Workers reportedly installed an escalator on the 101st floor of One World Trade Center. A photographer captured the escalator dangling high above Lower Manhattan, as workers lifted it with a crane mounted on top of the building. The image, posted by Reddit user jacknappier, shows a spectacular feat of engineering, and provides a dizzying dose of vertigo.
One World Trade Center is already the tallest building in NYC.
The escalator photo comes less than a week after the first section of a 408-foot spire was hoisted atop the building.
UPDATE: ThyssenKrupp Elevator company reached out to HuffPost and provided some more extraordinary photos from the day. Check them out below:
