I don't think that'll be very practical. Taking into account the embark and disembark times, it would be highly inconvenient to have a small lake in the middle of two provinces. Take the great lakes of North America, for example. No one really invests in that area because no one would pass by that area. It's a cool geographic feature, but it's pretty impractical to the scale of warfare that we're looking at.
"As long as there are sovereign nations possessing great power, war is inevitable." Albert Einstein
"Giving up is not an option in war, for it proves one's incapability and incompetence as a leader." - Me (Little Racoon)
The time period of this game is set as WW2. In that time period there were already quite a few roads and bridges existing in the world. it is not like needing to cut a path through a jungle everywhere you want to go, and build a bridge as you go along. Bridge construction under fire wouldn't be very much fun, so the advance of troops would be planned to follow existing roads and bridges.
War is a game that is played with a smile. If you can't smile, grin. If you can't grin keep out of the way til you can. - Winston Churchill

Let's say you have infantry in a army and you come across a small bit of sea like in the UK, Exeter and Cardiff as one example, the infantry could have an ability to lay pontoon ridges, would take 45 mins to make and costs maybe 5k metal goods etc etc
