NPR : Project Gives Forgotten NYC Rail Line New, Lush Life: All Things Considered, April 10, 2006 · "In New York City, construction has begun on one of the most unusual and innovative parks in the nation. The High Line is an abandoned railroad overpass that spans 22 blocks on Manhattan's West Side and will become the nation's first elevated park.

The project will transform the rusting, forgotten structure into an urban promenade of lush parkland. It will run a mile and half through the city -- from Greenwich Village to Midtown Manhattan -- and hover three stories above the street.

On top of the elevated rail line, the sky opens up and the sounds of the city drop away. The rails are overgrown in sections with wild grasses and trees."
