Between 51st and 57th St in Midtown is a funny thing: a walkway that cuts through the belly of office buildings and leads off to sidewalks past stop signs, where vehicles must stop for you footfall.
The signed “6½ Avenue” had been, according to this New York Times article, an “open secret” for years — but last year it became a city-sanctioned legit “street.” It’s kinda fun.

I pass by there quite frequently and always wonder why it is there or how it got there. Had no idea it was a legit ‘secret’ street! haha, funny 😀
