The 33rd Street Railroad Bridge is a truss bridge that carries the Allegheny Valley Railroad on the P&W Subdivision over the Allegheny River that connects downtown Pittsburgh, Pennsylvania to Herrs Island, Pittsburgh, United States.
The Allegheny River was first crossed at this point by a railroad bridge built in 1884 [1] by the Iron City Bridge Works, which moved to Pittsburgh from Cincinnati in 1856. [2]
This was replaced by the B&O bridge in 1921. [3]

Downtown Pittsburgh, colloquially referred to as the Golden Triangle, and officially the Central Business District, is the urban downtown center of Pittsburgh, Pennsylvania, United States. It is located at the confluence of the Allegheny River and the Monongahela River whose joining forms the Ohio River. The triangle is bounded by the two rivers.
Allegheny City was a municipality that existed in the U.S. state of Pennsylvania from 1788 until it was annexed by Pittsburgh in 1907. It was located north across the Allegheny River from downtown Pittsburgh, with its southwest border formed by the Ohio River, and is known today as the North Side. The city's waterfront district, along the Allegheny and Ohio rivers, became Pittsburgh's North Shore neighborhood.
The Pittsburgh and Lake Erie Railroad, also known as the "Little Giant", was formed on May 11, 1875. Company headquarters were located in Pittsburgh, Pennsylvania. The line connected Pittsburgh in the east with Youngstown, Ohio in the Haselton neighborhood in the west and Connellsville, Pennsylvania to the east. It did not reach Lake Erie until the formation of Conrail in 1976. The P&LE was known as the "Little Giant" since the tonnage that it moved was out of proportion to its route mileage. While it operated around one tenth of one percent of the nation's railroad miles, it hauled around one percent of its tonnage. This was largely because the P&LE served the steel mills of the greater Pittsburgh area, which consumed and shipped vast amounts of materials. It was a specialized railroad deriving much of its revenue from coal, coke, iron ore, limestone, and steel. The eventual closure of the steel mills led to the end of the P&LE as an independent line in 1992.
The Western Maryland Railway was an American Class I railroad (1852–1983) that operated in Maryland, West Virginia, and Pennsylvania. It was primarily a coal hauling and freight railroad, with a small passenger train operation.

The Coraopolis Bridge is a girder bridge over the back channel of the Ohio River connecting Grand Avenue on Neville Island to Ferree Street in Coraopolis, Pennsylvania. It opened in 1995 to replace a structure of historic significance. The original Pratt/Bowstring/Pennsylvania through truss spans, designed by Theodore Cooper, were formerly the (third) Sixth Street Bridge, spanning the Allegheny River, in downtown Pittsburgh, and were built in 1892 by the Union Bridge Company. They were floated downstream by the Foundation Company in 1927 rather than being demolished when the bridge was removed to enable construction of the present (fourth) Three Sisters (Pittsburgh) Sixth Street Self-anchored suspension bridge. However, by the late 1980s, the old bridge could no longer support traffic volumes and was replaced by a newer structure.
The Hot Metal Bridge is a truss bridge in Pittsburgh, Pennsylvania, that crosses the Monongahela River. The bridge consists of two parallel spans on a single set of piers: the former Monongahela Connecting Railroad Bridge, built in 1887, on the upstream side and the former Hot Metal Bridge, built in 1900, on the downstream side. The Monongahela Connecting Railroad Bridge carried conventional railroad traffic, while the Hot Metal Bridge connected parts of the J&L Steel mill, carrying crucibles of molten iron from the blast furnaces in ladle transfer cars to the open hearth furnaces on the opposite bank to be converted to steel. During World War II 15% of America's steel making capacity crossed over the Hot Metal Bridge, up to 180 tons per hour. The upstream span was converted to road use after a $14.6 million restoration, and opened by Mayor Tom Murphy with a ceremony honoring former steel workers on June 23, 2000. The bridge connects 2nd Avenue at the Pittsburgh Technology Center in South Oakland with Hot Metal Street in the South Side. The downstream span reopened for pedestrian and bicycle use in late 2007 after two years of work. The Great Allegheny Passage hiker/biker trail passes over this bridge as it approaches Pittsburgh's Golden Triangle area.
The Glenwood B&O Railroad Bridge is a truss bridge in Pittsburgh, Pennsylvania, which carries Allegheny Valley Railroad's W&P Subdivision over the Monongahela River.

Grant Street Station, also known as the B&O Pittsburgh Terminal, was a passenger rail station on Grant Street downtown Pittsburgh, Pennsylvania. The Baltimore and Ohio Railroad (B&O) announced plans for it on May 3, 1955, after selling the original B&O Station bordering the Monongahela River to the state for construction of Interstate 376. It opened in 1957 to serve commuter rail traffic; all intercity traffic continued to use the Pittsburgh and Lake Erie Railroad's (P&LE) station. Grant Street was the last such privately owned train station built in Pennsylvania.
