Elevator from 17 green to 18 tee at Pittsburgh Field Club....a bit odd because from afar it looks like a 40-foot tall green-painted right angle sitting on top of a slope.
Angled funicular behind the 18th green at Lookout Point in Ontario...
Then lots of northeast courses have neat bridges like Winchester, Sleepy Hollow, Charles River, etc. We used to have a great one at Tedesco, but those holes went out of play in the mid-30s, and the huge bridge was taken down.
