th-century engineers patented continuous bridges with hinge points mid-span.

Wabash Bridge (Pittsburgh)
The Wabash Bridge was a railroad bridge across the Monongahela River at Pittsburgh. It was constructed between 1902 and 1904 by railroad magnate George J. Gould for his Wabash Pittsburgh Terminal Railway. The Wabash Bridge carried rail traffic from the elaborate Wabash Terminal in downtown Pittsburgh to the Wabash Tunnel in Mt. Washington. The rail cars were from the Wabash-Pittsburg Terminal Railroad, an ill-fated venture by George Jay Gould to compete with the Pennsylvania Railroad in Pittsburgh. After less than half a century, the Wabash was considered a “hard luck” bridge, haunted by its history, and an eyesore. In 1946, a fire destroyed the terminal. The bridge had become a useless hulk, and was dismantled two years later. Some of its steel was melted down for use in the Dravosburg Bridge, which was being built in 1948. History Construction of the bridge began in 1902. The two ends of the bridge were begun from opposite banks before being joined in the middle. On Oct ...

Pittsburgh Railways
Pittsburgh Railways was one of the predecessors of Pittsburgh Regional Transit. It had 666 PCC cars, the third largest fleet in North America (after Toronto (745) and Chicago (683)). It had 68 streetcar routes, of which only three (until April 5, 2010, the 42 series, the 47 series, and 52) are used by the Port Authority as light rail routes. With the Port Authority's Transit Development Plan, many route names will be changed to its original, such as the 41D Brookline becoming the 39 Brookline. Many of the streetcar routes have been remembered in the route names of many Port Authority buses (e.g. 71 series). History 1895 to 1905 was a time of consolidation for the numerous street railways serving Pittsburgh. On July 24, 1895 the Consolidated Traction Company (CTC) was chartered and the following year acquired the Central Traction Company, Citizens Traction Company, Duquesne Traction Company and Pittsburgh Traction Company and converted them to electric operation.

Pennsylvania State Senate
The Pennsylvania State Senate is the upper house of the Pennsylvania General Assembly, the Pennsylvania state legislature. The State Senate meets in the State Capitol building in Harrisburg. Senators are elected for four year terms, staggered every two years such that half of the seats are contested at each election. Even numbered seats and odd numbered seats are contested in separate election years. The president pro tempore of the Senate becomes the lieutenant governor of Pennsylvania in the event of the sitting lieutenant governor's removal, resignation or death. In this case the president pro tempore and lieutenant governor would be the same person. The Pennsylvania Senate has been meeting since 1791. The president of the Senate is the lieutenant governor, who has no vote except to break a tie vote. Qualifications Senators must be at least 25 years of age. They must be a U.S. citizen and a PA resident four years, and a resident of that district one year prior to their ele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

McKeesport Connecting Railroad Bridge
The McKeesport Connecting Railroad Bridge, also known as the Riverton Bridge, is a bridge that spans the Monongahela River between McKeesport, and Duquesne, Pennsylvania. History The bridge connected the U.S. Steel Duquesne Works and the National Tube Works in McKeesport and was used by Pennsylvania Union Railroad which is owned and operated by Transtar, Inc., the railroad division of U.S. Steel. In the late 1950s/early 1960s the large blast furnace Dorothy (named for the U.S. Steel president's wife) was built to supply steel to both plants, replacing many smaller furnaces. In the 1980s, during the decline of the American steel industry, both mills were closed and razed. The Bridge remained unused for several years, until 2007, when it became part of the Great Allegheny Passage bike trail from the C&O Canal Towpath in Cumberland MD to Pittsburgh PA. The bridge is next to the McKeesport – Duquesne vehicular bridge. See also *List of crossings of the Monongahela River This ...

Bridges Over The Monongahela River
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.
