1. Herald Square’s Beautiful Abandoned Skybridge
On West 32nd street in Herald Square is one of the city’s most impressive skybridges. It is a remnant of Gimbel’s Department Store, which opened in this location in 1910 and competed with Macy’s. Gimbel’s built the green skybridge to connect the store to its next door annex.
Though it was almost destroyed when the owners of the Gimbel’s building changed, it still intact (albeit decrepit and obsolete). You can see its interior here, and learn more about other New York City sky bridges.
