There's a few of these around the suburb-y metro Detroit area. They're nice to bike on, and they haven't seemed awful to drive, but they do still do "divide neighborhoods" quite well, which is unfortunate
The first time I went to the Netherlands I walked from Schiphol airport to the center of Amsterdam and it was an easy but amazing experience. Walking from JFK to Manhattan is a completely possible walk in terms of distance (I usually do better than a 20 minute pace on the flats so it takes only half a day) but when I think of the battle with the infrastructure you'd have to do it's like an Arnold Schwarzenegger movie.
