At that point, it's a pedestrian path from Henry Street to the east (at left in photo), and does not continue to the west through green space and the Brooklyn Queens Expressway (see map below).
Why did it catch my eye? Because, in August 2014, Forest City Ratner spokeswoman Ashley Cotton told NY 1, in Atlantic Yards Project to Now Be Called 'Pacific Park Brooklyn':
..."This is an incredibly important name to signify there'll be eight acres of publicly accessible open space, and it connotates Pacific Street, which is a beautiful street that runs from either side of the project up into Prospect Heights, down to Boerum Hill and all the way down to the water."Um, it doesn't. Not the most important thing, but do remember that the logic is bogus. More importantly, as far as I've been ale to learn, the partnership has not paid for the use of demapped Pacific Street for the project.
