Field Operations and Diller Scofidio + Renfro unveiled plans for the ten-block path of the abandoned High Line between W. 20th and W. 30th Streets in New York's Chelsea neighborhood. The $71 million makeover includes a "thicket" of plants on the walkway up to W. 23rd Street, a wooden bleacher running alongside a block-long lawn with expansive city views, an empty billboard that will frame visitors' views of Tenth Avenue, a wooden walkover suspended above preserved grasses, and three blocks of wildflowers. The walkways will be narrow enough that pedestrian traffic could become congested, so joggers will have to look elsewhere to get their heart rates up. "You have to think of it as a garden, not as a street," said city-planning director Amanda Burden.
