How do you travel by car through a country that has thousands of cities ? Are you travelling city to city ? No.
You travel through states. You *mostly* won't need to worry about the city you need to get to at first because states are *mostly* connected by major routes.
You've got time to think how to get to the city when you're in the destination state.
In OpF Cities are the little towns. If there are too many of them to get a solution just search for a way to use big sectors (states) instead. Search the main route and try to put all alternative routes into sectors.
If this is possible you'll get a much simpler solution at first. When you got ur destination sector, you need a 2nd calculation how to get to the destination city, but the advantage is that you only need to calculate within a single sector.
It's like guessing a certain number somebody chooses out of 1-1000. How to do it ? Start guessing in big terms (states/sectors): "Is it 500 ?"
"Naah, it's lower" (This is your main target sector)
"Is it 250 ?"
"Lower"
"125?"
"Higher"
"188?" (125 + 63)
"Close, but higher"
"190?"
"Yep"

Just an idea. It depends how good you can organize cities on the map + their connections into bigger sectors.
