Bridge Dilemma

Now that I've made what I feel are enough river sections, the next step is to make (or buy) some bridges. Thinking about it, I can go two ways:

1. I can build or buy a bridge model that can be plunked down anywhere along the river segments.

2. I can make a small river segment, like I did for the river forge, that incorporates a bridge.

There are pros and cons to both.

Free standing bridge:
Pros: putting it anywhere means that a road can cross the river at any point. I don't have to force the road to fit a location along the river. Second, I can make various bridges to fit various games: European-looking bridges for WW2 or fantasy games; more generic or jungle-looking bridges for my fictional Gambusia campaign.
Cons: Won't look very pretty. Second, I will have to make sure that a bridge will span any point along a river. There may be the problem that a bridge is much longer than the width of the river section. That is more of an aesthetic issue, but a bridge that is too short will just look stupid. Also, if the banks are irregular in height (which they are to varying degrees) the bridge won't sit very well on it.

River segment with built-in bridge:
Pros: Will look much nicer. Will eliminate some of the problems listed in the above cons regarding free-standing bridges.
Cons: May be a big problem when there is a road crossing a river at a point where a bridge segment cannot be placed. I would have to force the road to conform to the river or reconfigure the river segments to conform to the road. Second, would take a little longer to build them. As much as I really enjoy building terrain, I'm getting a little burned out on it and want to finally do some gaming.

I have been combing the internet and both methods are used. I have noticed that the built-in bridges tend to be on tables that use terrain modules. I am not going in that direction. It might be that the free standing bridge is the way to go.

Any comments or suggestions are greatly welcomed.
