Bridges over lakes

[T-72]

It's not a very big deal, but when you generate a map with lots of lakes, the map generator tends to build bridges over the lakes. IRL, the roads would mostly bypass the lake ,especially if the area is rural and the lake could easily be bypassed (you know what I mean).

Are there any specific map generator parameters which would allow you to have a lots of lakes with roads mostly bypassing the lakes?
