This one is pretty good, even for highway-saturated New Jersey:
Where is it? Maybe this overlay will help:
Pretty much at the border of northern and central New Jersey. The Garden State Parkway, with US 9 in parallel, crosses highway 440. To the east, 440 enters Staten Island on the Outerbridge Crossing, and eventually meets up with our friend I-278 near the Goethal's Bridge Crossing. To the west, it crosses I-95 (New Jersey Turnpike) and becomes I-287. It's really not as complicated as it sounds. Really.
