10. The Suspended Monorail
Photo from New York City Parks Photo Archive.
The AMF dual rail I-Beam monorail was a suspended mass transit system that transported visitors around the fairgrounds. In the photo above, taken next to New York State Pavilion, you’ll notice “humps swelling up from the ground at the lake area near the highways.” According to Facebook commenter Helmut Eppich, those are apparently the pylon foundations for monorail support — or what’s left of them at least.
