The Joy of the 14th Street Elevator
The new 14th Street elevator is now open (and beautiful). Next time you visit the High Line, give it a try--you'll be transported from street level to High Line level by way of a vivid yellow-green car. It's just to the West of the High Line stairs on 14th Street.
Another elevator is located at 16th Street. A list of all the High Line access points is here.
