I don't want to nit pick but Burnside's ridge is currently inaccurate.
Historically the Confederates had set up breastworks and rifle pits on the heights above the bridge. They also had a wall to the left of the bridge and a rock quarry to the right of it, currently none of these things can be found.
Also the Confederate treeline to the left of the bridge is too thick, Historically the bridge could be pretty well seen from the Confederate left.
Also, historically pretty much the whole river could be forded around the bridge, I understand that we can't for game-play purposes, however I suggest you make it fordable right under the bridge or just south of it. That way Union players have a better chance of getting across.
The geography of the map is wrong as well but I'm sure it's too late to change that, I will post it anyways just to show.
Below are some Pics showing my Suggestions and to show the Geography of the area irl.
