It's an old railroad bridge over the Hudson...a massively over-engineered thing, because steel (vs. iron) was a newer material, and nobody was really sure how well it was going to hold up over time. Now it's a walking route that connects the pedestrian/bike trails on both sides of the river. The views are STUNNING...but it's utterly exposed, no shelter to hide behind/under, so not sure if Zara would like it.
