We have run several posts on New York's celebrated High Line Park, the old railway lines on stilts to New York's meatpacking district that was converted to a park and opened to the public in June 2009, followed by a second extension in June 2011 that doubled its length to a mile.
New York City's Department of Parks has unveiled plans for the last phase of the Park. Like the previous phases, the final extension will be designed by James Corner Field Operations and Diller Scofidio + Refro. Current proposed concepts include an amphitheatre-like seating, or an open gathering space bordered by beds of wild flowers, a new irregularly spiraling staircase and a children's play area where support beams will be stripped and coated with bright yellow safety rubber, perfect to climb around on.
