The High Line is a former elevated freight rail line that runs for a mile and a half through the West side of lower Manhattan. Built in the 1930s, it was last used for rail traffic in 1980. Since then it has been considered a curiosity and an eyesore, fit to be demolished.
In 2002, a group of downtown businesses banded together to successfullly lobby the City of New York for the preservation of the High Line, and to create a promenade-style park winding through the lower West Side from it. The design team of Field Operations (landscape architects) and Diller Scofidio + Renfro (architects) was selected and construction of the new 6.7-acre park began in 2006.
