The Staple Street Skybridge is a blogger/instagrammer fav for a good reason. It’s situated in a throwback, cobblestoned alley of a street with a few doorways and an especially charming facade at 4 Staple Street. The bridge is made of cast iron with big picture windows. It was designed in 1907 by Robertson & Potter for the New York City Hospital House of Relief to connect the main building with its annexed expansion across the street. The two buildings were converted to residential and now the bridge connects a townhouse to a loft across the street and was/is on the market for a cool $35 million.
