Streams do engineer units help in crossing streams?

[pavane]

I remember building some bridges over streams once, I think it was in the Minsk Campaign game. Some areas are really full of marches, streams and rivers. Once the ground conditions change to Mud and you are really counting every hour waiting for that panzer division that´s been slugging from reserve to arrive into the battle, it surely helps to bridge a stream near a crucial crossroad or something similar. 

But it surely is rarely seen to bridge streams and the engineers always have a better job to do (bridging rivers, helping with digging-in, laying mines etc..)
