Bridge over the North Fork

With the roads generally OK, I put in some crops, marked where my houses will be and marked a crossing of the North Fork River. The first object (houses, bridges, etc.) that I put in was a pontoon bridge.  I am trying to decide whether or not to make the crossing to Bennett's Bayou (as per the historical map) or make it outward to other parts of Missouri (as per the modified campaign map).

I am also looking at the big open space between the hills and town to the north and river to the south. Originally, I thought I might make it a swamp, but the elevation is a little high for that. I might make it some kind of big, nasty, brushy, flood plain.
