I visited it yesterday, with GAPIMNY, and saw the plans turned into reality. A stone walkway running in the middle of the park guides the strollers. The slots cut into the stone at various places echo the pattern of railway ties, much of which remains by both sides of the walk. The same pattern is repeated in the many benches placed at strategic points for interesting views. The walkway widens into common spaces at a few points. One such space, provided with theater seating, overlooks 10th Avenue.
The plants flanking the walkway are ones commonly found growing along abandoned train tracks. According to the park website, many of the species originally found growing on these tracks were incorporated into the landscaping. Grasses, perennials, shrubs. They give the oxymoronic impression of lush neglect.
The tracks were deliberately built to run through the blocks, instead of over a main road. So the present park shoulders its way through some buildings, giving a level view of third or fourth floor windows of offices and homes, as well as some low rooftops. One could have seen such a view from some vantage point in some building, but before the park opened none could have seen so continuous a view suspended in mid-air. The art photos on the park website do not do justice to the novelty of this view. Perhaps only a film can.
