The High Line is located on Manhattan's West Side. It runs from Gansevoort Street in the Meatpacking District to 34th Street, between 10th & 11th Avenues. Section 1 of the High Line, which opened to the public on June 9, 2009, runs from Gansevoort Street to 20th Street.

The High Line was built in the 1930s, as part of a massive public-private infrastructure project called the West Side Improvement. It lifted freight traffic 30 feet in the air, removing dangerous trains from the streets of Manhattan's largest industrial district. No trains have run on the High Line since 1980. Friends of the High Line, a community-based non-profit group, formed in 1999 when the historic structure was under threat of demolition. Friends of the High Line works in partnership with the City of New York to preserve and maintain the structure as an elevated public park.
