a garden path where the elevated train line once ran

The High Line is a 1.45-mile-long elevated, steel structure built in the 1930s to carry freight trains. When the High Line was built in the 1930s, these neighborhoods were dominated by industrial and transportation uses. These elevated tracks are no longer used in an industrial manner but instead are being transformed into a pathway with beautiful flowers and views of the Hudson river.  http://www.thehighline.org/
