New York City’s sidewalks are so packed, pedestrians are literally taking to the skies. Well, sort of. Completed in 2014, the High Line is a 1.45-mile-long linear park stretching from Gansevoort Street in the Meatpacking District to West 34th Street, between 10th and 12th Avenue. Fashioned from an abandoned elevated railroad from the 1930s, the garden of greenery is peppered with planting accents, including underpasses through wooden architectural displays, with broader design elements that provide spaces to sit with a view of the street below. A morning visit will have you mingling with local joggers, commuters and dog walkers, while a steady stream of tourists tends to build up through the afternoon. Sitting 30 feet about the street, at its northern end, the High Line offers a bird’s-eye view into the city’s latest real estate development project, Hudson Yards, the next housing destination for New York’s power brokers. For the voyeurs, take a peek into the lives of local New Yorkers via the apartments and high-rise office buildings flanking the runway, before finding a spot overlooking the traffic racing below on 10th Avenue. In the pipeline, is a 420-foot offshoot extending along West 30th Street and over 10th Avenue, of which park organizers said the focus is going to be on horticulture, event programming and public art.
