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 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 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.
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.
