The High Line is an elevated freight rail line transformed into a public park on Manhattan’s West Side.

Founded in 1999 by community residents, Friends of the High Line fought for the High Line’s preservation and transformation at a time when the historic structure was under the threat of demolition.

There have been a number of these sorts of conversions lately that have the potential to change what our assumptions are about what it means to live in an urban environment.

A similar project has been proposed to cover over parts of one of Los Angeles’ major freeways to create a park.
