In Philadelphia driving this is called the "New Jersey" problem -- you miss your turn or your exit and all of a sudden you're on a bridge heading to New Jersey with no real idea of how you got there.
My friends call it getting “Newarked”. If we visit NJ for any reason and miss any turn in Bergen, Hudson, Essex, or Union county, and try to use road signs to get back on track, we end up at Newark Airport Terminal C. It’s like the entire NJ roadway system is a feed network for United Departures.
