Monongahela Incline says
The Monongahela Incline, built by John Endres in 1870, is located near the Smithfield Street Bridge in Pittsburgh. It is the oldest continuously operating funicular in the USA. It is also one of two surviving inclines from the original 17 passenger-carrying inclines built in Pittsburgh starting in the late 19th century. Its lower station is across the street from the Station Square shopping complex, and is easily accessible from the light rail system at the Station Square station.
