Eddie,
I am still wondering about the necessity of a bridge at all. I have a pond that is about 5 acres and was originally built by the state back in the 60’s to help control runoff. There is a constant spring creek feed into the pond and a constant flow out of the pond even during our drought years. I think the overflow pipe through the dam is about 8”. Our emergency spillway at the end of the dam is roughly 10-15’ wide at the entry point and built like a “swale” with gently sloping sides. Very easy to walk or drive through.
Now I know every site is different so yours may not respond like mine. I have watched our pond through the heaviest rains and watched it raise the pond level by a foot or better numbers of times. During the aftermath of Katrina we were hit with several days that dropped 6 to 8” of rain per day. That is the only time I have seen the spillway come into play and remember this pond was built by the state to collect area runoff. Even thought where the spillway narrows after the entrance it looked like a raging river the entry “swale” area may have had 6” of water moving through it that you could walk through if needed.
Given how new your pond is, great job by the way, I have to wonder if you are sure you will be dealing with as much spillway action as you are planning for. A bridge is nice but it is expensive, will require maintenance eventually and there are the liability issues others mentioned. Our nicely compacted clay swale has done the job here for over 40 years, is maintenance free and shows little signs of erosion. I am not saying I know your pond better than you just sharing our experience as food for thought.
