For most of its entire length, 66th Street runs as a westbound thoroughfare – the exception being right here. For reasons unknown (to me, at least) this one block is wider, has two lanes for driving westbound and east bound, an extra lane for parking, and a large median right in the middle. The center sidewalk is lined with as many parking meters as trees. The Parks Department marks this otherwise-vacant stretch as part of the Greenstreets program.
It would almost make more sense to treat these as two separate streets. The southern half is lined with a massive high-rise complex complete with balconies and white brick. Meanwhile, the northern side is far more classic and architecturally conservative with its 5-story apartment buildings nestled up next to each other. Of course, that dichotomy goes straight to hell at the end of the block when a second, this time glass-sheathed, high-rise takes over the quaint buildings on the northern side.
