I came across this site by happenstance. Driving around the north hills of Pittsburgh (Shaler Township). Not sure what it was, but I thought it was pretty interesting.
Looks like a large loading bay facing the road.
The ramp at the back, going out of picture to the left crosses a stream, to (remains of) a small building by a railroad track. To the right is a large open field, presumably the former site of an industrial facility.The the main road (Rt. 8). I'm guessing this was some sort of depot for whatever factory used to be here.
