Flame,
I was contemplating a bridge across our creek, but it can't have piers within the banks without massive permitting.
I priced telephone poles on Facebook and Craigslist and found some really cheap ones available. They are already water and UV treated, so they should last a long time.
I was just going to run two 40-footers in parallel across the creek. (If you can't balance on that, then you have to wade!)
If you don't cross deep water, then you could probably add a 100' bridge at a pretty low cost. You might even be able to make a floating bridge - but I don't know about leaching creosote, etc. into a pond?
This type of bridge would be very functional but ugly. I don't know if that would be an option in your situation.
It would not be an option for Rusto! His wife can see the whole pond from their deck.
