High Line is a 2.4km long part of a former freight railroad stretching over Manhattan. It was built in 1930 as a part of West Side Improvement project for enhancing the infrastructure. It was elevated 9m in the air, therefore it elimininated dangerous trains off the streets of Manhattan. Due to the increase in interstate ground cargo transport in the fifties the train transportation came to a halt in 1980. In 1992 a court ordered demolishion of the railroad remnants. The sight of the rusty tracks covered with wildflowers, grass and even trees caught the attention of a group of local artists who sprung a campain against the destruction.
Joshua David and Robert Hammond founded a community Friends of the High Line (FHL) and started a New York City funded competition. Winning design came from the architects Diller Scofidio + Renfro and will be completed in this year but is open for public since 2009. The park is embodied by an integration of naturalistic landscape (in cooperation with landscape architect James Field) and meandering concrete pathways.
