About river crossings...

[PanzerBob]

Another option would to edit a ford into a map and save in your maps. I generated a scenerio trying to see if the AI EN would try crossing a river on a stone bridge under fire or opt for a "ford" I "built" across the river with good cover each bank. I used beach and swamp terrain and got a reasonable effect. It was passable but like fords on a stream you can't just blaze across. In my scenario the AI EN tried both, they paid heavily on the bridge but had moderate success on my ford. The river was a 200m width.

Hope this might be of help.
