Mon Incline Caption on the back of the photograph reads, “The Monongahela Incline was opened May 28, 1870; the first Incline in Pittsburgh. Eventually, Pittsburgh had 17 Inclines. Now, only 2 remain; the Duquesne Incline and the Monongahela Incline. The Monongahela Incline was first operated by the Pittsburgh Railways Company, and in 1964 it was taken over by the Port Authority who operate it at the present time. It runs from Carson Street to the top of Mt. Washington which is a residential area. One-half Million People, commuters and visitors ride this incline each year.” The Monongahela Incline climbs a 35 percent grade, one of the steepest incline planes in the world. In 1970 it was declared a historic structure by the Pittsburgh History and Landmarks Foundation. In 1982 Port Authority made improvements to the incline with the replacement of car bodies, improved access, and renovated stations. In 1994 electrical and mechanical components of the machinery were replaced, trackway lighting was installed, and an addition was added to the upper station. (Detre Library & Archives, Sen.
