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 ...

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 ...

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 th ...

History Andrew Carnegie had been discussing rail transport with other lines, but determined the best way to protect his interests was to control the rail line himself. Several smaller companies had constructed sections of the route. "Bear Creek Railroad (name changed to Shenango and Allegheny Railroad Co.) was incorporated in March 1865 for the purpose of moving ...

Chesapeake And Ohio Canal National Historical Park
The Chesapeake and Ohio Canal National Historical Park is located in the District of Columbia and the state of Maryland. The park was established in 1961 as a National Monument by President Dwight D. Eisenhower to preserve the neglected remains of the Chesapeake and Ohio Canal and many of its original structures. The canal and towpath trail extends along the Potomac River from Georgetown, Washington, D.C., to Cumberland, Maryland, a distance of . In 2013, the path was designated as the first section of U.S. Bicycle Route 50. The Chesapeake and Ohio Canal Construction on the Chesapeake and Ohio Canal (also known as "the Grand Old Ditch" or the "C&O Canal") began in 1828 and ended in 1850 when the canal reached Cumberland, far short of its intended destination of Pittsburgh, Pennsylvania. Occasionally there was talk of extending the 184.5-mile canal: for example, an 1874 proposal to dig an 8.4-mile tunnel through the Allegheny Mountains, and there was a tunnel built to connect with ...
