Interstate 376 (I-376) is a major auxiliary route of the Interstate Highway System in the US state of Pennsylvania, located within the Allegheny Plateau. It runs from I-80 near Sharon south and east to a junction with the Pennsylvania Turnpike in Monroeville, after having crossed the Pennsylvania Turnpike at an interchange in Big Beaver. The route serves Pittsburgh and its surrounding areas and is the main access road to Pittsburgh International Airport (PIT). Portions of the route are known as the Beaver Valley Expressway, Southern Expressway, and Airport Parkway. Within Allegheny County, the route runs along the majority of the Penn-Lincoln Parkway, known locally as Parkway West and Parkway East. It is currently the ninth-longest auxiliary Interstate route in the system and second only to I-476 within Pennsylvania.

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.
