The High Line is an old freight rail line repurposed into a public park set above the streets of Manhattan’s West Side. I think it sets a wonderful standard for reconfiguring urban spaces in creative, constructive ways. Instead of tearing down old structures, why not give them a new lease of life while retaining their historic value? It’s great that the marks of a railroad e.g. converging tracks, bars on the tracks and side railings are preserved to some degree, as a reminder of its heritage and for interesting aesthetic effects. The gritty, industrial feel of the original structure and its surroundings (the historic Meatpacking district) is harmonized with natural elements like plants, water and grass patches for a truly unique urban experience.
