Do any airbridges move vertically to match arrival/departure halls? One of the things that always baffles me is that airports almost always have the arrivals and departures sections on different levels, but that you exit the aircraft into the departures hall. In some airports this leads to long walks along labyrinthine corridors to customs.

Now it seems to me that one could easily raise and lower the other end of the bridge to match the hall being used. Domestic flights could exit directly onto the arrivals level, and international to the customs. Yes, this would increase the complexity of the bridges, but much less than the reduction in complexity of the rest of the airport layout while eliminating many escalators and elevators.

Does anyone know an airport that does something like this?
JFK's Terminal 7 (British Airways Terminal) had (no more) some gates with this feature. The terminal-side of the bridge moved vertically down for disembarkation, and up for boarding. You can see a photo in this post on flyertalk.com. Below is a comparison for the old/new systems:
