Although every New Yorker has heard of Park Avenue in Manhattan, and has perhaps even walked along it, many of them probably have no idea the extensive history behind this well-recognized thoroughfare. Prior to 1887, Park Avenue did not exist and instead this now sought over street was known as Fourth Avenue. The name Park Avenue derives from the garden malls that, although at times inconsistently, run down the center of avenue. What some may not know is why these “parks” exist in the first place. Before Park Avenue was a recognizable name, the street was sought after because of its wider than average width due to the avenue having been a thoroughfare to steam locomotives. Because of a series of accidents and urging from the City, the locomotives that once ran along the street were moved below street level in 1872. In order to mask the unsightly, noxious smelling steam vents that ran down the middle of the streets, garden mall spaces were built and planted with greenery.
