I tried to create a city map (huge siege). It has a river in the middle dividing it apart.
1. The part that won't be accessible only in a scenario where winter frost comes.
2. I wanted to prevent units from crossing the river just the way they used to, by entering it.
3. I planned river going units to be used (either for crossing or fire support)
So, I used water hexes to draw the river more or less wide and they do not accept bridges... I did a trick, I put river into water hexes where I wanted a bridge, and they did appear (not very nice tho). Ah yes, but they don't work!
Ships can cross - all fine, but land units cannot because - I guess - the base hex type is water. And of course supply access is also broken.
Would it be too difficult to allow bridges over water (at least over lake or shallow)? Also it would be logical to check it against supply, so if someone destroys the bridge supply link should be broken.
I might risk the wild idea for the future to threat bridges as infrastructure like a supply hex so strategic bombing could damage it and builders could repair it. Handling the value from 0-10 as "condition": damaged bridge could limit supply throughput, and limit units by weight (heavy/light thread etc)
