The Vision for NYC's High Line:

When the High Line is converted to public open space, you will be able to rise up from the streets and step into a place apart, tranquil and green. You will see the Hudson River, the Manhattan skyline, and secret gardens inside city blocks as you've never seen them before. You will move between Penn Station and the Hudson River Park, from the convention center to the Gansevoort Market Historic District, without meeting a car or truck. The High Line will be a promenade—a linear public place where you will see and be seen. You will sense New York's industrial past in the rivets and girders. You will perceive the future unrolling before you in an artfully designed environment of unprecedented innovation. It will be yours—public in the truest sense of the word. Public dollars helped build it in the 1930s. Public legislation empowers us to make it a place anyone can visit. It will be proof New York City no longer casts aside its priceless transportation infrastructure but instead creates bold new uses for these monuments to human power and ambition.*

The Vision for Atlanta's BeltLine:

Now imagine this same scenario in Atlanta encompassing 22 miles instead of 2.5!
