To the right side of the ditch is one airport (8NC9) with a grass runway and to the left side of the ditch is another separate airport (0A7) with a grass/paved runway. There is a taxiway bridge that aircraft can taxi across to get from one to the other. Both are completely separate airports as considered by the FAA.
Anything else out there like this? Two airports (with two identifiers/names/etc) but connected? I know there are many cases of airports that are really two separate operations, maybe a military base/runway and civilian side/runway that are connected... but they're still just considered one airport.
